ArduDrop device has been developed to study soil moisture and its relation to environmental parameters. In this work, focusing on the calculation of evapotranspiration, a water balance parameters, we justify that two new sensors should be included into the device: irradiance and wind speed, what we describe here. On the other hand, the first version of this device has been enhanced electronically. The description of these improvements is also the aim of this work. But these changes also aim to design two shields for Arduino Duemilanove containing the device microcontroller, in order to consolidate the various devices and sensors attached to it, and improve the power supply of them. These shields are (1) a shield for data storage, with a Real Time Clock, which also allows alarms configuration, and an SD memory card; and (2) a shield for sensors connection and power supply, including screw terminals which connect different peripheral sensors on the device. Finally, we show the new code of the program (Firmware) designed to acquire data from new sensors and electronic enhancements take to reduce energy consumption.
