Where should I place a carbon monoxide detector? | US EPA

Jul 01, 2021· The detector may be placed on the ceiling. Do not place the detector right next to or over a fireplace or flame-producing appliance. Keep the detector out of the way of pets and children. Each floor needs a separate detector. If you are getting a single carbon monoxide detector, place it near the sleeping area and make certain the alarm is loud ...

Alkaline batteries versus zinc batteries: differences >>

An overview below. The main difference between a zinc battery and an alkaline battery is the type of electrolyte used in both batteries. Zinc batteries are mostly composed of ammonium chloride while the alkaline batteries use potassium hydroxide. However, these technical specifications don't say much more about the usage of the batteries.

Gas Sensors Carbon Monoxide (CO) -

Carbon monoxide is a colorless, odorless, toxic gas. It is predominately produced by incomplete combustion of carbon-containing materials. Incomplete combustion occurs when insufficient oxygen is used in the fuel (hydrocarbon) burning process. Consequently, more carbon monoxide than carbon dioxide is emitted.
