MQ-3 MQ3 alcohol sensor, alcohol sensor, alcohol gas sensor

Product Description

MQ-3 MQ3 alcohol sensor, alcohol sensor, alcohol gas sensor

Descriptions:
– Sensitive material of MQ-3 gas sensor is SnO2, which with lower conductivity in clean air. When the target alcohol gas exist, The sensors 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.
– MQ-3 gas sensor has high sensitity to Alcohol, and has good resistance to disturb of gasoline, smoke and vapor. The sensor could be used to detect alcohol with different concentration, it is with low cost and suitable for different application

Character 
– Good sensitivity to alcohol gas 
– Long life and low cost 
– Simple drive circuit

Application 
– Vehicel alcohol detector
– Portable alcohol detector
