    best sensor there is

    the title is NOT exaggerating. once you spent hours of debugging and research you figure out SHT30 is the best. one example would be: check your sensors after 12 months and see how accurate they are. SHT20 or others used in the industry fall behind after a few months...this one doesnt. To me it is the best available sensor for any largers scale esp/iot/arduino project.

    Works Great

    Worked first time.

    Nice compact sensor unit

    This is a nice compact sensor unit with a simple connection. When paired with the ATOM lite controller, a small wireless sensor can be created very quickly.

    Very easy to implement into your project.

    Have been using these in a small batch of air quality handheld devices that I am producing, they work and mount easily in the project, only thing of note is that you may need to calibrate the output a tiny bit as i've noticed slight differences in readings in multiple sensors placed right next to each other, easy to take care of however. they will slightly increase temperature until they stabalize, prob 3 to 4 minutes. If you include a way to add or subtract a few degrees to the final output, you'll be very happy with it.


    Very good sensors
