Product review (4 stars): Great, cheap, easy to use little device for Arduino
Seems to work well most of the time, was easy to wire up to a little breadboard and Arduino MKR1000. I'm not sure if it's because my connections aren't solid, this device is cheap/inaccurate, or some other reason, but it seems like every so often the temp & humidity will randomly return a 10-15% lower value and then go back to what seems to be an accurate reading. I have it checking temp & humidity every 2 seconds and reporting to an online IoT service every 20 seconds or so.
