Product description: alcohol sensor MQ-3

The sensor determines the concentration of alcohol in the air, the result can be obtained measuring the voltage on the analog output. Through this device, the user can create their own breathalyzer. Sensor can be used, for example, in the module of Arduino or board from the family STM32 Discovery.

 

Measurement range from 0.04 mg/L to 4 mg/L, it allows you to use it as the breathalyzer

 

Ratio: 0.1 mg/L = 0,21‰.

 

Sensor MQ-3 can operate in the temperature range: -10-50°C and consumes no more than 150mA at 5V power supply. More information is contained in documentation of the sensor.
