How to send a GET and POST request with AT commands using the SIM900 GSM/GPRS module and the Arduino UNO. This is useful for retrieving data from the Web and sending data to a web server for Internet ...

Uses Software Serial built-in library to communicate to any type of GSM module. In this case, digital pin 10 and 11 as RX and TX respectively. connect pin 10 to Arduino TX and 11 to Arduino RX. Make ...

You can connect any intrusion detection unit (such as a light fence or a motion sensor) to the input connector J2. Note that an active-low (L) at pin 1 of connector J2 triggers the security system.

In this project, the author is going to construct a system using a Arduino Development board and GSM module. He connects a switch/sensor to the Arduino board along with the GSM module. The user ...

Click to Enlarge. The board can be programmed in the Arduino IDE by selecting Arduino Mega board. SIM808 modem is controlled with AT commands so that might not be the most programmer friendly board ...

An Arduino is equipped with a piezo sensor to detect impact, and a GSM shield takes care of the texting. It’s an interesting concept, similar to requiring police officers to wear body cameras.

This paper introduces the design and prototype of a new home automation system that utilizes GSM technology as the network infrastructure to connect its components. The proposed system is composed of ...

In this GSM based home automation project we are building a home automation system, where one can control the home appliances, using the simple GSM based cell phone, just by sending SMS through his ...

It is built around Arduino Uno board (BOARD1), 16×2 LCD (LCD1), GPS module, GSM module and a potmeter (VR1). Working of the circuit is very simple. To operate the circuit, you need to follow the steps ...
