The emission of carbon monoxide from automobiles, industrialism, direct or indirect smoking, and poorly ventilated appliances like gas heaters or space heaters has gigantic effects on our lives. More specifically, during the cold winters, people tend to stay warm in their blankets with the constant heat from heaters. As comforting and welcoming the heat may feel, the heaters in fact release a much more dangerous product, which is quite unknown amongst the common folks. Carbon monoxide is a deadly gas which directly affects our internal system and causes numerous health problems. It is released through appliances like the heaters and can lead to allergies, dry skin, sleepless nights, and breathing problems, in fact, if being kept in contact with it for too long, it can even cause death in the most suffocating manner. The risk of death gets higher, as it meddles with the blood travel to the brain leading to brain haemorrhage. In order to solve the recurring deaths because of this, we have found a solution to this problem. We have designed a carbon monoxide detector with automatic ventilation. This invention alarms us when the levels of CO increase in the room and automatically opens a ventilation to let it out. This is a new step towards a safer, guarded, and a very comfortable life for those in contact with CO on a daily basis
