STMicroelectronics PIR Sensor Expansion Board for Murata IRA-E700ST0 STM32 Nucleo

The STEVAL-IDI009V1 evaluation board conditions the signal generated by an on-board passive infrared (PIR) sensor for applications such as security alarms. A person moving in range of the sensor triggers a detection event, which can in turn be used to trip an alarm or command room lighting to be turned on, for example.
