Methane gas sensor module for Arduino and other microcontroler projects

 
This module has a sensitive methane sensor that will detect levels of methane in the air. The sensor outputs a varying voltage on the analogue pin depending on the level of methane and it has a comparitor to give you a digital out at when the methane level reaches a certain level, this can be set with the built in potentiometer.
 
Please note, this sensor needs to warm up for 20 seconds before it will give a stable reading.
 
Voltage : 5VDC
Current : 150mA
Sensitivity : 300 to 10000ppm
Size 32x21mm
