Henan Hanwei Electronics Co., Ltd www.hwsensor.com MQ131 Semiconductor Sensor for Ozone Sensitive material of MQ131 gas sensor is 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 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. Character * Good sensitivity to Ozone in wide range * High sensitivity to Ozone * Long life and low cost * Simple drive circuit Application * Domestic Ozone concentration overload Detector * Industrial Ozone concentration overload Detector * Portable Ozone concentration overload Detector Configuration Technical Dat [ ... ]
