In this post I will be showing you a demonstration on sending and receiving SMS using VB.NET and AT commands. The previews post talks about how you can make your own SMS gateway software with the use of AT commands and VB.NET. The use of your own mobile phone as a GSM modem you can make an application that would send SMS and eliminate the cost of buying an SMS gateway application for your small project.
I uploaded a video demo of the project mentioned in the previews post. This is a VB.NET SMS window form application. Enjoy the video! Cheers!
There are a lot more techniques to improve this project. I am thinking about an application that would open an automated door lock with just a single SMS. Something like "COMAND = OPEN PASSWORD = z5a2q6a". We can also shut down our computer with an SMS command and a lot more. Feel free to explore and integrate AT commands in other languages such as C#, JAVA, PHP and many more.
sir, can you send the codes/application??
ReplyDeleteTry creating the project on your own. We can try to discuss here if you cant achieve the desired result.
ReplyDeletemy thesis is about student attendance monitoring system my thesis scenario is "the student enters the campus she or he must scan his or her id using barcode scanner then his/her information show on the screen and the sms will send to his/her parent that she or he arrive at school with time and date?"
ReplyDeleteAn SMS always have a date and time. I dont see any problem about that.
ReplyDeletethe actual date and time when the student scans their id. . .the date and time will be the body of my message for example good evening your son "name" arrived at school at 10:02 pm 7/31/2011 . .
ReplyDeleteIt depends on your design or on the barcode algorithm that you are using. You can use a button event as well. For example the button(Validate) will trigger an event that would validate the Student ID from the barcode with that of the database. If the result of the validation is true, then simply call the function to sent SMS. Provide the string for the SMS. Example:
ReplyDeletestrSMS = "NAME arrive at school at" & Date.Now().toString()
Where strSMS is the body of your message.
