MUMBAI, India, Jan. 23 -- Intellectual Property India has published a patent application (202521124640 A) filed by Rakhi Jaykumar Bharadwaj; Sakshi Rajeshwar Dhamdhere; Dev Vinod Lahrani; Sarthak Nagesh Dhang; and Amod Mahendra Dhede, Pune, Maharashtra, on Dec. 10, 2025, for 'smart hvac condition monitoring and fault detection system.'
Inventor(s) include Rakhi Jaykumar Bharadwaj; Sakshi Rajeshwar Dhamdhere; Dev Vinod Lahrani; Sarthak Nagesh Dhang; and Amod Mahendra Dhede.
The application for the patent was published on Jan. 23, under issue no. 04/2026.
According to the abstract released by the Intellectual Property India: "This invention presents a compact, ESP32-based condition-monitoring device for HVAC assets that fuses vibration, electrical current, and ambient temperature/humidity sensing to detect early signs of mechanical and electrical faults in real time. The system acquires signals from an SW-420 vibration module, an ACS712 current sensor, and a DHT-class temperature/humidity sensor, processes them on-device with offset calibration and averaging, and exposes clear local feedback via a character LCD and status LEDs for immediate technician action without cloud dependency. By comparing live measurements against learned baselines and threshold bands, the device flags anomalies indicative of imbalance, bearing wear, misalignment, overload, or airflow issues, enabling predictive maintenance that reduces unplanned downtime and extends equipment life. Designed for low cost and scalability, the architecture operates fully at the edge while remaining ready for optional IoT telemetry and dashboards, supporting broader building maintenance programs focused on reliability and energy efficiency."
