A STUDY ON TEMPERATURE AND HUMIDITY MONITORING SYSTEM BASED ON WIRELESS SENSOR NETWORKS (LEACH PROTOCOL)

Abstract

Wireless Sensor Network (WSN) use of in this study of temperature and humidity monitoring system calculate network wirelessly that yourself from a bunch node which is spread on an area certain.. In order to solve this problem, combined with the wireless sensor network technology, based on the digiXBee, according to the architectural characteristics and environmental parameters of ancient buildings, we designed and implemented a humidity monitoring system suitable for environment analysis. The hardware part designs the sensor nodes, and the software part designs the system's routing strategy. The sensor node in the system sends its own temperature, and humidity to the coordinator node through the wireless module. The coordinator node sends the collected data to the monitoring host through the serial port and displays it on the monitoring host software. The monitoring host can send these data to the mobile phone of the Android system through the communication network so that the monitoring personnel can understand the situation at any time. LEACH Algorithm is implement on a system consisting from 9 sensor nodes and 1 sink node. Each sensor node carry out temperature monitoring and humidity surrounding. Testing the system is done with men count the number of data snippets per Cluster Head selection process in each LEACH cycle. Charts based on test results, implementation algorithm LEACH got it increase performance living network. Algorithm LEACH with 70 times snippet data is optimal state which produce time holdup jar light of 7,386 seconds, while with the number trailer data same when using a Non-LEACH algorithm network life time can only reach 6525 seconds.
