Feb 09, 2012 Dear SirMa, It's my pleasure to use this opportunity to thank you for the roles you play in raising the standard of humanity. I am a graduate student working on Air Pollution Monitoring and Measurement using 'alphasensor COBF' and 'MQ131 ozone sensor which we integrated into our Air Pollution Monitoring System. MD131 datasheet, cross reference, circuit and application notes in pdf format. mq131 pdf TECHNICAL DATA. MQ131 GAS SENSOR FEATURES Fast response and High sensitivity Stable and long life Simple drive circuit Wide detecting range APPLICATION
Sensitive material of MQ131 gas sensor is WO3, which with lower conductivity in clean air. When the ozone gas exists, the sensors conductivity gets lower along with the gas concentration rising. Users can convert the change of conductivity to correspond output signal of mq131 pdf The MQ135 Gas sensors are used in air quality control equipments and are suitable for detecting or measuring of NH3, NOx, Alcohol, Benzene, Smoke, CO2. TECHNICAL DATA MQ7 GAS SENSOR FEATURES High sensitivity to carbon monoxide Stable and long life APPLICATION They are used in gas detecting equipment for carbon monoxide(CO) in family and industry or car. SPECIFICATIONS A. Standard work condition Symbol Parameter name Technical condition Remark MQ131 Test Circuit Instructions: The above fig is the basic test circuit of MQ131. The sensor requires two voltage inputs: heater voltage (V H) and circuit voltage (V C). V H is used to supply standard working temperature to the sensor and it can adopt DC or AC power, MQ131 Semiconductor Sensor for Ozone Sensitive material of MQ131 gas sensor is SnO 2, which with lower conductivity in clean air. When Ozone gas exists. The sensors conductivity is more higher along with the gas concentration rising.Rating: 4.51 / Views: 340
