Code

Arduino

Grove library

• Library: Sketch > Include Library > Manage Libraries... > Grove DHT11 > Install
• Example: File > Examples > Grove Temperature and Humidity Sensor > DHTtester
  • In the example code, make sure to uncomment DHT11

    #define DHTTYPE DHT11 // DHT 11
    //#define DHTTYPE DHT22 // DHT 22 (AM2302)
    //#define DHTTYPE DHT21 // DHT 21 (AM2301)

  • If you get #error "CPU SPEED NOT SUPPORTED" for the nRF52840, use this code

    #define DHTCOUNT 20 // experimental value for nRF52840
    #define DHTPIN 2 // sensor connected to pin D2
    DHT dht(DHTPIN, DHTTYPE, DHTCOUNT);
