Why Short Messaging Service

A way to extend communication between XO and mobile phone devices that does not have GPRS capability i.e. the only way possible to communicate with them is through text messages/voice calls.

It can be used as an information medium and for communication with others (e.g. Parents).

How does it work?

The main idea is to interface a modem/GSM AT compliant mobile phone with the School server. It hosts a SMS Gateway which can be accessed by XO through web browser.

SMS Server Tools are used for communicating with the phone and PlaySMS is used for hosting SMS Gateway.


You would need a temperature sensor like this one LM35. A link is here- http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail?name=LM35DZ-ND
Taken from the data sheet of the temperature sensor, Vs is where we would supply the "+ve" (positive supply voltage), gnd is where would connect "-ve" (ground) and Vout is the sensor output which we will connect to "Vinput"
So we connect the "Gnd" to the righten-most terminal of the sensor

My task will be to handle different queries that can arise in this situation.

1. Handle the queries received from the parents about their child location. 2. Handle information sent by teachers and route them to student's laptops: Information can be regarding all happenings (e.g. results notification, attendance record, assessment deadlines, feedback from tutors and other urgent administrative details) 3. Students can send SMS queries to teachers and to other concerned communities.
