Arduino CO Monitor Using MQ7 Sensor : 8 Steps (with ...

But here''s the problem: Arduino can''t provide enough power to run this sensor from its pins sensor''s heater requires 150 mA, while Arduino pin can provide no more than 40 mA, so if attached directly, Arduino pin will burn and sensor still won''t work. So we must use some kind of current amplifier that takes small input current to control large output current.

Create Your Own CO Detector DigiKey

CO sensor prototype with an Arduino board. (Image courtesy of SPEC Sensors) So as a final example, with this setup we are measuring Volts. First subtract the zero voltage of V, giving V or 55 mV. Now divide by our new sensitivity of mV/ppm and we are measuring 240 ppm CO, which is a dangerous level to breath for long periods of time. Summary and next steps: By using the ...

CO (Carbon Monoxide) Gas Sensor Using the Arduino Uno

20140329· 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 …
