Carbon monoxide (CO) poisoning is a public health problem. Because CO is a colorless and
odorless gas, with its affinity to hemoglobin 240 times more than oxygen’s, poisoning accidents
frequently result from incomplete indoor combustion. For example, an improperly vented natural gas
heater in a small room can make the air unsafe to breathe within a few minutes. The aim of this
research is to apply a system to react to the presence of CO in the environment. CO sensors are used to
detect indoor CO concentrations and a CPU is used to process signals and to activate a voice chip, an
LED chip, a message chip and a wireless module. The Wireless Fidelity (Wi-Fi), Bluetooth, a
small-power wireless network protocol (Zigbee) or Ultra WideBand (UWB), will transmit the signals to
the receptor of a negative-pressure ventilator. This improved device is expected to reduce the number
of cases of CO poisoning.
