MQ131 sensing ozone gas detection module, the ozone gas with high sensitivity (detection concentration range 10PPB-1000ppb(1ppm), with the signal output indicator;, Main chip: LM393, MQ-131 gas sensor probe, ), Discounted price Aftermarket Worry-free Makes Shopping Easy Flagship quality, low price, free delivery.
Jul 05, 2020· If the gas concentration is high, the resistance decreases, and if the gas concentration is low, the resistance increases. The MQ-135 gas sensor basically needs only one key component as the external component – just a load resistor. The load resistor serves to …
MQ131 Ozone Gas Sensor (Low Concentration) Profile Sensitive material of MQ131 gas sensor is WO 3, which with lower conductivity in clean air. When the ozone gas exists, the sensor’s conductivity gets lower along with the gas concentration rising. Users can convert the change of conductivity to correspond output

The MQ131 ozone gas sensor is capable of sensing ozone air concentration levels between 10ppm and 1000ppm. The ideal sensing condition for the MQ131 is 20°C ±2°C at 65% ±5% humidity. An internal preheater inside the sensor helps achieve the ideal sensing conditions, but the datasheet recommends over 24 hours for preheating to achieve ...
Ozone 2 click is an Ozone detection (O 3) sensor, based on the MQ131 gas gas sensor has a sensitive layer made of SnO 2, which changes its resistance when exposed to sensor is able to sense O 3 concentration in the range of 10 ppm to 1000 ppm. The Click board™ is also equipped with a trimmer potentiometer, used to adjust the sensitivity and offset of the MQ131 sensor.
Sensitive material of the MQ131 gas sensor is O3 SnO2, which with lower conductivity in clean air. When Ozone gas exists. The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electro circuit, Convert change of conductivity to correspond output signal of gas concentration.
