The project is based on a Gsm/Gps/Gprs. Its main function is to detect a illegal entry and communicate its own geographical position using, on the choice, the cellular phone reference system or the GPS. I use the recent product by SIMCOM - SIM908 which operate on 5 - 12 volt dc supply, which makes it work on wide-range dc power supply... Well i still believe that i can burn a code of 21kb into program memor ...

The project aims at a system allowing user to control home based appliances through Sms along with acknowledgements. Here user need not switch home appliances on and off manually. Our system allows user to operate these devices through sms, also the status weather the device is switched on or not is sent to user via a return sms. This can be used by domestic users and company users to operate as well as che ...

GSM modules are fascinating to use especially when our project requires remote access. These modules could make all actions that our normal mobile phone could do, like making/receiving a call, sending/receiving a SMS, connecting to internet using GPRS etc. You can also connect a normal microphone and speaker to this module and converse on your mobile calls. This will open doors to lot of creative projects i ...

It is installed in cars, and thanks to a detector placed on the child seat, it warns us – via SMS or phone call – if we get away without bringing the child with us. Among the most saddening (and at any rate, infrequent) accidents in the news, there are those of parents that – because of briskness, health problems or lack of attention – get out of the car and “forget” their kids on the child seat, in a hot o ...

So you have got a GSM module lying around like me? Also a GPS-tracker? We think the same! In this instructables, I will try to guide you how to accomplish your goal from a newbie's perspective. As I had no previous electrical engineering knowledge (to be honest, the project doesn't need that much,but nah), and had no clue how to make a device which pumps data real-time to a webserver, I encountered numerous ...

In this project, we are going to develop a PIR sensor and GSM based home security system. This project is developed using 8051 microcontroller. It can be used to detect any intrusion in houses and offices and send the alerts on cell phones. Let us know how to develop this system, step by step. Required Components 8051 GSM Module PIR Sensor Module LM7805 Bread Board LED 1K resistor 10K resistor 1000uf capaci ...

GSM Interfacing with PIC Microcontroller PIC16F877A - Make and Receive Calls GSM modules are fascinating to use especially when our project requires remote access. These modules could make all actions that our normal mobile phone could do, like making/receiving a call, sending/receiving a SMS, connecting to internet using GPRS etc. You can also connect a normal microphone and speaker to this module and conv ...

It’s no the first time that we present a localizer without GPS. We remake the old device with the cheaper SimCom module SIM900. In the previous post we present the GSM section and now we can present the complete localizator. Introduction This system allows for localization without directly using GPS technology; we are able to locate the desired object fairly precisely by using database availability together ...

GSM Modem Interface with PIC 18F4550 Micro controller: Description: In this project we use PIC 18F4550 Micro controller in transmitter section keys are connected to PB0 to PB3. If we press the key PB0 the Pressed Key Value is transmitted to the micro controller section i.e receiver section . In the controller we pre programmed to open the door A. If we press the key PB1 means the particular port is enabled ...

It has been a while since we published electronic engineering projects here due to the busy schedule we had in the past weeks, and this time we’re up with another interesting project. Before going through the details of this one, you may as well check our latest electronics projects for engineering students. GSM based device monitoring and control system are becoming popular these days. Here I am introducin ...
