MUMBAI, India, Feb. 6 -- Intellectual Property India has published a patent application (202541122323 A) filed by Nandha Engineering College, Erode, Tamil Nadu, on Dec. 5, 2025, for 'crop monitoring system using iot.'
Inventor(s) include E. K. Arulkarthick; K. Dhanush; T. Bhupesh Karthik; and A. Karthikeyan.
The application for the patent was published on Feb. 6, under issue no. 06/2026.
According to the abstract released by the Intellectual Property India: "The present invention discloses an intelligent, loT-enabled irrigation system designed to provide precise, automated and remotely controllable water management for agricultural applications. The system integrates an ESP32 microcontroller with multiple environmental sensors, including a soil moisture sensor, a temperature and humidity sensor (OJ-IT I I), a real-time clock (RTC) module and a water flow sensor. These sensors continuously monitor critical parameters such as soil moisture levels, ambieill temperature, humidity and real-time water flow, enabling the system to make accurate and timely irrigation decisions. The ESP32 processes the collected data and automatically actuates a relay-operated water pump when the soil moisture falls below a predetermined threshold or when a user-configured schedule is triggered. Flow sensor feedback ensures that water delivery is verified during pump operation, enabling the system to detect dryrun conditions, pipeline leakage or motor malfunction, thereby enhancing operational safety and reliability. A dedicated server hosts a web-based dashboard that provides real-time visibility of all sensor readings and pump status. Through this dashboard, users can remotely control the irrigation pump, modifY thresholds, adjust configurations and set precise irrigation schedules. Communication between the ESP32 and the server is established using Wi-Fi, enabling seamless dala ex hauge and long-distance accessibility. Ngrok is used to securely expose the server interface over the internet, allowing users to operate the system from any location without requiring static TP or port forwarding. The integration of automated decision-making, multi-parameter sensing, remote control functionality and tlow verification results in a highly efficient irrigation solution that significantly reduces water wastage, minimizes manual labour and ensures optimal watering cycles based on real-time field conditions. The invention provides a comprehensive, scalable and reliable system suitable for a wide range of applications, including agricultural fields, plantations, nurseries, greenhouses and smart farming environments. By enabling smart management of water resources through continuous monitoring and automated responses, the system contributes to improved crop health, enhanced operational convenience and sustainable agricultural practices."
