Description

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.
