MUMBAI, India, Oct. 26 -- Intellectual Property India has published a patent application (202611107039 A) filed by Institute Of Technology And Management Gida, Gorakhpur; Dr. Nk Singh; Shalini; Prof. Krishna Kumar; and Shyam Chaurasiya on September 05, 2026, for Esp32-C3 Gps + 4g + Relay Alarm Circuit.
Inventors include Dr. Nk Singh; Shalini; Prof. Krishna Kumar; and Shyam Chaurasiya.
The application for the patent was published on October 23, 2026, under issue no. 43/2026.
Abstract: An embedded alarm and control system integrating GPS positioning, cellular communication, relay switching, and regulated battery power is disclosed. A two-cell lithium-ion battery section supplies electrical energy through regulated power stages providing approximately 5-volt and 3.3-volt rails. An ESP32-C3 controller receives latitude, longitude, time, speed, or satellite information from a NEO GPS module and communicates with an A7670C 4G/GSM module through serial interfaces. The controller executes programmed alarm logic and can transmit alert or location information through SMS, call-related signaling, or packet-data communication. Separate BC547 transistor driver stages operate two 5-volt relays without directly loading controller GPIO outputs. A first relay switches an external load, while a second relay switches a human voice alarm connection. LED indicators provide visual operating status. The integrated architecture coordinates positioning data, remote communication, local load actuation, voice-alarm switching, and low-voltage power management within a microcontroller-controlled electronic alarm platform for event-responsive monitoring and notification operations.
