IoT Based Air Pollution/Quality Monitoring with ESP8266

· The MQ135 sensor is a signal output indicator instruction. It has two outputs: analog output and TTL output. The TTL output is low signal light that can be accessed through the IO ports on the Microcontroller. The analog output is an concentration, increasing voltage is directly proportional to increasing concentration. This sensor has a long life and reliable stability as well.

Interfacing MQ135 Gas Sensor with Arduino Electronics ...

· MQ135 is a gas sensor which is sensitive to CO2. The change in CO2 levels changes the resistance of sensor which results in the change in the output of the sensor. The output generated from the sensor is feed to Analog Input to Arduino board ( In my case Arduino Uno). The analog data is taken by ADC of Arduino, according to the voltage levels ...

MQ135 Arduino library | Details |

· The MQ811 is much more expensive (30 compared to 3). The datasheet claims that the MQ135 is sensitive for CO2, Alkohol, Benzene, NOx, NH3 and the Fig 3 shows the change in resistance depending on the concentration of these gases in the ambient air in ppm (of the total gas volume).

MQ135 Gas Sensor with Arduino Code and Circuit Diagram

· But, in this project, we will only play a buzzer. We will also include one red and one green LED. Circuit Diagram for MQ135 gas sensor. We are going to receive analog value from the sensor. We used the Arduino A5 pin. So we connected the A5 pin with the 4th pin in the sensor. The sensor GND and VCC goes to Arduino GND and 5volt.
