I built an ESP32-powered presence sensor using only Bluetooth, here’s how it works
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 mechanisms like a door opening or closing with a door sensor. However, to detect continued presence, things get a bit more complicated. Many sensors claim to be able to detect continued presence, but I've found that sitting still (common when lying in bed or watching a movie on the couch) can trick them easily. That's why I built a presence sensor with an ESP32, and it works perfectly.
