Temperature and Humidity Monitoring System using Wireless Based Xbee on Hydroponic Plants

Abstract

Abstract This research discusses temperature and humidity monitoring systems using wireless Xbee module-based microcontrollers carried out in hydroponic plants. Microcontroller has functions for storing programs in electronic circuits. Xbee has a function for wireless communication devices that work on the 2.4 Ghz frequency with a range of 1500 meters. The technique used in this study used two Xbee modules, which are used as the sending node and receiving node. The sending node is as the controller. It used the Arduino module which is connected to the DHT 11 sensor as input and Xbee as the sender. The receiver node as a data processor consists of Xbee module connected to the Arduino module and LCD to display data. In this research, the results of comparison of DHT11 sensors with a Thermo-Hygro measuring device with an average temperature error of 0.75°C and 3% humidity. The results of testing the four DHT11 sensors outside the room get an average value of 28.94° C with humidity test results in the room 29.14° C and 58.86% with an Xbee range of 70 meters. Wireless design of temperature and humidity monitoring systems based on Xbee communication is successfully implemented in hydroponic plant cultivation.
