Air Quality Supervision System using the IoT Platform

Abstract

This paper presents the idea of the Internet of Things (IoT) platform, which is demonstrated by creating a device that measures air quality, collects and processes realtime data, and presents it in a web application. The device comprises a microcontroller board called Wemos D1 Mini, which is powered by an ESP8266 microchip. It also consists of two sensors, CCS811, which measures air particle quantity, and BME280, which measures air temperature, pressure, and humidity. The device is wirelessly connected to an MQTT broker using a Wi-Fi network and the MQTT protocol. The paper also provides detailed information on the functioning and usage of the MQTT protocol along with guidelines for programming and configuring the MQTT broker for both Wemos D1 and Raspberry Pi.
