STEVAL-BLUEPIRV1 Wireless motion detector based on Bluetooth Low Energy and PIR sensor

The STEVAL-BLUEPIRV1 evaluation board is an application example design of a wireless motion detector based on a passive infrared (PIR) sensor and featuring Bluetooth® Low Energy wireless connectivity.

The passive infrared sensors are the most used sensors for motion detection, thanks to their low-power consumption and price.

The STEVAL-BLUEPIRV1 evaluation board uses IRA-S210ST01 by Murata. The detection range of the IML-0688 Fresnel lens is up to 5 m.

The on-board low-power TSU102 CMOS op-amp and TS883 comparator perform the analog signal conditioning with a power consumption in a sub-μA range.

The embedded BlueNRG-M2SA FCC and IC certified radio module (FCC ID: S9N-BNRGM2S and IC: 8976CBNRGM2SA), which integrates an application microcontroller based on an Arm®Cortex®-M0 core, features the Bluetooth® Low Energy connectivity.

The whole design has been built by focusing on low-power consumption. Even though powered via a CR2032 coin-cell battery, the board expected lifetime is around a year.
