A Low-cost Automatic Water Sampler Equipment

This work aims at presenting an automatic low cost water sampler prototype. Data provided by this equipment can be used in water resources management and control. Prototype has an electronic system which controls a peristaltic pump functioning, five solenoid valves and an ultrasonic sensor that provides water level measurement data. An interface with the user provided by a board and LCD display allows sampling parameters input and a report output when sampling is over. Hydraulic module uses a peristaltic 12V pump connected to five solenoid valves, which distribute sample and clean PVC tubes once each sampling is produced. Storage module contains four plastic bottles, 1.95 . Prototype structure is made of acrylic, 0.72 m height and 0.38 m diameter. Experimental laboratory runs have showed a successful performance.
