Carbon Monoxide sensor module for Arduino and other microcontroler projects

This module has a sensitive Carbon Monoxide sensor that will detect levels of CO in normal air conditions. The resistance of the sensor changes with CO levels and will give you a varying voltage on the analogue pin and it has a comparitor to give you a digital out at when the CO level reaches a certain level, this can be set with the built in potentiometer.
Please note, this sensor needs to run for 24-48 hours before using it for the first time.
Voltage : 5VDC
Current : 100mA
Sensitivity : 10 to 10000ppm
