Tuya Zigbee presence and lighting sensor ZY-M100-L and ZY-M100-S are used to turn on lighting devices.
But they can also be used in other scenarios.
The devices are built on a microwave FMCW radar that allows you to measure range and speed.
Microwaves pass through plastic, wood, plasterboard, gas blocks and concrete. They do not pass through metal, but they pass through a mirror.
