Ozone Sensor MQ131 Breakout

The MQ131-H is the high concentration version of the MQ131 ozone sensor, designed for detecting ozone (O₃) levels in the 10 - 1000 ppm range. This sensor offers good sensitivity to O₃ and operates on the semiconductor detection principle, making it well-suited for industrial and environmental applications. The MQ131 sensor's sensitivity and selectivity enable it to effectively detect and measure ozone levels, making it a valuable tool for applications such as air quality monitoring, ozone generators, and ozone leakage detection systems. By integrating the MQ131 sensor with appropriate electronic circuits and microcontrollers like NULA, you can create systems that provide real-time ozone concentration monitoring and trigger alerts when hazardous levels are detected. The breakout board works with both digital (DO) and analog signals (AO). The digital output is obtained by setting a threshold value with a potentiometer, while the analog output will vary depending on the intensity of the detected gas. Product usage tips:

• When gas is detected, the LED will light up. It will remain off if no gas is detected.
• The board includes two mounting holes for easy installation on surfaces.
• Four male headers are included but need to be soldered by the user.
