07/10/2018· MQ-3 Equivalent Sensors. MQ-2, MQ214 (detection of Methane), MQ303A . Brief Detail about MQ-3 Gas Sensor. MQ-3 module is suitable for detecting Alcohol, Benzine, CH 4, Hexane, LPG, material of MQ-3 gas sensor is SnO 2, which with lower conductivity in clean the target alcohol gas exist, the sensor’s conductivity is more higher along with the gas concentration rising.
04/06/2019· A gas sensor is a device which detects the presence or concentration of gases in the atmosphere. Based on the concentration of the gas the sensor produces a corresponding potential difference by changing the resistance of the material inside the sensor, which can be measured as output voltage. Based on this voltage value the type and ...
The MQ-2 smoke sensor is sensitive to smoke and to the following flammable gases: The resistance of the sensor is different depending on the type of the gas. The smoke sensor has a built-in potentiometer that allows you to adjust the sensor sensitivity according to how accurate you want to detect gas.
01/03/2018· This review paper encompasses a detailed study of semiconductor metal oxide (SMO) gas sensors. It provides for a detailed comparison of SMO gas sensors with other gas sensors, especially for ammonia gas sensing. Different parameters which affect the performance (sensitivity, selectivity and stability) of SMO gas sensors are discussed here under.
