the size of the AC line dropper capacitor. A high-voltage capacitor and a high-speed switching diode 1N4148 are needed to filter out the AC current and supply a DC current for the MCU. Between the V DD and the 1N4148, a 3.9 V Zener diode is used for the MCU voltage regulation. Testing shows that such
