How mq3 sensor works
WebMQ3 Alcohol Gas Sensor detects the concentrations of alcohol gas in the air and ouputs its reading as an analog voltage. The sensor can measure concentrations of 0.04mg/L to 4mg/L. The concentration sensing range is suitable for breathalyzers. The sensor can operate at temperatures from -10 to 50°C and consumes less than 150 mA at 5 V. Web2 jul. 2024 · MQ-3 Alcohol Sensor is base the amount ethanol molecules that is present near the electrodes. Therefore minimum and maximum distance had no or little bearing.
