Package Includes: 1 piece x MQ 3 Alcohol Gas Sensor
MQ3 GAS Sensor is a very easy to use and very handy sensor. It is suitable for sensing Alcohol gas concentration. MQ3 Alcohol GAS Sensor can detect Alcohol gas concentrations anywhere from 200 to 10000 ppm. The MQ3 GAS sensor has a very hight sensitivity to Alcohol gas. The sensitive material of MQ3 sensor is SnO2, which has lower conductivity in clean air. When the target alcohol gas exist, the sensor’s conductivity is higher along with the gas concentration rising. MQ3 GAS sensor has high sensitivity to Alcohol, and good resistance to disturb of gasoline, smoke and vapour. The sensor could be used to detect alcohol with different concentration, it is with low cost and suitable for different application.
MQ-3 Sensor is suitable for detecting Alcohol, Benzine, CH4, Hexane, LPG, CO. Sensitive material of MQ-3 gas sensor is SnO2, which with lower conductivity in clean air. When the target alcohol gas exist, the sensor’s conductivity is more higher along with the gas concentration rising. MQ-3 gas sensor has high sensitity to Alcohol, and has good resistance to disturb of gasoline, smoke and vapor.
This sensor provides an analog resistive output based on alcohol concentration. When the alcohol gas exist, the sensor’s conductivity gets higher along with the gas concentration rising.
There is a resistance across an A and B inside the sensor which varies on detection of alcohol. More the alcohol, the lower the resistance. The alcohol is measured by measuring this resistance. The sensor and load resistor form a voltage divider, and the lower the sensor resistance, the higher the voltage reading will be.
High Sensitivity to Alcohol & small sensitivity to Benzine.
