    I am a member of a college team that has entered the high-powered ESRA (Experimental Sounding Rocket Association) launch competition for the last two years, and we are currently working on our third year entry. Prior years have revealed a common complication with heating that affects our rocket’s main controller board and payload. Enough so that we had to cancel our launch at the competition last year, and nearly half of the high-powered rockets that were launched had some sort of complication linked with overheating (including, but not limited to, complete controller failure resulting in the destruction of the multi-thousand dollar rockets, which also endangers the lives of students at the launch site if a chute fails to deploy.)
    This year our team plans to run extensive tests to discover how heat travels through our rocket design, and how we can influence it. The Thermo 6 Click Board is compact and light enough that it can be mounted onto our controller without requiring significant recalculations, and can provide us with valuable data that will be used to determine if our rocket is safe to launch or not.

    I would like to use the MAX31856EVSYS Evaluation System to build a temperature monitoring device for my smoker.  I have a basic smoker and the temperature fluctuations can happen very easily.  The device I would create would mount a thermocouple inside the smoker so I can accurately monitor the temperature and send me a notification if the temperature goes out of range from my set points.


  • staufr 2017-10-28

    Using the MAX31856EVSYS Evaluation System I would like to build a home temperature monitoring system. We have always wondered if our thermostat is in the best position in our house. If I could place multiple temperature monitoring units in different rooms in our home and monitor the room temperatures I could find a better location for our thermostat.

    I am a hobbyist who just wanted to be a part of this phenomenal contest! With high hopes and dedication I enter this contest and here is my idea!

    The idea is to create a compact device codenamed Season using MikroElektronika’s Thermo 6 Click Board which is featuring a MAX31875 that will give you the temperature of it’s surroundings as well as one area of your interest. My main focus is to make this into something that people of any age would fall in love with. This is why I also want to give it a bit of personality too and have it become your perfect morning coffee pal!

    My vision for this is not to build a thermometer, but something far better yet fairly simple. Season’s goal is to grow to be your morning pal and bring a smile to your face.

    Love Mondays and have this little buddy prepare you for where you are heading!

    I like to provide food for my family. An easy way to do it is hunting or fishing, and it’s enjoyable… except when it’s cold. My idea is similar to heated jackets. It’s heated boots. I ice fish and deer hunt every year and every year I’m buying more wool socks thinking maybe these will do the trick. But every year I’m disappointed and have to leave the woods or ice early. The thermometer will sense ambient temperature around the feet and when it gets below an ideal comfort level, insulated conductive metal yarn will activate, warming the boots. It’s not on 100% of the time , just when it senses the temp around the feet to go below a certain degree. As for power like the heated jackets, Milwaukee uses a rechargeable red lithium battery for the jackets. You’d obviously need one for both feet and I was thinking of a small pouch that buckles around your ankle that connects to it. That’s my idea.

      I forgot to mention that the Thermo 6 clock board is the one I had in mind for this project.

  • Stephen S. Madeira 2017-11-07

    I’m studying efficiency losses in 3-Phases power inverters for EV motors. Since temperature plays a big role with efficiency, this small device - MAX31875 - would allow me to track each IGBT’s and Diodes’s temperature, making possible to always reach the optimal performance of the system and then, wasting less energy or even use it as a safety device, turning off the motor in extreme conditions (overcurrent, short circuit failures and etc). The Click Board would make everthing easier to use this sensor.

    I would like to use the MAX31856EVSYS module of the Maxim, to monitor the temperature of perishable products on supermarket shelves. When it detects a variation in temperature (which would make the product damaged), would be created an alert for immediate correction of the problem; avoiding the loss of product

    I would like to build a heated smoothing chamber for 3d prints.  Smoothing 3d prints is a new hobby of mine in which I’ve been using a ‘cold vapor’ method which takes hours. I’ve perfected this method with great results but am not satisfied with the amount of time it takes. Heating the solvent will reduce the time required to just a few minutes. 
    I would like to use the MAX31856EVSYS with thermocouple and a microcontroller to monitor and control the heating and distribution of different solvent vapors. It would consist of a smoothing chamber and heatable solvent chamber connected via solvent resistant tubing. I would like it to be a closed system so it could be used indoors without stinky or harmful vapors.  The idea is that you can place your 3d model inside the smoothing chamber, select the settings appropriate to the smoothing solvent and press a button to heat the solvent to appropriate temperature. The vapor created in the solvent chamber would be pushed through the tubing and into the smoothing chamber for a specified duration.  Voila! Super-fast, Super-smooth 3d prints at home.

