CARBON MONOXIDE DETECTOR


Posted on Feb 6, 2014

This circuit has a focused optical sensor to transmit light to the CO reagent, and then sense the amount of light reflected. The reagent for CO detection darkens from a light yellow color when exposed to CO. According to the card`s manufacturer, a concentration as low as 100 parts per million (ppm) will darken the detector after 15 to 45 min. A concentration..
