Modeling of water temperature in evaporation pot with 7 Ds18b20 sensors based on Atmega328 microcontroller

Abstract

Making a model of the air temperature in the pan to see the difference with 7 DS18B20 sensors based on the Atmega328 microcontroller aimed at the temperature between air temperature, air surface temperature, and airbase temperature. Indonesia has a very wide ocean area and the natural resources in its sea area are not maximized. The use of a pan is a prototype of the breadth and depth of the ocean. making this model can also predict the location of fish and the growth of coral reefs. This temperature modeling is carried out in the evaporation pan with 7 sensors with 2 sensors in the air, 2 sensors on the surface of the water, and 3 sensors at the bottom of the evaporation pan to look for changes in temperature on the sensor and compare it with a mercury thermometer and then see the level of stability of the data. from the obtained graph. The DS18B20 sensor, which has an accuracy of ±0.5?, will be more stable than the mercury thermometer owned by the Geofusuka Station Class II Sanglah Denpasar.
