Welding the circuit according to the schematic. The front after welding： The back: Use the multimeter to measured if the welding is correct. Measuring principle: use wire connect two nodes, the resistance is almost zero. Measurement method: use the multimeter ohm, if the display value close to 0, that means welding success, otherwise there is a problem. Then need to measure the power and GND whether short circuit.
Reason: When the sensor detects the body, OUT pin will output high level, using the LED to display, so easy to debug.
ResultEnter the room, it automatically broadcast: "master: hello! Welcome back", and go out automatically broadcast: "master remember to lock the doors and Windows", similar to the electronic welcome device. The issue need pay attention
