29/3/2014· When this pin is low it turns off the relay causing the regulator to go back up to 5v. Analog pin 0 on the Arduino Uno is used to sense the voltage level out of the MQ7 which serves to measure the concentration of CO (Carbon Monoxide) in the air. Below is the diagram of the circuit on Fritzing.
The other 2 leads are AOUT (analog output) and DOUT (digital output). 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.
5/5/2021· You are supposed to use a known CO reference to calibrate your sensor. If you just want a VERY ROUGH value, the graphs in the datasheet tend to indicate that when the resistance drops to 1/28th the resistance in clean air you probably have about 100ppm and …

Gravity analogue Carbon Monoxide Sensor (MQ7) For Arduino It uses MQ7 probe to detect Carbon Monoxide (CO) concentrations in the air from 20 to 2000ppm. The sensitivity can be adjusted by the potentiometer. The output is proportional to the density of gas. You can use analogue reading to read the data from this sensor.
Carbon dioxide has a very strong absorption band between 4200 nm and 4320 nm, as shown in Figure 4. Figure 4. Absorption spectrum of carbon dioxide (CO2). The available output range of IR sources and the absorption spectrum of water also govern the choice of the sensing wavelengths.
The circuit shown in Figure 1 is a complete thermopilebased gas sensor using the NDIR principle. This circuit is optimized for CO2 sensing, but can also accurately measure the concentration of a large number of gases by using thermopiles with different optical filters.
