I'm looking forward to getting an accurate humidity and temperature sensor.
Right when I decided to go with a DHT22 module, I saw AM230x (AM2301, for example).
- How do I choose between DHT22 and AM2301?

The AM2301 and the DHT22(AM2303) are similar in a number of ways, both in price, specs, ranges and power consumption. They are usually cased a bit of a differently, with the DHT22/AM2303 being packaged with four pins (only three are in use), and the AM2301 (formerly called DHT21) is packaged with three cables and a small plug inside of the case.
I would choose based on the usage, if I'm going to use the sensor on a breadboard or a socket (going for the DHT22 pinned version), or if I'm going to have it standalone (the cabled one).
