MQ-7 Sensor Module
Carbon monoxide gas is a very dangerous, harmful, and toxic gas for the normal environment. Since the gas has no color and is odorless, so it cannot be smelt or seen. So, if there is carbon monoxide gas in the surroundings, the person really would get no idea that they are breathing in CO until he/she feels not safe. So, it is necessary to have detected that toxic gas. Hence, there is an MQ7 gas detector sensor that can detect this harmful gas. Below is the complete description of this sensor.
