STEVAL-BLUEPIRV1

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 analogue 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 BLE 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.
