Hi Allan
If you have any small breadboard you can easily test the sensor.
You can find here some info about how to do it:

Here is the DHT22 pinout:

I already have heard of some DHT22 with the GND swapped with the NC pin.
It's safe connect both together. On the RX board the two are connected to GND.
