Description
Combustible gas and smoke sensor module for Arduino and other microcontroller projects
This module has a sensitive gas sensor that can measure smoke and various combustible gases. It can measure compunds such as LPG, Propane, Methane and smoke. The sensor outputs a varying voltage on the analogue pin depending on the level of gases present and it has a comparator to give you a digital output when the level of combustible gases reaches a certain level. This can be set with the built-in potentiometer.
Please note, this sensor needs to warm up for a couple of minutes before it will give a stable reading.
Voltage : 5VDC
Current : 150mA
Sensitivity : 300 to 10000ppm
Size 32x21mm
