Wireless remote controlled for multi-station irrigation

Abstract

This paper presents the development of a wireless remote-controlled system with dual-tone multi-frequency (DTMF) signaling transmitter using android application system for multi-station irrigation and fertilizer dispersion. Fertigation are combination of two words which are fertilizer and irrigation. To be more precise, fertigation is the process of applying fertilizer through an automatic irrigation system. Plants need enough both of nutrients and water supply in order to grow up and produce a high market value crop. Inaccurate amounts of water and fertilizer can lead to unhealthy plants growth and the worst is, the plants will be dead. Although there are the timer-based fertigation systems, the system cannot control the exact amount of fertilizer and water needed by the plants as they operate by supplying same amount of water and fertilizer in a specific time set without considering the weather and soil condition. The android application system allows users to send commands from their smart phones to control various type of appliances such as lighting, watering, timer or even fertilizer. The system is equipped with Arduino Uno and relay drivers circuit for controlling the system appliances. The system is suitable for long range control applications which mean can be control by any device that using dual-tone multi-frequency signaling transmitter from anywhere in the world.
