Laos is an agricultural based country. As agriculture is the main source of\nfood for any country, it is important to have a proper irrigation system. This\npaper shows a design of automatic irrigation system based on android application\nusing Raspberry Pi microcontroller, soil moisture and temperature\nsensor to help a famer to control and monitor a farm. This work facilitates the\nfarm irrigation by switching the pump motor ON/OFF through android cell\nphone. This automatic irrigation system has a low cost and can be affordable\nby many Lao farmers. The study shows that the system is useful to provide\noptimal amount of water for increase the productivity of crop.
