Abstract: this study was performed to implement a modern wireless communication system for data collection and communication by using GSM Communication Network as a platform based on SMS. The system depends on EasyPIC5 microcontroller development board as a modern digital communication system together with a smartg100 (GSM) development boards; both development boards are developed and manufactured by mikro Elektronika. This system is used to measure the water level in a field, and implement telemetry over wireless communication network system which Present a solution for irrigation system as an application. In this research a Pressure Sensor (E-Tape Million Pressure sensor) and handmade sensor are used to measure water level value, and calibrating the results. Water level measurement system includes a control center (Base station), a GSM modems, and a telemetry unit (Sub Station), on the other hand the author developed friendly user interface for the wireless telemetry by means of Visual Basic which connect the base station with substations, and create a data base to save a historical data of measured water level. In this Research the author developed an alarm system by using buzzer and flashing leds to warn if there are any errors at any station. Compared to other telemetry systems, in this system the measured data does not sent continuously but it is only sent when the data value is changed, so it provides a minimum size of data reserved in the room service and reduce the cost, on the other hand the other systems send measured data continuously so it reserve the channel all the time and increase the cost. On the other hand in this system we have two way actions, and alarm system which determine the error, where, and how to fix.
