Sensors Projects

A Picaxe 08M2 microcontroller and an HIH6030 sensor team up to easily control a ventilation fan using temperature or humidity or both.

In this article, we’ll develop and test an algorithm for automatically shutting down a robot in response to a collision (or some other violent event)....

In part two of the tachometer/speedometer project, we'll add a keypad and LCD for easier user interaction.

An accelerometer can be a valuable addition to a robotics project. This article will show you one approach to generating and analyzing acceleration data....

This project uses a C8051 microcontroller development kit, an accelerometer evaluation board, and Simplicity Studio IDE—all from Silicon Labs—to rather quickly and easily build a...

With all this hot weather this summer, we need to keep our plants well-fed. That's where the Debra 2 Moisture Sensor comes in!

Use an Arduino/Genuino 101, a TI SensorTag, and an SD shield to build a BLE multi-sensor data logger that records temperature, humidity, atmospheric pressure, ambient light and more....

The BNO055 is an absolute orientation sensor from Bosch that combines sensor data and a microprocessor to filter and combine the data, giving users their absolute orientation in space....

In this article, I'll show you how I used one of my SIM900A GSM modules to send temperature and relative humidity to my personal website....

Remote controls for electronics often use IR (infrared) radiation in a very precisely coded sequence for channel surfing, volume adjustments, and more. One of the most popular codes is the SIRC...

The Beaglebone Treat-Feeder is the prototype for a great pet-feeding device! Keep track of your pet's diet while you stuff your face!

Tracking an infrared light source is not as difficult as you might think; a 14-pin PICAXE, a stepper motor with a driver IC, three phototransistors, and a few other components will do the...

Use I2C on the Quark D2000 development board to interface a color sensor and get acquainted with using asynchronous mode.

Get acquainted with using I2C with the Quark D2000 development board by interfacing an ambient light sensor and an LCD.

Need to ventilate a room? This article will show you how I made a relay-operated, GPS-timed fan to vent out the moist air in my boat's cabin. It is controlled with a PIC16F628A and has an LCD....

This project gives you an example of how a basic user interface can be implemented using only one circular capacitive touch sensor.

A PICAXE 08M2 can be used to read the amount of IR (infrared) light falling on a phototransistor and respond by moving a servo to a predetermined position....

The motion-activated Santa Cam is sure to catch who is stealing your milk and cookies this holiday season! You can even use it for a photo booth this New Year's Eve!...

In this project we will develop an algorithm for precisely locating a touch event that occurs somewhere on a circular capacitive sensor.
