IoT based Air Pollution Monitoring System using Arduino Circuit Diagram This project implements an air quality monitoring system using an ESP8266 WiFi module, various sensors, and the ThingSpeak platform. The system measures environmental parameters such as CO2, temperature, humidity, CO, LPG, and smoke levels, providing real-time data and insights into air quality. MQ135 Air Quality Sensor. The MQ-135 gas sensor senses the gases like ammonia nitrogen, oxygen, alcohols, aromatic compounds, sulfide and smoke.The MQ-3 gas sensor has a lower conductivity to clean the air as a gas sensing material. In the atmosphere, we can find polluting gases, but the conductivity of the gas sensor increases as the concentration of polluting gas increases.

It's vital to monitor air quality to protect our health and reduce pollution levels. One of the most effective ways to monitor air quality is by using an air quality monitoring system. In this blog, we will discuss how to create an air quality monitoring system using NodeMCU or ESP8266, DHT21, Dust Sensor, MQ2, MQ4, MQ9, and MQ135 sensors.

Testing and calibrating the sensor. The initial step involves calibrating the sensor. To achieve this, connect the sensor to the circuit and allow it to remain powered on for 24 hours to complete

An ESP8266 based air pollution detector is an easy and low cost way to create an air quality monitoring solution that is real time. In this comprehensive guide, we will go through step-by-step how to build a reliable air pollution detector using the ESP8266 Arduino NodeMCU and popular air quality sensors.

Creating Your Own Air Quality Monitoring System with ESP8266 Circuit Diagram
As concerns about air pollution grow globally, understanding and tracking air quality become paramount. This comprehensive guide will walk you through the step-by-step process of connecting the powerful SDS011 sensor with the versatile ESP8266, creating a cost-effective and efficient air quality monitoring system.
Overview. This is a simple prototype for an Environmental IoT Air Pollution/Quality Monitoring System for monitoring the concentrations of major air pollutant gases. The system uses 3 sensors like PMS5003 PM2.5 Particulate Matter Sensor, MQ-135 Air Quality Sensor, BME280 Barometric Pressure Sensor.In this IoT project, you can monitor the pollution level from anywhere using your computer or mobile.
