mq2 gas sensor with lcd

MQ135 Gas Sensor with ESP8266 and LCD Display with I2C ...

MQ135 gas sensor works on analogue and digital pins with Arduino boards. It gives analogue value in PPM of Air Quality. When we use a digital pin, it gives on signal at a particular value of analogue. This can be adjusted via potentiometer. So, you can also detect a particular gas without using any micro controller. Just seeing a green LED, you can know it.
