Avoid gardening disasters: test performance of drip emitters

Abstract

One of the most common problems that residential gardeners face is the clogging of drip irrigation emitters, but clogged emitter testers are currently unavailable in the consumer marketplace. The device described in this paper uses an Arduino Uno R3, relay, 385 Miniature Micro DC Water Pump, eTape Liquid Level Sensor, an LCD screen, and button to determine if an emitter is functioning properly. Validation results show that the device will be able to successfully rate drip irrigation emitters' flow status and a path forward is described.
