ABSTRACT:
Described is a system for measuring noxious gas concentration in an affected space and for controlling the device producing the noxious gas or for decreasing the concentration of the gas in the affected space. The invention is particularly described in relation to measuring carbon monoxide concentration in an automobile garage and for controlling the garage door opener circuit to open the garage door in response to a preselected concentration of carbon monoxide. Also described in particular is a system for deactivating a furnace operating circuit to turn off the furnace in the event of excessive carbon monoxide concentration.
