I don't remember where I bought this kit. It's branded "Robotlinking" but robotlinking.com is gone, now it's https://sunfounder.com/

Today I am looking at making a closet light. I had an IKEA light in there but it quit. It uses a reflective sensor and an LED strip.

I think I can put one of the reflective sensors from the 37 sensor kit. They have "Avoidance" and "Tracking" sensors. I can just hook them up to a spare M5StickC and there you go. It will send MQTT updates to Home Assistant and HA will tell the light to go on via a Martin Jerry switch. "Simple". Ha.

Avoidance module

Tracking module

3 pin connector: signal, power, ground Mine has 4 pins, this one has only 3. (One pin is NC)

It has an LM393 comparator. Sensitivity can be adjusted with a trimpot. It has 2 visible LEDs to give status. D1 show power (labeled "PLED"). D2 shows state ("SLED").

Tracking module

This is probably the same design for the Avoidance sensor though the board layout has changed.
