MUMBAI, India, Jan. 9 -- Intellectual Property India has published a patent application (202541133938 A) filed by Ifet College Of Engineering, Viluppuram, Tamil Nadu, on Dec. 31, 2025, for 'solar-powered sensor-based automatic irrigation monitoring and pump control system.'
Inventor(s) include Mrs. P. Pravina; Dr. B. Elizabeth Caroline; S. Vigneshwar; and E. Jayaprakash.
The application for the patent was published on Jan. 9, under issue no. 02/2026.
According to the abstract released by the Intellectual Property India: "An automatic irrigation system is disclosed, comprising a solar panel [102] configured to collect solar energy, a rechargeable battery [104] operatively coupled to store the collected energy, and a microcontroller unit [106] powered by the rechargeable battery [104]. A soil moisture sensor [108] is operatively coupled to the microcontroller unit [106] to provide a soil moisture level. A pumping arrangement comprising a pumping motor [114] and a water pump unit [116] is operatively controlled by the microcontroller unit [106], wherein the microcontroller unit [106] activates the pumping arrangement when the soil moisture level falls below a preset threshold and switches off the pumping arrangement when the soil moisture level is restored to the preset threshold level, thereby reducing excess watering and water wastage. In an optional configuration, a temperature sensor [110] and a light sensor [112] support irrigation scheduling based on climatic variation and reduced evaporation."
