MQ-131 Ozone Gas Detection

Detail MQ-131 Ozone Gas Detection

Deskripsi Produk

Sensitive material of MQ131 gas sensor is SnO2, which with lower conductivity in clean air. When Ozone gas exists. The sensors conductivity is more higher along with the gas concentration rising. Please use simple electrocircuit, Convert change of conductivity to correspond output signal of gas concentration.
MQ131 gas sensor has high sensitity to Ozone, also sensitive to CL2, NO2, etc.

work voltage: DC 5V
with the signal output LED indication;
the dual signal output (analog output, and TTL level output);
TTL output valid signal is low; (low output signal light, which can be accessed microcontroller IO port)
analog output increases with the concentration, the higher the voltage the higher the concentration;
the ozone gas has a high sensitivity (detection concentration range 10PPB-2PPM)
with a long life and reliable stability;
Fast response characteristics;
with mounting holes for easy permanent installation;
the probe can plug design for easy testing.
for home and atmospheric environment ozone gas detection devices
