Assuming you mean connecting the ESP32−DEVKIT−V1ESP32-DEVKIT-V1 (ESP32 DevKit V1) (U1)(U1) to an ArduinoNanoArduino Nano (Arduino Nano) (Q1)(Q1) for UART communication, you can follow these steps for wiring:
  1. Power Connections:
    • Connect (U1:3V3)(U1:3V3) to a 3.3V power source if needed for any additional sensors or components.
    • Connect (Q1:5V)(Q1:5V) to a 5V power source, this is usually provided via USB for the Arduino Nano.
    • Connect (U1:VIN)(U1:VIN) to (Q1:5V)(Q1:5V) if using the ESP32 powered by the Nano.
    • Connect (U1:GND)(U1:GND) to (Q1:GND)(Q1:GND) to ensure they share a common ground.
  2. UART Communication:
    • Connect (U1:TX0)(U1:TX0) (pin 13 TX0) to (Q1:D0/RX)(Q1:D0 / RX).
    • Connect (U1:RX0)(U1:RX0) (pin 12 RX0) to (Q1:D1/TX)(Q1:D1 / TX).
The specific connection list based on your provided designators and pins is:
  • Connect (U1:GND)(U1:GND) to (Q1:GND)(Q1:GND).
  • Connect (U1:VIN)(U1:VIN) to (Q1:5V)(Q1:5V).
  • Connect (U1:TX0)(U1:TX0) to (Q1:D1/RX)(Q1:D1 / RX).
  • Connect (U1:RX0)(U1:RX0) to (Q1:D0/TX)(Q1:D0 / TX).
These connections allow the ESP32 to communicate with the Arduino Nano via Serial (UART)(UART). If you need to power the ESP32 from the Arduino, ensure the voltage levels are compatible or use a suitable power regulator or level shifter.

To connect the PMS5003 sensor (U5) to the ESP32 (U1), you need to wire the pins as follows:
  1. Power Connections:
    • Connect U5:VCC to U1:3V3 (3.3V supply)
    • Connect U5:GND to U1:GND (Ground)
  2. Communication Connections:
    • Connect U5:TX to U1:RX2 (ESP32 UART receive)
    • Connect U5:RX to U1:TX2 (ESP32 UART transmit)
  3. Additional Control Connections:
    • Connect U5:RST to a GPIO pin on U1 (optional for reset control)
    • Connect U5:SET to U1:GND (to enable sensor; typically set low to operate)
Here are the specific connections in the required format:
  • Connect U5:VCC to U1:3V3.
  • Connect U5:GND to U1:GND.
  • Connect U5:TX to U1:RX2.
  • Connect U5:RX to U1:TX2.
Optionally:
  • Connect U5:RST to a free GPIO pin on U1.
  • Connect U5:SET to U1:GND.
