Introduction
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: 8976C-
BNRGM2SA), 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.
