Block Diagram

The complete device makes use of Insight SiP ISP1807-LR Long Range BT5 module together with low power 3-axis Accelerometer, Temperature / Humidity and Barometer sensors connected to a primary button cell battery CR2032.

The ST Micro LSM9DS1 3-axis linear accelerometer and 3-axis magnetometer is used to detect acceleration and is combined with the ST Micro LPS22HB Barometer and the SHTC3 Sensirion Humidity / Temperature sensors. A Rohm SML-P11MTT86 mini-LED is also part of the board and is available to be controlled by software. Data are transmitted via GPIO processor port.
