I've been playing around with a couple of ESP32 microcontrollers, and that experimentation has taught me a lot about sensors and what you can build for really, really cheap. For as little as $4, you ...

For smart home deployments, there are a lot of ways to track the presence of individuals in a room. There are motion detection sensors that use mmWave and PIR, and you can also use simple detection ...
