Automatic Water Temperature Control System In Hydroponic Plants With Peltier Tec1 12706 And Temperature Sensors DS18B20

Abstract

Hydroponic planting techniques are generally carried out by flowing nutritious water into pipes that have been given holes for plants. Overheated water temperatures in hydroponic plants will cause plants to wither and grow not maximally. So it is necessary that the temperature of the water that is too hot can be reduced to a good extent for plants. This research aims to create a water-control system in hydroponic plants to use peltier Tec1 12706 to lower water and DS18B20 sensors ro measure water temperature. So that plant growth is maintened well. From the test results, it is known that the temperature of solar hot water from 38.10˚C drops to 30.31˚C with every 10 minutes of recording data and within a period of approximately 4 hours the water temperature can drop to 7.79˚C. although it has not reached the normal temperature of hydroponic water, which is 28˚, Peltier is stable in decreasing water temperature without any fluctuations in temperature. So this peltier is very effective in reducing water temperature.
