MQ-7 CO Sensor Hydrogen Response - SparkFun Electronics

2013-01-06· Perhaps you can locate and borrow a calibrated CO sensor, or generate a known concentration of CO chemically. For my H2 testing, I electrolyzed water and collected the liberated gas, filled a 25ml syringe and released that into a closed 30-gallon trash container with a small fan inside to mix it well. 25ml in 30 gallons is ~200ppm.

Discuss Tutorial: Hazardous Gas Monitor -

SparkFun ; Arduino ; Raspberry Pi ... When the CO gas sensor's heater needs to be in the 5V phase (turnHeaterHigh()), COVoltPin is low so the relay is off and stays on the NC pin. When the heater needs to be in the ~ phase, (turnHeaterLow()), COVoltPin is high so the relay is on and switches to the NO pin. Thus, the lines of code that use CORelayPin on D6 can be ignored or commented out ...
