Gas Leakage Detector using Arduino and GSM Module with SMS Alert and Sound Alarm

The code for interfacing PIR Sensor and GSM SIM900A Module with Arduino UNO. Created as an IoT mini-project for Semester 5, as mentioned in the University's curriculum.

A wireless notice board built using Arduino UNO, GSM module and LCD display that conveys messages directly from user's phones onto the screen.

An Arduino-based home alarm with RFID, GSM and Bluetooth capabilities. More features are remote motion sensors and a database that stores all user info if the power should go off.

Smart Question Box built with Arduino to prevent question leakage in public exams.

Generate automatic voice calls with a Raspberry pi and SIM900 GSM module

Modified header file to effortlessly communicate with SIM modules

The unit receives a textmessage to the GSM-module, if the message is correct, it sends it to a RPi using NRF24L01 2,4GHZ modules. The pythonscript translates message and takes picture with picamera and sends it to a Gmailadress!

Bus (vehicle) tracking system using GPS neo 6m, GSM SIM 900a, arduino and google maps. The system was made for the purposes of Jashore University of Science & Technology bus tracking

Accident Detection System using GSM, GPS and Accelerometer modules.

Contains home security/automation modules for motion detection and temperature alert (used Raspberry Pi Zero). Output trigger and module's setting could be configured from a computer software. Raspberry Pi Zero communicates through the TCP connection. The package keeps the log of motion detection and the temperature. It also has SMS alert features.

Simple library for SIM800 GSM module

The scenario that the device apply during the leakage of the gas briefly is: when the gas detected cross the threshold adjusted by the developer it will inform the user that there is a gas leakage in the form of a SMS massage just to keep the user up with the situation. However, the device will immediately take the action of closing the main val…
