Bluetooth Coin Sensors

We are the Circuits Group of the National Technical University of Athens. We specialize in designing systems for sensor, data acquisition , IOT, biomedical and RF applications. In this project we developed very compact, coin sized sensors for IOT applications. These sensors have 1.1inch diameter and are battery powered (1 CR2032 Battery). The battery life is approximately one year for the Temperature- Humidity sensor and a couple of months ,depending on use, for the Accelerometer - Gyroscope sensor. They are both connecting to an android application using Bluetooth 4.0. The application can save the collected data to the phone's memory or upload them to an online database.