    In the January, 2011 issue of QST, the ARRL’s amateur radio magazine, I described how to use a domestic toaster oven to reflow solder printed-circuit boards.  It required the user to turn the heating element on and off manually while monitoring the temperature.  I plan to use the MAX31856EVSYS temperature sensing system, along with a Raspberry Pi as the main controller, to automate and control the entire process.  The user will just need to put his pc-board in the oven and press a button and the controller will do the rest.

    We’re currently dealing with an elder-care situation in our home since my father-in-law has moved in with us. His diminished capabilities has created a number of complications around here and one involves temperature. He lives in a semi-detached apartment which has it’s own kitchenette. The issue is that while we want to have very hot tap water available for cleaning and sanitation, there is the potential for him to seriously burn himself if he becomes confused between the hot and cold water faucets (which has happened in the recent past). My thought is to use the MAX31856EVSYS to monitor the temperature of the water as it enters the drain pipe of the kitchen sink, and use a solenoid to physically shut down the hot water if a maximum temperature is reached. A hidden (or secured) defeat circuit would allow me or my wife to run very hot water for cleaning when necessary. This system would allow him the sense of independence while protecting him from a potentially hazardous situation.

    I want to use the MAX31865 IC for my Smart Home automation project, which I believe is not possible without the temperature sensors. Particularly, I would use the IC for my battery powered wireless outdoors temperature sensor, as it perfectly fits for it with the low power consumption and could give the long time of service without the need for recharging. I think, the MAX31865 Evaluation Kit is the best choice for evaluating in my project.

  • momososo 2017-11-12

    I want use MAX31856EVSYS to build a boiling water confirm system.
    Most people closed fire when seeing water boiling. Is the water temperature high enough to kill microbes?
    First, I will install thermocouple into glass tube and use it to measure water temperature. That can keep water clean and make sure measurement is precise. Second, connect thermocouple with MAX31856EVSYS and an arduino board connected then a LCD to display.
    Why use MAX31856? Since I only have K type thermocouple and this system need contract measure.

    Title: Application of RTD sensor to measure the temperature of a Solar PV Panel and improve its efficiency
    One of the biggest challenges faced by the Solar PV industry is the losses due to increase in temperature of the PV panels in hot dry regions. It is imperative to measure the temperature of the panels to avoid failure. Current temperature sensors require complex systems and usually is limited by its range and reference values. The Maxim’s MAX31865 Evaluation Kit has the potential to vary the value of the RTD and reference resistor. This allows us to customize according to the need for the PV panel and size. The USB-SPI interface allows us to control and interact with the MPPT controller of the Solar PV charger. The feedback loop allows us to improve the performance of charger. Hence, this opens a wide range of possibility to control and monitor the panels in real time. It can also be used as an educational guide to study in small-scale projects.

    My new project is a colorimeter with dry heater block for cuvette temperature control. Precise temperature of the sample kept in the cuvette is to be maintained for precise determination of concentration of the material in the sample. Accurate temperature control of cuvette with samples is achieved by using a dry heater Aluminum block. Cuvettes are inserted to slots in the aluminum block and this block is electrically heated and temperature is set by the desired value by closed loop temperature control. Precise measurement of temperature demands a temperature transducer and signal processing. Since the temperature control is to be achieved by a microcontroller, digital output from the temperature transducer is needed.
    I am designing the temperature controller using the Integrated circuit MAX31856 that is ideally suited for this application. This chip uses a thermo couple sensor and provides all the needed functionality like automatic Linearization correction for different types of thermocouples, minimum error %, higher resolution, and input protection against ±45V, minimum component count, built in fault detection and management, noise rejection, simple SPI communication with the Microcontroller and so on.

