Hi Gunter,
please take a look into the Firmware Configuration section of the Readme .

I assume you are familiar with the Arduino IDE. When you open the weatherradio.ino firmware, there are several header files included. All configurations should be placed in config.h:

  1. Enable DHT sensor by removing the comments from
    //#define USE_DHT_SENSOR
  2. Set the appropriate digital PIN of your Arduino where the DHT sensor is attached to and select the DHT type:
    // DHT sensor family
    #define DHTPIN 3          // Digital pin connected to the DHT sensor
    //#define DHTTYPE DHT11   // DHT 11               - Uncomment whatever type you're using!
    #define DHTTYPE DHT22     // DHT 22  (AM2302), AM2321 - Uncomment whatever type you're using!
