Abstract

• Cloud based real-time air quality and environmental parameters monitoring and logging system is based on the internet of things (IoT) using the ESP32 board which can process sensor data and upload them to cloud via internet. The system is based on MQTT protocol using ESP32, BME680 integrated environmental sensor, BH1750 light intensity sensor and UV sensor. The readings from all sensors are processed by the ESP32 board and uploaded to the ThingSpeak cloud. The real-time parameters are also displayed on the TFT LCD as well as serial monitor. The data collected in ThingSpeak cloud can be exported in .csv format. This research highlights the benefits of the advanced cloud-based technology which effectively reduce time and energy waste for human labor.
