    Involvement Level: Expert (understands the inner workings)

    Pros: Very fast response in time. Temp and humidity are accurate. It has the pull up resistor on board and mounting hole. It has also cables to connect it. Perfect sensor for temperature and humidity.

    Cons: There is nothing wrong with this sensor, It is accurate on measuring the temperature and humidity. Precision is very good, +/- 2% on RH and +/- for temperature.

    Other: There are a lot of informations on how to use it with Arduino, Raspberry Pi and other development platforms on the web. the DTH22 class for Arduino is straight forward to use.

    Involvement Level: Expert (understands the inner workings)

    Pros: More accurate than the little brother DHT11. If you are interested in 0.5 degrees, this is your sensor. Works well with the arduino's DHT library (there is a library for the DHT11, another for the DHT22 and a library for both --> saves bytes in your sketchs). Works with 3.3Volts and 5V. The sensor works well. Only 3 wires: GND, GCC and the signal.

    Cons: The sensor is bigger than the DHT11, you need more space. And the price is little high.

    Other: You can meter the temperature in 0.5 steps.

    posted by joliva on 10:15:27 G1T 10/01/2013 certificated customer

    Involvement Level: Expert (understands the inner workings)

    Pros: In just one component, it allows you to get measures regarding temperature and humidity. Accuracy is ok, just what description of the component said. Easy to use and comes with a cable that can be used directly with the Sensor Shield (for example) without the need of using any other extra component (resistors, etc).

    Cons: It is big. You can find temperature sensors much smaller than this component. A bit expensive knowing it is just a temperature/humidity sensor.

    Other: Arduino enthusiast

    Involvement Level: Expert (understands the inner workings)

    Pros: Works as expected from DHT22 / AM2302 device. 20cm cable to connect the sensor to Arduino sensor shield has been included. Note that 10k pull-up resistor is already soldered into DHT22 board, so you need no extra parts.

    Cons: None I could think of... Only price :-)

    Other: Good device for hobbyists, one sensor for the price of mini meteostation.
