MUMBAI, India, May 1 -- Intellectual Property India has published a patent application (202641049580 A) filed by Seshadri Rao Gudlavalleru Engineering College; Dr. D. Prabhakar; Dr. T. Subhashini; O. Deva Nandini; P. Devika; Md. Vaseem Khadhar; and T. Naga Akash Kumar, Gudlavalleru, Andhra Pradesh, on April 18, for 'smart aquatic farming: an iot system for monitoring and managing aquaculture tanks.'
Inventor(s) include Seshadri Rao Gudlavalleru Engineering College; Dr. D. Prabhakar; Dr. T. Subhashini; O. Deva Nandini; P. Devika; Md. Vaseem Khadhar; and T. Naga Akash Kumar.
The application for the patent was published on May 1, under issue no. 18/2026.
According to the abstract released by the Intellectual Property India: "The Internet of Things (IoT) enables real-time monitoring and automation through interconnected devices. This project presents an IoT-based smart aquaculture monitoring system designed to overcome the limitations of traditional fish farming, such as manual supervision, water pollution, and fish mortality. The system continuously monitors key water quality parameters including ammonia (MQ137), salinity (TDS/EC), and decomposition gases (MQ3/MQ135 or ORP sensors), along with environmental conditions like temperature, humidity, air quality, pressure, rainfall, and lightning. All sensor data is processed by a Raspberry Pi for real-time decision-making. A major highlight of the system is hunger detection, which uses motion sensing (FC-51) to analyze fish activity patterns and estimate feeding needs. This helps optimize feeding schedules, reduce feed wastage, and prevent water contamination caused by overfeeding. Based on sensor readings, the system automatically activates pumps, dosing mechanisms, or alert systems to maintain optimal conditions. This fully automated, camera-free solution improves efficiency, reduces labour, and enhances sustainability and productivity in aquaculture operations. Keywords: Ammonia, Air Quality, Salinity, Temperature and Humidity, Rainfall, lightening, Atmospheric pressure, Hunger detection."
