The MQ-7 gas sensor is a device that can detect the presence of carbon monoxide (CO) gas in the air. It is commonly used in applications such as gas leak detectors, safety devices, and industrial control systems. The MQ-7 sensor operates by using a chemical reaction between the CO gas and a conductive metal oxide to produce a current. The magnitude of the current is proportional to the concentration of CO gas in the air. The sensor can be used to detect CO gas concentrations in the range of 20-2000 ppm.
It is important to note that CO is a poisonous gas that can be dangerous at high concentrations. It is recommended to use the MQ-7 gas sensor with caution and to take appropriate safety measures when working with it. The MQ-7 can detect CO-gas concentrations anywhere from 20 to 2000ppm. This sensor has a high sensitivity and fast response time. The sensor’s output is an analog resistance.
I recently installed the MQ-7 gas sensor in my home and it has been a great addition to my safety measures. It allows me to quickly detect any carbon monoxide gas leaks that may occur and take appropriate action. It was also easy to install and has been very reliable. I would definitely recommend it to other homeowners.

Compact and accurate gas detector
I purchased the MQ-7 gas sensor for use in a portable gas leak detector that I built and it has been working great. It was easy to install and has been very accurate in detecting even small amounts of carbon monoxide gas. The sensor is also compact, making it easy to incorporate into my device. I'm happy with my purchase.

Essential safety tool in the workplace
We've been using the MQ-7 gas sensor in our factory for a few months now and it has been a crucial addition to our safety measures. It allows us to quickly detect any carbon monoxide gas leaks that may occur and shut down equipment before any accidents happen. It has been very reliable and easy to use. We would definitely recommend it to other industrial facilities.
