A Zigbee-Based Animal Health Monitoring System An animal health monitoring system for monitoring the physiological parameters, such as rumination, body temperature, and heart rate with surrounding temperature and humidity, has been developed. The developed system can also analyze the stress level corresponding to thermal humidity index. The IEEE802.15.4 and IEEE1451.2 standards-based sensor module has been developed successfully. TheZigbee device and PIC18F4550 microcontroller are used in the implementation of sensor module. The graphical user interface (GUI) is implemented in LabVIEW 9 according to the IEEE1451.1 standard. The real-time monitoring of physiological and behavioral parameters can be present on the GUI PC. The device is very helpful for inexpensive health care of livestock. A prototype model is developed and tested with high accuracy results.
