How the sensor works is the terminal AOUT gives an analog voltage output in proportion to the amount of carbon monoxide the sensor detects. The more CO it detects, the greater the analog voltage it will output. Conversely, the less CO it detects, the less analog voltage it will output. If the analog voltage reaches a certain threshold, it will send the digital pin DOUT high. Once this DOUT pin ...
Before selecting the voltage output, please consider: • The voltage output is derived from the digital output (it is a PWM driven) • A digital interface is required to configure the CO₂ sensor • Even if the end application will use only a voltage interface, SST recommend using a digital interface ( USB to serial cable) when evaluating the sensor
According to its datasheet, the MQ7 carbon monoxide sensor detects 20 to 2000 ppm of CO in air. Here is its sensitivity characteristic curve: This is a graph of Rs/R0 vs. gas concentration in ppm. Rs is the resistance of the sensor in target gas while R0 is the resistance in clean air.
The MQ7 carbon monoxide sensor is especially designed to be sensitive to carbon monoxide (CO) gas which is emitted by vehicles, factories, etc. Since this gas is considered toxic to humans at certain levels, concentration of CO is used to determine the air pollution in a given area.
