Ardudrop_logo

ArduDrop is a low cost device, based on Arduino platform, for environmental data acquirement in order to apply the FAO Penman-Monteith methodology (Allen et al., 1998) to calculate the evapotranspiration for crops, what will result in an adequate water management.

Present version:

  • Hardware version 1.3 (20110901)

  • Firmware version: 0.7a (20110901)

Updates:

  • September 1st, 2011. Update to version 1.3 by adding of 2 optional sensors: an evaporation tank, and a rain gauge.

  • October 30th, 2010. Update to version 1.2 by adding of 2 shields (datalogger and screw/power), and wind speed sensor.

  • March 1st, 2010: Updated to version 1.1 by the inclusion of ground temperature sensors in order to derive geothermal flux.

  • December 28th, 2009: version 1.0

Under construction:

  • May, 2012: Wireless Bluetooth connection system.

  • November, 2011: New power supply based on LIPO battery, a solar cell and a battery charger (LIPO-Rider, Seeedstudio).

  • August, 2011: Software develop for ArduDrop-PC communications and data download.

  • December, 2010: multiples (3) combined soil temperature and moisture sensors for substitute the present soil moisture and soil thermal flux sensors.

  • May, 2011: Mini-evaporation tank with automatic measurement device to derive ET0, and compare the results with ArduDrop measured values. It will be an optional sensor for the ArduDrop 1.3 device.

  • May, 2011: 24LS256 EEPROM memory to save data, configuration parameters and error control for ArduDrop device.

  • May, 2011: Improvements on power issues for the ArduDrop device. Probably we will use a commercial solution (e.g., lipo-rider solar charger and li-po batteries).
