SIM800_GSM_GPRS is an Arduino library for SIM800C/SIM800L modules. It enables sending/receiving SMS, making/answering calls, and performing HTTP GET/POST via GPRS. Compatible with Arduino, ESP32, and STM32, it offers simple APIs, network detection, IoT, IMEI retrieval, and event-driven SMS/call handling.

This project uses TTGO T-Call module to deal with calls and messages, monitor its surroundings and alert user via call or message if any environmental changes detected by ultrasound sensor.

Arduino-based GPS and GSM accident detection system using an FSR sensor to detect impacts and automatically send real-time SMS alerts with live location coordinates.

ESP32 Setup Portal with WiFi, GSM, and OTA features

This Arduino project is an emergency alert system using GPS and GSM modules. When a button is pressed, it captures the current location and sends an SMS with a Google Maps link to a predefined phone number. A buzzer activates to confirm the message was sent. The system is ideal for personal safety or emergency tracking applications.
