IOT Air Quality Node

Develop an IOT device that monitors the indoor air quality and notifies the users of the air quality level It includes a interactive dashboard implemented using Node-RED.

Currently the first prototype is created with a TVOC and CO2 sensor, Temperature and Humidity sensor and a Dust sensor.

Components used 💾

• ESP32 (Micro Controller)
• Plantower PMS7003 (Dust Sensor)
• DHT22 (Temperature and Humidity Sensor)
• SGP30 (TVOC and CO2 Sensor)

System Architecture 🔩

The prototype uses the ESP32 microcontroller and the above sensors to take measurements of air quality. These measurements are then sent to a server using the MQTT protocol under seperate topics. These readings are displayed on a Node-Red dashboard that subcribes to these topics and the data is shown in charts

Future improvements ✨

• Develop a PCB for the embedded device and develop the GUI interface further to make it more appealing and easthetic
• Develop a machine learning model to analyze the data acquired from the sensors and predict further trends and inferences
• Develop the system to integrate multiple nodes
