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.
