Redesign and improvement the effectiveness of automatic plant waterier

Abstract

This project is to redesign an automatic plant waterer for domestic purpose. In order to develop an effective drip irrigation system to the automatic plant waterer, the special design of emitter and electronic sensing circuit were included. The labyrinth path in an emitter was used to regulate water discharge at a constant rate. The research of relationship between emitter’s hydraulic performance and its labyrinth structure of path was carried out. Three different dimensions of trapezoidal shaped labyrinth path emitters will be tested in term of discharge flow rate and anti-clogging property. The electronic temperature sensing circuit will be built for the automatic plant waterer as an assist device to avoid over watering issue. The effectiveness of the circuit will be investigated by experiments since it is a new method to improve irrigation quality of an automatic plant waterer.
