SainSmart MQ131 Ozone Gas Detection Sensor Module

* with the signal light indicates the output;
* the dual signal output (analog output, and TTL-level output);
* TTL output valid signal is low; (low output signal light, can be accessed by the microcontroller IO port)
* the analog output increases with the concentration, the higher the voltage the higher the concentration;
* the ozone gas with high sensitivity (detection concentration range 10PPB-2PPM Ozone)
* with a long life and reliable stability;
* Fast response characteristics;
* with mounting holes to facilitate fixed installation;
* the probe can plug design for easy testing.
