Oh so good - by Richard

As a digi tech teacher, I use Mindkits for various classroom resources. I also have my Ultimaker serviced there and receive quality 3D printing advice when I need it. The office staff are quick to respond and very helpful.

Jase went out of his way to come to our home on a weekend to service our 3D printer and give our son tips on how to best use his 3D printer. Love the commitment, responsiveness and excellent knowledge.

Description
Reviews (0)

The MQ-137 is an Ammonia (NH₃) gas sensor from Winsen. The sensing element is SnO2, which has lower conductivity in clean air. When NH₃ (Ammonia) gas exists, the sensor’s conductivity gets higher along with the gas concentration rising. A simple circuit makes measuring this change in conductivity and turning it into data fairly straight-forward, but does require some calibration.

For easy Solderability; use our Gas Sensor Breakout Board.
