From the project

Hardware design, BOM, gerbers and 3D files for Ammonia-sensor-MQ137-breakout designed by Soldered Electronics.

The MQ137 sensor’s sensitivity and selectivity allow it to effectively detect and measure ammonia levels, 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 takes a short time to heat up in order to work correctly.
