333107 Developer boards - gas sensor, carbon monoxide, MQ-7

The MQ7 sensor has a high sensitivity and selectivity, which enables it to effectively detect and measure carbon monoxide concentrations.

This makes it an important tool for applications such as gas leak detection, safety systems and environmental monitoring. By interfacing the MQ7 sensor with suitable electronic circuits and microcontrollers such as Arduino (or a compatible board such as Dasduino), systems can be created that enable real-time monitoring and provide prompt alerts in the event of dangerous CO concentrations. It is necessary that the sensor needs some time to warm up in order to function correctly.

The breakout board works with both digital (DO) and analog (AO) signals. The digital output signal is obtained by setting a threshold value with a potentiometer. The analog output signal depends on the intensity of the gas.
