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.
