The STEVAL-PDETECT1 is a presence detection add-on evaluation kit for STWIN.box, targeting human presence applications. It enables low-power applications, user privacy, and it reduces false triggers with multisensor modalities.

It is possible to use simultaneously up to three add-on boards in a daisy-chain configuration.

The kit is based on three sensors: STHS34PF80, VL53L8CX, and VD6283TX.

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.

The VL53L8CX is a multizone (either 4x4 or 8x8) ToF ranging sensor, which enhances performance under ambient light with a reduced power consumption. Based on STMicroelectronics’ FlightSense technology, the sensor is designed to provide accurate ranging up to 400 cm with a 65° diagonal field of view (FoV).

The VD6283TX (1.83 x 1.0 x 0.55 mm) is ST's new color sensor with advanced light flicker extraction. Light measurement is fast and accurate thanks to an individual ADC and a readout for each color channel. The VD6283TX uses hybrid color filters with precise responses allowing accurate computation of the correlated color temperature (CCT) and Lux information. The VD6283TX can be used for display brightness management or scene light correction.
