Great for Calibration

Used it to calibrate cheaper sensors for a home air quality hobby project. Very useful.

Good Product - Quick to arrive and quick to set up

Very satisfied with the purchase. The sensor came in a couple of days, and it was easy to write a little code on a raspberry pi to read and save the data. The device seems to be very accurate and responsive. I also really appreciate the extensive hardware documentation. It also feels good to support an American hardware company, since the market seems to be dominated by Chinese or Indian sellers.


Great but thought it read temp/rh as well, could make that a little more clear by offering the version that does as well

"Easy to install, easy to set up, and easy calibration - just what I was looking for."
