Carbon Monoxide gas sensor module for Arduino MQ-7

---

Carbon Monoxide sensor module for Arduino and other microcontroller 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
