Presence detectors/Sensors are essential for today’s home automation systems In earlier videos we looked at PIR and radar sensors, and we were even able to use Wi-Fi on our smartphones to sense our presence. All have advantages and disadvantages.
Today, we create the ultimate presence detector. And the best: It costs only a few dollars. How does this ultimate presence sensor work? Of course, with Bluetooth low energy and an ESP32.

- In this tutorial we will build a valuable BLE application which can solve a real problem
- We will learn how BLE advertising in detail works
- We will trace BLE packets to the last bit. I am sure this will help us in future projects
- We will connect the sensor to Mosquitto MQTT broker and to Node-Red on a Raspberry Pi
