Carbon Monoxide sensor module for Arduino and other microcontroler projects

 
A Carbon Monoxide sensor detects CO in normal air conditions.
The resistance of the sensor changes with CO levels giving a varying voltage on the analogue pin. A comparator supplies a digital output when the CO level reaches a certain level, set with the built in potentiometer.
 
Please note, this sensor needs to run for 24-48 hours before first time use
 
Voltage : 5VDC
Current : 100mA
Sensitivity : 10 to 10000ppm
Size 32x21mm
