How It Works

The IoT-Based Environmental and Gas Sensing project integrates multiple advanced sensors with a microcontroller to monitor air quality in real time. At the heart of the system is the IndusBoard Coin V2 U1, a compact microcontroller board powered by a 3.3V-3.7V battery. This board orchestrates data collection from two primary sensing elements: the BME 690 U2, which measures general environmental parameters, and the MICS 6814 U3, which detects various gases. Once the sensor data is gathered by the IndusBoard Coin, it is processed locally and formatted for visual output. The round GC9A01 LCD screen (LCD1), connected via a 24-pin 0.5mm FPC ribbon cable, serves as the local graphical display, rendering real-time metrics, system status, and visual alerts for the user. Additionally, using a custom sketch developed in the Arduino IDE alongside required sensor and display libraries, the IndusBoard Coin connects to a local wireless network. This allows the device to transmit environmental data logs over the internet, enabling remote observation and continuous monitoring of air conditions from anywhere with network access.
