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.
MQ7 sensor has an acute sensitivity to Carbon Monoxide and can detect the concentration of carbon monoxide in the surroundings. MQ7 sensor has a small heater inside with an electrochemical sensor to measure different kinds of gas combinations. Thus, it can be calibrated. We can use the gas sensor module at room temperature.
The ability of an MQ7 Gas sensor depends on the chemiresister. The chemiresistor is Tin Dioxide (SnO2) which that has free electrons (donors). The oxygen molecules attract the free electrons present in a tin dioxide that pushes them to the surface of the tin dioxide. When there are no free electrons available output current would be zero. The oxygen molecules attract the free electrons inside the tin dioxide (SnO2) and prevent it from having free electrons to conduct current.
Features
The analog output voltage, the higher the concentration the higher the voltage.
The carbon monoxide detection with better sensitivity.
With a long service life and reliable stability.
Rapid response and recovery characteristics
