MQ7 Carbon Monoxide Sensor Circuit Built with an Arduino

+

Carbon monoxide poisoning is the most common type of fatal air poisoning in many countries. Being colorless, odorless, and tasteless, it is very hard to detect but highly toxic. Carbon monoxide is absorbed through breathing and enters the bloodstream through gas exchange in the lungs. CO combines with hemoglobin to produce carboxyhemoglobin, which usurps the space in hemoglobin that normally ...
