STMicroelectronics STEVAL-BLUEPIRV1 evaluation board is an application example design for a wireless motion detector based on a passive infrared (PIR) sensor and Bluetooth Low Energy wireless connection. The low-power design gives a single CR2032 button battery an expected battery life of about a year

STMicroelectronics' STEVAL-BLUEPIRV1 evaluation board is an application example design of wireless motion detector, based on passive infrared (PIR) sensor and Bluetooth Low Energy wireless connection. The low power consumption design enables the expected life of a single CR2032 button battery to reach about one year.

The onboard low-power TSU102 CMOS operational amplifier and TS883 comparator perform analog signal conditioning, and the power consumption is- μ A range. With Arm based Cortex - The embedded BlueNRG-M2SA (FCC ID: S9N-BNRGM2S and IC: 8976CBNRGM2SA) of the application microcontroller of the M0 core can realize low-power Bluetooth connection.
