MQ-7 Semiconductor Sensor for Carbon Monoxide

MQ-7 Semiconductor Sensor for Carbon Monoxide Sensitive material of MQ-7 gas sensor is SnO 2, which with lower conductivity in clean air. It make detection by method of cycle high and low temperature, and detect CO when low temperature (heated by ). The sensor’s conductivity is more higher along with the gas concentration rising. When high temperature (heated by ), it cleans the ...

MQ-7 Carbon Monoxide Sensor Circuit Built with an Arduino

The carbon monoxide sensor we will use is the MQ-7 sensor. This is a sensor that is sensitive to effects of CO. Carbon monoxide (CO) is a very dangerous gas which is odorless, colorless, and tasteless, so it cannot be smelt, seen, or tasted. A person really would have no idea that they are breathing in CO besides the fact that they would start to feel horrible. The most common symptoms of …
