The MQ-7 is a carbon monoxide (CO) gas sensor module that can be used to detect the presence of CO gas in the air. The module uses a metal oxide semiconductor (MOS) to detect CO gas, which is a toxic gas that is produced by the incomplete burning of fossil fuels. The MQ-7 can be used in a variety of applications, including in home security systems, gas leak detectors, and portable gas detectors. The module has a simple analog output that can be read by a microcontroller or other control system, and it can operate over a wide range of temperatures and humidity levels. The sensitivity of the MQ-7 can be adjusted by changing the resistance of a potentiometer on the module.
Use the MQ7 module with your Arduino to easily detect Carbon Monoxide (CO) gas.
