SmartHome-Wireless Touch Switch

This circuit is a touch switch, which can replace the wall switch, and allows you to control the lighting (turn on and off, I want to make another board to adjust the brightness in the future), using two PCBs, the first one is black, including the microcontroller , Antenna, etc., the second PCB is red, including AC parts, power supplies, relays, etc.

characteristic:

-ATmega328P 3.3V 8Mhz microcontroller with pads for external oscillator (optional)

-Antenna NRF24L01 SMD-

The touch button TTP223 + HTTM photo reflector can interact with the switch manually.

-RGB LED (blue without PWM) indicates the status of the relay or RF connection.

-Flash memory chip for FOTA

-Chip ATSHA204A for signature.

-JST-8-1MM AVRISP + UART programming connector (UART requires 100nF capacitor in the cable)

-2 5A HF46F-5-HS1 relays to control AC load

-DS18B20 sensor near the power supply to control the internal temperature.

-Power HILINK HLK-PM01 5V-

Voltage regulator AMS1117-3.3

Claim:

-The neutral wire must be connected to the power supply.

-You must use a 3D printer to print two pieces of plastic to accommodate the circuit, hold the glass and fix the screws to the wall.
