    I think this device would be a good addition to a 3d magnetic sensor I have.  My plan is to create a speedometer with the magnetic sensor for my bike and transmit the data using Bluetooth to my phone.  It’s ideal because no wires would be required from the sensor to the phone, making installation simple.

    We need to measure the angle of the z-axis of a medical device and transport this info wireless. BTLE seems to be the ideal medium. On the other side, its important, that we can run the device around 6 month without battery change, so energy consumption is relevant for our wireless angle sensor.

  • Somtochukwu Paul 2018-10-02

  • drakkzharr 2018-10-06

    I’m designing a system that exchanges real time sensor data between multiple wearables(activity trackers) and a central device. The plan is to use it during fitness group sessions to display heartrates and kcal on a large beamer or screen. The problem is that there aren’t many activity trackers that share real-time sensor data with custom devices. For most of the big brand activity trackers you’ll need to use their SDK and API’s but these don’t allow real-time raw data exchange.

    This bluetooth module would be great to build a custom activity tracker.

    I want to make an instrument with it. It is basically a susceptometer, a device used to measure the susceptibility of a magnetic substance. Since its operating temperature is -40 to 85 deg-C we can measure the variation of susceptance as a function of temperature for various ferromagnetic materials. The data can be sent via Bluetooth to a PC where all the measurements are logged.

  • pilewis 2018-10-11

    This module is ideal for the application of remote monitoring of health devices.  It is ideal for those who may not have easy access to hospitals and also would allow for remote monitoring of patients.  Like myself who suffers from OSA (Obstructive Sleep Apnea) this module could be used and incorporated into a CPAP machine.  In addition it can be linked to multiple function capture devices to enable sending of information via mobile communications or the internet.

  • ademu 2018-10-12

    In appartment block central heating systems the water temperatures need to be guarded against legionella (veterans disease). A wired connection to the heater controller is not allowed, but adding e.g. DS1820 sensors to the hot water pipes is. Access to the logged data can only be done wireless since access to the heater room is for technicians only. I will use the kit to log data and read out the logged data using BLE from outside the room, a 10m range is enough. I already have permission to hook up a battery powered set to sensors on the pipes.

    The device sounds like it will be a very power-efficient controller as well as transceiver for weather station instrumentation sites.  It seems like a strong competitor to the ESP32 device which I have been considering for replacing my current outstation transmitter.  The ability to add mesh capability will allow a multi-station setup to add remote monitoring of livestock as well as orchard.  Thanks for considering this application idea.

  • Jeff Verive 2018-10-28

    A nice application would be to incorporate Bluetooth into smart glasses or similar wearable device to alert a user of dangerous conditions. One particular project I am engaged in is a pain flare predictor for chronic pain sufferers, which senses (or receives over Wi-Fi) environmental conditions such as humidity, temperature, and barometric pressure to alert the user when conditions are right for a pain flare. This allows the user to take pro-active steps to reduce or even eliminate pain flares, and may even be applicable to other conditions - for example, measuring a diabetic’s blood glucose levels and rate of change to improve control. I already have the pain flare predictor working on a smart watch platform, but it would also be useful with smart glasses, smart TVs, and smart lighting.

  • Dixon Selvan 2018-10-28

    Fall Monitor: The placement of the system can be as a pendant which can be worn around the neck or as a card which can be kept in the pocket. The system then will monitor the position and acceleration of the person who is having it. When that person encounters a fatal fall and is unable to recover and stand to feet for a per configured duration, then the system sends an alert to the mobile app which then triggers SMS to a preconfigured number for help.
