Design and Development of Website for Agricultural Field and Factory

The paper describe their work on developing a centralized monitoring system utilizing IoT technology for agricultural fields along with factory environments. The system acquires live sensor data from various ESP32-controlled devices that include Adafruit AHT20 (high-precision but low-cost temperature and humidity sensor) temperature and humidity modules and MQ-2 (metal oxide semiconductor type gas sensor) along with MiCS-5524 (Metal Oxide Sensor) gas detectors and ACS712 (Hall Effect-Based Linear Current Sensor IC) current analyzers and PZEM-004T (AC Multifunction Electric Energy Metering Power Monitor) power sensors. A DC submersible pump runs through the operation of a relay module. The system broadcasts sensor data through HTTP (Hypertext Transfer Protocol) requests to Google Sheets and creates a custom visual IoT dashboard which uses HTML and CSS joined with JavaScript for display. The system uses Telegram for rapid critical alert notification. Through its unified monitoring approach this system allows both agricultural and industrial sectors to boost operational performance while decreasing human-based operations and delivering data-based decision capabilities. The system functions with real-time visualization and remotecontrol features and alert system notifications to provide cost-effective operations for modern smart infrastructure requirements.
