The maximum cable length can be up to 30 meters

... About the AM2302/DHT22 Temperature and Humidity Sensor

The AM2302 and DHT22 sensors share the same characteristics. From my perspective these sensors are the same. The DHT11 on the other hand is a little cheaper but only intended for indoor use. On e-Bay you can find a pack of 5 peaces of the AM2302 for about 17 EUR with free shipping.
The sensor is already calibrated by the manufacturer. It is almost plug and play.
Unlike some temperature sensors, each of these temperature and humidity sensors requires its own data line. So connecting several sensors on a single one-wire bus is not supported because the sensor does not have an address.

The maximum cable length can be up to 30 meters / 98 feet if you use 5 V power and 1 meter / 3.3 feet if you use 3.3 V power (see Datasheet). In this how-to I will use 3.3 V because the voltage of all RPi's GPIO pins, which can be used as data pins, is 3.3 V.
The sensor contains an 8 bit micro-controller. The sensor has an average power consumption of only 0.3 mA (300 micro ampere). The low power consumption is achieved by going into sleep mode periodically. A new sensor value can only be obtained every 2 seconds...
