The STEVAL-MKI231KA demonstration board is a kit made up of an ad hoc PCB, mounting the STHS34PF80 low-power, high-sensitivity infrared sensor for presence and motion detection, which is connected through flat cable to a generic adapter board (STEVAL-MKIGIBV5) to make it compatible with the STEVAL-MKI109V3. An ad hoc plastic holder with a Fresnel lens (TMOS63-10) has been provided into the kit to verify best performances of the device.
The STEVAL-MKIGIBV5 can be plugged into a standard DIL 24 socket. The kit provides the complete STHS34PF80 pinout and comes ready-to-use with the required decoupling capacitors on the VDD power supply line.
This adapter is supported by the STEVAL-MKI109V3 motherboard, which includes a high performance 32-bit microcontroller functioning as a bridge between the sensor and a PC, on which it is possible to use the downloadable graphical user interface (Unico-GUI), or dedicated software routines for customized applications.
It is also possible to plug the board into X‑NUCLEO‑IKS01A3, X‑NUCLEO‑IKS02A1 or X‑NUCLEO‑IKS4A1. The kit is included into an X‑CUBE‑MEMS1 expansion software package for STM32.