    Unattended Stoves and fire place are one of the main causes of fire accidents, which unfortunately happened to me too, so I would like to monitor state of the stove, and if it is burning at high temperature for long time or just burning for very long time, then it will warn the persons in the house.

    warning system can be as simple as buzzer and lights to notification to mobile phones via sms or apps

    Hydroponic table top gardens would offer year round access to fresh greens such as lettuces, chives, herbs, and other suitable crops.  One of the important parameters that needs to be monitored is temperature.  Both the plant’s environment and the growing water are best maintained in a “warm” range.  The MAX31856EVSYS Evaluation System or MAX31865 Evaluation Kit would be suitable along with a waterproof thermocouple or thermistor.

  • AMolnar 2017-11-12

    I would like to use the MAX31865 Evaluation Kit to build a measurement system for the investigation of thermostimulated parameters (thermostimulated depolarization, current, thermoluminescence e.t.c) of ferroelectric materials. As far as I’ve read, this system has a 15 bit resolution, which is absolutely enough for our application. In addition, this kit uses a four-wire connection, which will allow the use of relatively long connecting wires.This is exactly what we need! These measurements are simple in technical implementation. However, the data obtained require complicated mathematical processing. Using the control computer allows you to obtain ready-made experimental data. Such a module would allow us to launch a new methodology.

    I would use MikroElektronika Thermo 6 click board as part of a wireless sensor system I would like to implement into my van. I own a 1984 VW kombi and would like to combine my passion for old vehicles and modern technology to create a wireless sensor system to monitor different components of the van. The overall project would include monitoring the fridge and freezer temperature, inside and outside temperatures, tire pressures, water tank levels and more. The system will communicate to a central control unit located near the driver via a zigbee or bluetooth low energy (BLE) network, with the readings displayed on an interactive screen. The thermo 6 board would be perfect for the temperature readings due to its low power draw, large operating temperature range and small size allowing it to be easily integrated into the BLE or zigbee network and hidden out of site. A common problem whilst traveling is the leisure battery running flat whilst the fridge is being powered from it. Embedding a temperature sensor into the fridge will allow for an alert to be raised if the fridge temperature rises to above a safe level for food to be kept.

  • I would like to use the Thermo 6 Click board for our automatic egg hatching machine product. Our hatching machine often used a DHT22 that was not quite accurate. So the result of hatching the eggs was quite low. I will test this device accuracy and I will use RaspberryPi for my controller with a 5” LCD Touchscreen and also a few motors for flipping the eggs twice a day and a spraygun motor for water mist so it will automate and control the entire process.  The user will just need to put the eggs into the machine and to determine what kind of eggs that they wanted to hatch. The machine will determine the hatching process and timing process based on the information that chosen.

    And also i will use an infrared sensor to sense each egg for life signs. When there is egg/s that did not have a life signs after 4 days, the user will be alerted to takeaway the egg/s through the touchscreen LCD and through the WiFi to Android App.

  • Few days ago I had an accident with my mobile phone,to be more precise the phone felt on the ground and the display has been broken.I found that on ebay,ali-express are some cheap displays for my phone.The problem after I buy a display was how to replace the old one,with a new.On youtube there were interesting tutotrials for how to replace it with an iron for clothes.And from there I came out with a concept for my project.
    The main idea is to build a PID controller with MAX31856EVSYS Evaluation System and to comunicate with arduino board to make the controller which it will be precisely and accurately measured the thermocouple probe nestled in the iron heater.Figured out that heater is going to be controlled by solid state relay. From the controller itself there will be relay for vacuum pump,so the display can’t be moved while it is heating, TFT display and rotary encoder will be added for the interface of this display replacement iron.
    That’s the idea,I hope it will help to other makers and hobbyist for replacing a display to a damaged phones.
