STMicroelectronics STHS34PF80 Low-power Infrared Sensor
High-sensitivity infrared (IR) sensor for presence and motion detection
The STHS34PF80 is an uncooled, factory-calibrated, infrared motion and presence detection sensor with operating wavelength between 5 µm and 20 µm.
The STHS34PF80 sensor has been designed to measure the amount of IR radiation emitted from an object within its field of view. The information is digitally processed by the ASIC, which can be programmed to monitor motion, presence, or an overtemperature condition.
Thanks to its exceptional sensitivity, the STHS34PF80 can detect the presence of a human being at a distance up to 4 meters without the need of an optical lens.
The STHS34PF80 is housed in a small 3.2 x 4.2 x 1.455 (max) mm 10-lead LGA package.

STEVAL-MKI231KA: Evaluation Kit
Composed by STHS34PF80 industrial board and standard DIL24 adapter
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.
 STEVAL-MKI231KA Evaluation Kit Data Brief | 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. |
