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.

The STEVAL-C34KAT1 is a multisensing expansion kit that includes the STEVAL-C34AT01 expansion board and a flexible cable.

The STTS22H temperature sensor is placed on the PCB side and is thermally coupled to the PCB bottom exposed pad through vias. The expansion board can be mounted on the equipment for the vibration analysis using the four holes or the double-sided adhesive tape. This board is compatible with the STWIN.box kit (STEVAL-STWINBX1).

The STEVAL-C34KAT2 is a multisensing expansion kit that includes the STEVAL-C34AT02 expansion board and a flex cable. The ISM330IS sensor is soldered at the center of the small 25 x 25 mm board. The STTS22H temperature sensor is placed on the PCB side and is thermally coupled to the PCB bottom exposed pad through vias. The ISM330IS is a system-in-package featuring a 3-axis digital accelerometer and a 3-axis digital gyroscope, boosting performance at 0.59 mA in high-performance mode and enabling always-on low-power features for optimal motion results in industrial and IoT solutions. The ISM330IS embeds a new ST category of processing intelligent sensor processing unit (ISPU) to support real-time applications that rely on sensor data. The ISPU is an ultra-low-power, high-performance programmable core, which can execute signal processing and AI algorithms in the edge. The main benefits of the ISPU are C programming and an enhanced ecosystem with libraries and third-party tools/IDE. Its optimized ultra-low-power hardware circuitry for real-time execution of the algorithms is a state-of-the-art feature for any wireless sensor node from small equipment or accessories to enterprise solutions for industry 5.0 (anomaly detection, asset tracking, factory automation). The expansion board can be mounted on the equipment for the vibration analysis using the four holes or the double-sided adhesive tape. This board is compatible with the STWIN.box kit (STEVAL-STWINBX1).
