Product description
Ozone sensor based on the MQ131-H for detecting ozone (O₃) gas. The module is suitable for air quality monitoring and systems for detecting ozone levels or ozone leaks. It can be used with a microcontroller to measure ozone concentration and generate alarms when elevated levels are detected.
The MQ131-H is the high-concentration version of the MQ131 and is designed for measuring ozone concentrations from 10 to 1000 ppb. The module provides both analog (AO) and digital (DO) outputs. The digital output is activated when an adjustable threshold is exceeded, while the analog output varies according to the ozone concentration. An onboard LED indicates when gas is detected. Two mounting holes make the module easy to install, and it is supplied with a pin header (not pre-soldered).
