The XIAO Smart IR Mate is a compact circular-shaped IR remote hub/blaster built around the XIAO ESP32-C3 and designed for IoT ...

A row of infrared lights act as sensors and can detect the point on which a finger occludes the light. This will register a single point of interaction, pretty much like a tap on a touchscreen.

Each small circuit board contains four infrared sensors that detect anything closer than 1 centimeter. “We thus simulate light touch,” explains Mittendorfer.
