Note:
This Grove - Temperature and Humidity Sensor Pro and our another product
Grove-Temperature and Humidity Sensor are sharing this library. No matter which product you
are using, make sure that you have made the definition line of the sensor of your board into
effect and commented out the definition lines of other specs. For example, the sensor we used
on Grove - Temperature and Humidity Sensor Pro is DHT 22. So the definition part of the
sensor spec should be:
//#define DHTTYPE DHT11 // DHT 11 #define DHTTYPE DHT22 // DHT 22 (AM2302) //#define DHTTYPE DHT21
// DHT 21 (AM2301)or
4. Upload it into your Arduino board.
