The country, being positioned near the equator, have two seasons; wet and dry season. Since then, tropical countries around Asia has been suffering drought brought upon by the El Niño wherein the impact is concentrated on the agricultural sector. In this paper, the use of a Raspberry Pi in controlling an automated irrigation system is explored. Parameters such as temperature, humidity, wind speed, and radiation are taken into account in using an Evapotranspiration (ET) based irrigation system. Evapotranspiration relies on the use of specialized equations, namely: Hargreaves-Samani and Penman-Monteith in determining the amount of water loss through evaporation and transpiration of the plant. The microcontroller determines the minimum amount of water and controls the flow of water in a dripper style configuration through the use of a water pump.}, number={1-14}, journal={Journal of Telecommunication, Electronic and Computer Engineering (JTEC)}, author={Caya, Meo Vincent C. and Ibarra, Joseph Bryan G. and Avendaño, Glenn O. and Felipe, David Joash D.
