The Design of Wireless and Distributed Temperature Monitoring System for “Tungku Gama” Grain Dryer

Abstract

In order to overcome Bantul „s farmers which have severely problem when harvesting paddie at rainy session, it has been built a grain dryer. This drying machine utilize “Tungku Gama”, which is a furnace using husk as fuel. A temperature monitoring system is introduced. This equipment built as a distributed sensor network, based on a ATMEGA micro-controller and X-bee communication module. It uses A-component and B-component as a temperature and a humidity sensor respectively. The system has ability to monitor multiple locations simultaneously, where each location consists of four cabinet dryer each having eight shelves. Each location is equipped with a data-logger or data-concentrator. Due to the distributed locations of the grain dryer, a monitoring center is made and is connected with each data-logger by a wireless communication.
