GSM (Global System for Mobile Communication) and CDMA (Code Division Multiple Access) are two dominant technologies for mobile communication. These two technologies differ in the way calls and data travel over the mobile phone networks take place. On comparing both the technologies GSM has some limitation when the call quality is concerned but still has…
How to interface GSM Module with PIC18F4550 Microcontroller- (Part 17/25)
The Global System for Mobile (GSM) communication is the Second Generation of mobile technology. Although the world is moving towards Third and [[wysiwyg_imageupload::]]Fourth generation but GSM has been the most successful and widespread technology in the communication sector. GSM technology paved a new way for mobile communication.This project explains the interfacing of a GSM Module with a PIC microcontroller. It also covers a way to dial a particular GSM mobile number as well as send a message to it using AT Commands with the help of PIC18F4550.As explained earlier (refer GSM interfacing with 8051), a line converter MAX232 is employed to convert the RS232 logic data of GSM Module to TTL logic so that it can be processed by the microcontroller. In this project, instead of RS232 logic data, TTL logic output has been taken and thus PIC18F4550 has been directly connected with GSM Modem without any line converter in between. The following diagram shows the TTL input and output of GSM modem used.
How to interface GSM Module with 8051 microcontroller (AT89C51) using PC- (Part 38/45)
GSM is widely used mobile communication architecture used in most of the countries. This project demonstrates the interfacing of [[wysiwyg_imageupload::]]microcontroller AT89C51 with HyperTerminal and GSM module. It aims to familiarize with the syntax of AT Commands and their Information Response and Result Codes. The ASCII values of characters in the Information Response, Result Codes and their syntax can be monitored by an LED array. For the basic concepts, working and operation of AT commands and GSM module refer GSM/GPRS Module. The project explains interfacing of the AT89C51 microcontroller with the GSM module and the HyperTerminal. HyperTerminal is a Windows application. TheAT commands are sent by the HyperTerminal to the GSM module. The Information Response and/or Result Codes are received at the microcontroller and retransmitted to the HyperTerminal by the controller. Read on to understand how does this circuit work and how its microcontroller can be programmed.
How to interface GSM Module with 8051 microcontroller (AT89C51) using PC and LCD- (Part 39/45)
This project is an extension of interfacing microcontroller with hyperterminal and GSM module. The previous project explained a way to interface a GSM [[wysiwyg_imageupload::]]module with 8051 microcontroller where the information response and result codes received by the controller were sent back to computer to display them at HyperTerminal. In this project, the same output is displayed on a 16×2 LCD interface. This project is first step towards making and independent system using the GSM module and a microcontroller. Here the HyperTerminal (computer) has been replaced with LCD at the output end. In the next project (MC076), the AT Commands will be transmitted to the GSM module by the microcontroller itself thus avoiding the need of using HyperTerminal entirely. This project adds a feature to display the information response and result codes on a 16×2 LCD in response to the AT commands sent through the HyperTerminal of computer. The characters typed at HyperTerminal get transmitted serially through the transmit pin (Tx) of RS232 interface.
GSM/GPRS Module : All You Need To Know
GSM/GPRS module is used to establish communication between a computer and a GSM-GPRS system. Global System for Mobile communication (GSM) is an architecture used for mobile communication in most of the countries. Global Packet Radio Service (GPRS) is an extension of GSM that enables higher data transmission rate. GSM/GPRS module consists of a GSM/GPRS modem assembled together with power supply circuit and communication interfaces (like RS-232, USB, etc) for computer.GSM/GPRS MODEM is a class of wireless MODEM devices which requires a SIM (Subscriber Identity Module) card just like mobile phones to activate communication with the network and an IMEI (International Mobile Equipment Identity) number for their identification.
Arduino Based Wireless Notice Board – Send Notice Using Your Cell Phone
You can see the notice boards being used specially at offices and public places to display important news and notices. To make the notice boards easy to use and more technical advance, I have used this prototype of wireless notice board where we can display the message by simply sending the message through your cell phone. These display systems are very accurate and easy to control and cheaply available and the most important thing is that they can be operated on low Voltage (Up to 12 Voltage).A GSM module is used here for the wireless notice board to send the information or message to display. The main aim of this project is to save time and provide information urgently on display for the customers.
Wireless Electricity Meter Reading using Arduino and GSM
In present time Electricity is the necessary thing in the world for human life. Today every home, offices, companies, industries have electricity connection.So here this project is building only for interfacing electricity energy meter with microcontrollers. Here, Arduino is used for interfacing. And the main aim of this project is to know, how much unit is obtained and the total amount of rupees has to be paid. This will help both the inspector and the owner of the place where the meter is placed, we can simply view the unit and the total money that we have to paid and also send to our cell phone using GSM module.
Mobile Phone Simulator using GSM module
This is an interesting application which controls the GSM modem using software designed and developed in C# on .Net framework. There is no need of microcontroller in between. The GSM modem is connected to the PC using a cross connection serial cable. This is a sort of mini simulator for mobile phones. Using this…
GSM-based Industrial Automation
Automation or industrial automation or numerical control is the use of control systems such as computers to control industrial machinery and processes, reducing [[wysiwyg_imageupload::]]the need for human intervention. In the scope of industrialization, automation is a step beyond mechanization. Whereas mechanization provided human operators with machinery to assist them with the physical requirements of work, automation greatly reduces the need for human sensory and mental requirements as well. Processes and systems can also be automated. Automation plays an increasingly important role in the global economy and in daily experience. Engineers strive to combine automated devices with mathematical and organizational tools to create complex systems for a rapidly expanding range of applications and human activities. In some industries proper maintenance of the controlling system or industrial devices is crucial to deliver an uninterrupted output. So to reduce the maintenance costs and to optimize critical monitoring system GSM Based Industrial Automation Technology is used.
