Internet of Things: CO (Carbon Monoxide) Gas Sensor Using the …

29/03/2014· CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno This simple project uses the Arduino Uno and the MQ7 Gas Sensor to sense the concentration of CO (Carbon Monoxide) in the air. The MQ7 requires a heater voltage that cycles between 5v (60s) and (90s), drawing approximately 150mA at 5v which exceeds the power capacity of the Uno, so I use the KA278RA05C adjustable …

Arduino CO Monitor Using MQ-7 Sensor : 8 Steps (with Pictures ...

I highly recommend to find a calibrated CO meter, make 100 ppm CO sample (this can be done by taking some flue gas into syringe - CO concentration there can easily be in the range of several thousands ppm - and slowly putting it into closed jar with calibrated meter and MQ-7 sensor), take raw sensor reading at this concentration and put it into sensor_reading_100_ppm_CO variable. Without this step, your ppm …
