PENAKAR CURAH HUJAN AUTOMATIS MENGGUNAKAN MIKROKONTROLER ATMEGA 32
ABSTRACT: Indonesia is one
kind of country which has wet tropical climate (humid tropic). The character
has always high volume of rains. The average for each year in Indonesia isn’t
in the same portion. But there still much more, an average 2000–3000 mm/year.
And also between one and the other places have different rain rates. Areas
which have rain rate less than 1000 mm, coverage of 0,6% from Indonesian
territory, There are South east of Nusa, and 2 areas in Sulawesi (Palu valley
and Luwuk). And some areas which have rain rates between 1000 – 2000 mm in a
year there are some part of South east of Nusa, a little part of Merauke, Aru
Archipelago and Tanibar. The areas which have rain rates between 2000 – 3000 mm
per year, coverage East Sumatra, South Kalimantan, East part of West Java and
Central Java, and some part of Irian Jaya, maluku Archipelago and some of
Sulawesi. The area which has the most portion of rain 3000 mm per year is high
land of West Sumatra, Central Kalimantan, and central plateau of Papua, more
areas in Java, Bali, Lombok, and Sumba. Since this conditions, needed to
improve a tools to detect total of rain rate prototype, so rain rate data in
one place could be known quickly. This is so meanly to give advantage, for
example to anticipate or warn from flood disaster or even landslide. In this
research designed hardware to detect rain rate automatically using tipping
bucket rain rate sensor. This sensor employed based on signal pulse caused of
tipping moving from the rain which called click. Once click produce one pulse
feed up to microcontroller to be recorded. Once click shows the number of flow
rains 5,5 mm. Total flow rains recorded and accumulated from 06.00 until 17.00
and from 17.00 until 06.00. This result saved in its memory to an exact time
suitable with memory capacity which still available in microcontroller.
