This paper presents a biosensor-based cattle health monitoring system capable of collecting bio-signals of farm animals in an effective way. For the presented monitoring system. We design an integrated monitoring device consisting of a sensing module to measure bio-signals of cattle such as the heartbeat, the breath rate and the momentum, as well as a Zigbee module designed to transmit the biometric data based on Wireless Sensor Network (WSN).

Since the infectious diseases may cause fatal damages in the communities and countries, it is greatly important to prevent livestock diseases, such as foot-and-mouse disease, from spreading through monitoring and forecasting efforts. In order for Korea’s cattle farms with high density of livestock to effectively control the infectious diseases, it is urgently required to introduce a monitoring and forecasting system as well as a new management system based on the bottom-up approach, in which a case of an individual farm can be adopted to other farms in the region. Previous cattle health monitoring systems are restricted to monitor changes in the environmental conditions of livestock barns such as temperature and humidity, or collect data of cattle activities by means of a pedometer or thermal images, making it difficult to produce precise predictive information regarding the occurrence of livestock diseases. Meanwhile, in the livestock industry, biosensors have been increasingly utilized not only to efficiently produce dairy goods but also monitor the livestock’s health conditions. In this paper, we design an effective livestock monitoring system (LMS) using biosensors for cattle health monitoring systems. The monitoring system intends to Advanced Science and Technology Letters Vol.117 (BSBT 2015), pp.180-185 http://dx.doi.org/10.14257/astl.2015.117.42 ISSN: 2287-1233 ASTL Copyright © 2015 SERSC
