MQ-3 Alcohol decector sensor Module
The sensor has a high sensitivity to alcohol vapors (SnO2), and fast response time.
The sensor can measure low concentrations of alcohol vapor in the air. The sensor may operate at temperatures ranging from -10 to 50 ° C and consumes about 700mA at 5V.
There are two modifications of the sensor:
Standard - with sensitivity.
With analog and digital outputs - sensor has 2 outputs: digital output is a certain level of gas concentration, or analog output, which gives the actual value of the hydrogen concentration. Sensitivity can be adjusted by a potentiometer.
The sensitivity of the alcohol concentration from 25 ppm (part per million) to 500 ppm.
Operating temperature range from -10 to 50 ° C.
Power 900mA at 5V.
