How to simulate the DHT22 / AM2302 in LabWired

  1. Open the Playground at app.labwired.com and place an MCU board.
  2. Add the DHT22 / AM2302 (catalog type dht22).
  3. Connect VCC and GND to the supply and ground of the board.
  4. Connect DATA to a free GPIO pin.
  5. Run the firmware. It drives and reads the pins of the part, and the device model responds on those pins.
