The MQ131 sensor is characterized by its sensitivity and selectivity, which makes it an effective tool for the detection and measurement of ozone. This is particularly relevant for air quality monitoring, ozone generators and ozone leak detection systems. Integrating the MQ131 sensor with an Arduino (or a compatible board such as Dasduino) enables the creation of systems that provide real-time monitoring of ozone concentration and trigger alarms when dangerous levels are reached. https://elecena.pl/product/25847773/333110-developer-boards-gas-sensor-ozone-o3-mq-131 2024-05-11 https://elecena.pl/product/25847773/333110-developer-boards-gas-sensor-ozone-o3-mq-131 2025-09-04
