Carbon-monoxide detector relay switch. | Electronics Forums

Mar 31, 2010· Let me say it again: If you use the output of a standard home CO detector available in the USA to turn on a fan (instead of a buzzer) to ventilate an area, you MAY be too late. If you build you own detector using a raw sensor, you can set the threshold at which the FAN starts to be lower, which i think MAY be necessary for your safety. But if you use the same threshold to turn on an alarm as ...
