 for DHT22 I used the library from https://github.com/beegee-tokyo/DHTesp, as the standard library gives to many wrong readings<br>
 Now the DS18B20 is supported as well - uncomment line 31: // #define DS18B20    // use this if you use DS18B20, default ist DHT22<br>

 - DS18B20 support (setable in config.h)
 - GPS switched off in WX_FIXED mode (only available with boards with HW-Version >=V1.0)
 - immediate TX with short key press
