Description

The sensitivity and selectivity of the MQ137 sensor allow it to effectively detect and measure levels of ammonia, making it a valuable tool for applications such as gas leakage detection, agricultural monitoring, and environmental sensing. By integrating the MQ137 sensor with appropriate electronic circuits and microcontrollers like Dasduino, you can create systems that provide real-time monitoring and prompt alerts in the presence of hazardous ammonia concentrations. It requires a short time to heat up in order to work correctly.

The breakout board provides digital and analog information through the Qwiic system. Sensor readings are obtained through Qwiic.

Product usage tips:

When gas is detected, the LED will start glowing. It will remain off if it doesn't detect anything. Four mounting holes enable easy mounting to surfaces. The board comes with three male headers.

I picked up the MQ137 breakout board for an environmental monitoring setup in my greenhouse, and overall it works really well. Integrating it with my Dasduino via Qwiic was super smooth, and getting sensor readings couldn't be easier. The gas detection LED indicator is a great visual cue, and the four mounting holes made installation painless. My only minor complaint is that you have to wait a little bit for the sensor to heat up before it gives accurate readings, but once it warms up, performance is rock solid. Definitely recommended!
