Abstract: This paper describes the design and the construction of a measurement and transmission system of the variables air temperature, relative humidity, soil moisture and precipitation, using APRS. It is described: the conditioning of sensors LM335 and HIH- 3610, the instrumentation used to measure the humidity of the ground and the quantity precipitation; in addition, the operation of the control unit and processing, the module for codification AX.25/APRS and transmission AFSK/FM using the format of telemetry and position of the Automatic Position Reporting System (APRS). The module constructed allows the surveillance, local and remote of the agrometeorologic characteristics in situ, necessary to make decisions and to do actions focused to: to protect the cultivated zone of the abrupt changes of the climate, to experience new processes of farming development and to obtain a representative data base of microclimates of the monitored agrarian zone.

Keywords: Agrometeorology, APRS, Geolocation, Sensors, telemetry.
