MQ-7 is used for sensing CO concentrations in the air. The MQ-7 can detect CO levels ranging from 10 to 500 parts per million. This sensor has high sensitivity and a fast response time. The output of the sensor is an analog resistance. The sensor works in temperatures ranging from -10 to 50°C and consumes less than 150 mA at 5 V. Both digital and analog outputs are available on this module. The threshold level for digital output can be easily adjusted using the preset on the board. The MQ-7 sensor module can be easily interfaced with microcontrollers, Arduino, etc. The sensor could detect different gases containing CO; it is a low-cost module suitable for various applications. When the module is powered with 5V, the power LED should glow, and when no gas is detected, the output LED will remain off, indicating that the digital output pin will be 0V. Its made in India
