This is an HLK-PM03 along with an ESP8266 circuit over a small-sized protoboard. The final assembly will look something like this: It is also suggested that you add a slow blow fuse to it just before the HKL-PM03 converter as well as a capacitor to the output. You will see three wires: phase-out, phase-in, neutral wire. To begin with, you will need to get rid of the lid of the PIR motion sensor. It is divided into three different parts: Here the ESP8266 absorbs power via motion sensor phase-out wire with the help of HLK-PM03 AC/DC converter. The data is then sent to Node-RED with MQTT communication protocol. The project revolves around the modification of a commercial motion sensor through ESP8266 to register data whenever any movement is detected. You can find all assembly details for this device at ģ) Hacking PIR Motion sensor with an ESP8266 It can also help in monitoring soil features like temperature, humidity, moisture, and others for agricultural purposes. It can play a key role in building your own IoT based home automation system for turning on fans and lights in your apartment through your smartphone.
