RobotDyn - Alcohol gas Sensor - MQ-3, for DIY projects Arduino, STM32, Raspberry (analog and digital out)




1 PC - Methane gas Sensor - MQ-4


1 PC - Carbon Monoxide (CO) gas sensor - MQ-7


1 PC - LP gas (Propane / Butane) Sensor - MQ-6

Product Description

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 900mA at 5V.

This sensor: 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.
