The precision irrigation consists in the water application atlocal, momentand quantity required by the crop, and forthat turnspossible it will be necesserymethods that provide the decision parameter making the act of irrigating less empirical and more technical. The use of capacitive soil moisture sensors allows the monitoring of soil moisture levels and, consequently, an automation irrigation. Therefore, an automatic irrigation system,demads communication betweenthe controller and the starting and sensing points. When there are large distances between them, appears a necessity to use Wireless Sensor Network (WSN) to reduce costs and connect these points through radio frequency communication. According with the exposed, the present work was goal developed na WSN providing a communication between the modules that control the components of the irrigation system. The work was desenvolved in the Laboratory of Electronics and Agricultural Mechanics (LEMA) of the Federal University of Ceará (UFC). Initially modules were developed to: collect and transmit capacitive sensor data (sensor module); control of valve control latch and set irrigation sectors (valve tristle module); control the motor-pumpassociatedwithfrequencyinverter (pump house module); accomplishthe interface between field modules andmanagement software (control module). After than, the development of control software based on the Android operating system for mobile devices, having as a development platform the online paltform MIT APP Inventor. It was observed in the results thatthe developed hardware it meets the communication needs between the control module and the set modules and the sensing modules. The sensor module precise performed thedata acquisition coming fromthe capacitive sensors of soilmoisture,as well the valve tristle module it was able to open and closeof the valve control latch in a satisfactory manner. Themobile applie,"IrrigBlue",developed for Android devices was able to processthe dataspackets received from the WSN, processing and return to the user the status ofirrigation system, besides generating data packets withset comandingsof the irrigation systemthrough the "IrrigBlue" hardware.
