Reasonable sensor – DHT11 Arduino Compatible Digital Temperature Humidity Sensor Module Reviews

Involvement:Expert (understands the inner workings) - Ownership:more than 1 month

Pros:
It works It's cheap Temperature and humidity readings are reasonably stable and precise.
Cons:
Sensor is inaccurate, you need to calibrate it in your code. Slow to respond to changes in environment. Small range of sensitivity 0-50c (32-122F). Not well protected. Those last two means, probably indoor use only.
Other:
To calibrate these, I'm afraid you're going to have to use . . . math.
Bottomline:
Temperature sensor for indoor use, that requires you do a little bit of thinking, measuring and testing if you want accurate readings.
