ESP8266 WiFi Temp Humidity Monitoring Web App Using Arduino IDE 7 Circuit Diagram 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. Once your data is stored in InfluxDB, you can use visualization tools like Grafana to create real-time dashboards. This will allow you to monitor your air quality, temperature, and humidity trends. Conclusion. With ESP8266 version 3.0.2 and InfluxDBClient version 3.13.2, you can reliably build an IoT system for air quality monitoring. This

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.
