Modifikasi Penakar Hujan Otomatis Tipe Tipping Bucket dengan Hall Effect Sensor ATS276

Abstract

ABSTRACT Rain is one of the meteorological parameters were observed in the BMKG. Current measurement is done by an automated tool, although it is still commonly found measurements made with conventional tools in the field. Existing automatic tools are still expensive then needed rain gauges are reliable at an economical price (techno economic). It works using a magnetic sensor ATS276. The principle is the same as the other switches, each tip is happening, magnet meets the switch will be on. When on, the switch will provide input to the signal processing circuit, the input is processed. Once processed, the data processing results displayed on a monitor and stored. This experiment was modifying a rainfall gauge to replace existing magnetic sensor that is more easy to use. Magnetic sensors as graduated rainfall using a tipping bucket type tool with a resolution of 0.5 mm. This tool will display the measurement results and measurement results in a computer store. The measurement results were achieved with these tools produce data with about 98% accuracy rate.
