It works It's cheap Temperature and humidity readings are reasonably stable and precise.
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.
To calibrate these, I'm afraid you're going to have to use . . . math.
Temperature sensor for indoor use, that requires you do a little bit of thinking, measuring and testing if you want accurate readings.
