MQ-131 Low concentration ozone gas detection sensor module

Description

Description

with the signal output indicator;
dual signal output (analog output, and TTL level output);
TTL output valid signal is low; (output low signal light, which can be accessed microcontroller IO port)
analog output increases with the concentration, the higher the concentration the higher the voltage;
the ozone gas with high sensitivity (detection concentration range 10PPB-2PPM)
with a long service life and reliable stability;
rapid response and recovery characteristics;
with mounting holes to facilitate fixed installation.
