This project is about the development of a smart dust monitoring system that is also equipped with IoT Cloud. As dust is crucial to the health of the people, it is important to monitor the dust level and to get alerts if the dust level exceeds the healthy range. With the inclusion of IoT Cloud, the ability to remotely monitor the dust level, sending out alerts and having historical data further enhance the capabilities of the system. For this project, a system was developed using an ESP32, dust sensor and ThingSpeak as the IoT Cloud platform. Every reading taken would be transmitted to the ThingSpeak channel where you can monitor the dust level and view historical data. If dust level exceeds the threshold, an alert will be sent out. For power efficiency, a dynamic sampling rate is implemented to control the system’s timer for its deep sleep mode where most of its functions will be shut down while saving some states on its RAM to reduce its energy consumption. Through this report, I will be sharing my hands-on experience with designing and developing a micro-controller-based system with IoT Cloud.
