MUMBAI, India, Aug. 12 -- Intellectual Property India has published a patent application (202641091490 A) filed by Psna College Of Engineering And Technology on July 28, 2026, for Iot - Enabled Brine Salinity Monitoring Device With Mobile Alert Feature For Salt Harvesting.
Inventors include C. Preethi; A. Janani; and S. Gowri.
The application for the patent was published on August 07, 2026, under issue no. 32/2026.
Abstract: The invention describes a wireless salt-level sensor designed for installation on a water softener tank to continuously monitor the amount of salt available. The system uses a laser or ultrasonic distance sensor to accurately measure the salt level without direct contact. The collected data is transmitted through a Wi-Fi communication module to a smartphone application, allowing users to remotely monitor the salt level in real time. The system generates notifications when the salt level falls below a 15 predefined threshold, enabling timely refilling and preventing interruption in the water softening process. The invention is designed as a low-cost, easy-to-install, and user-friendly solution that improves maintenance efficiency and reduces manual inspection. Additionally, the system supports cloud-based data storage for maintaining historical salt-level records and usage patterns. It enables users to monitor multiple water softener units through a single mobile application. The wireless 20 communication ensures continuous data synchronization and remote accessibility. The modular design allows quick installation without significant modification to existing water softener systems. Overall, the invention provides a reliable, efficient, and smart IoT-based solution for monitoring salt levels and improving the performance of water softening systems The present invention relates to an Internet of Things (IoT)-enabled brine salinity monitoring system for smart salt harvesting in salt evaporation ponds. The system comprises a corrosion-resistant conductivity sensor configured to continuously measure brine salinity, along with temperature and water-level sensors for monitoring environmental parameters influencing evaporation and crystallization. An ESP32-based control unit acquires and processes the sensor data, compares measured values with predefined threshold limits, and determines optimum conditions for salt harvesting. An IoT communication module employing GSM and/or Wi-Fi transmits real-time monitoring data to a cloud platform, enabling remote access through a mobile application or web dashboard: The system generates instant notifications through SMS, GSM, Wi-Fi, or mobile applications when monitored parameters exceed predetermined limits. A solar-powered rechargeable battery provides low-power operation. The system further enables future integration of artificial intelligence-based prediction, automated water control, and advanced analytics, thereby improving monitoring accuracy, harvesting efficiency, operational sustainability, and decision-making in salt production processes.
