It is really easy to use. Only has 3 wires: Signal, 5V and Ground (GND) and you can measure temperature and humidity. Price is very good and the sensor works fine. You can find lot of examples on internet. Just attach to Arduino, download the library and start measure.
You can't measure temperature under 0 Celsius and the accuracy it not very well. Other sensors as a LM35 is better. For measure humidity is a good sensor, however it is a bit slow when the humidity changes quickly.
It is an useful module for arduino when you want to measure temperature and humidity.
