Power voltage should be between 3.3V and 6V DC. When power is supplied to sensor don’t send any instruction to it within one second to pass unstable status. One 100nF capacitor can be added between VDD and GND for wave filtering.

Small size & low consumption & long transmission distance (20 meters) enable AM2303 to be suited in all kinds of harsh applications.

The AM2302 has a built-in pull-up resistor, whereas the DHT22 does not. Apart of that and de different housing they should be technically identical.
