ACEIRMC 5pcs MQ-3 MQ3 Alcohol Sensor Module Breath Gas Detector Ethanol Detection Module for Arduino Raspberry Pi ESP8266 MQ3 5V DC (MQ-3)
- Sensitive material MQ-3 gas sensor is used in clean air low conductivity tin oxide (SnO2)..
- When there is alcohol vapor in the environment sensor, conductivity sensor with increasing gas concentration of alcohol in the air increases.
- Use simple circuit can convert the change in conductivity of the gas concentration corresponding to the output signal..
- High MQ-3 gas sensor sensitivity to alcohol, can resist the interference of gasoline, smoke, water vapor..
- The MQ-3 sensor can detect a variety of alcohol concentration in the atmosphere, is a low-cost sensor suitable for a variety of applications.
