Feature
The sensor has a high sensitivity to alcohol vapors (SnO2), and faster 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.
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.
Package includes
20 x Gas Sensor Module
