Abstract
Wearable and Compact Wireless Sensor Nodes for Measuring the Temperature of the Base of a Calf's Tail
Highlights
To achieve a safer and more secure society, wireless sensor network technology has been a promising approach for a variety of applications, such as structural health monitoring, human body monitoring, and animal health monitoring.[1,2,3,4,5,6] Structural health monitoring is for improving the safety and reliability of buildings, bridges, and lifeline systems by detecting damage before it reaches a critical state; the damage is detected by many wireless sensor nodes set on structures.[1,2] Human body monitoring detects sleep disorders, Parkinson’s disease and so on by obtaining information on daily walking and posture using a triaxial sensor, GPS and a magnetic sensor.[3]. These technologies have
Wireless sensor nodes consuming minimal power for chickens,(8) multifunctional sensor nodes for GPS, magnetometers and accelerometers for cattle,(9) and bolus-type sensor nodes have been developed.[10] these sensor nodes for cattle cannot be used
The aim of this study is to develop wearable wireless sensor nodes that can be attached to adult cattle as well as calves using a simple attachment
Summary
To achieve a safer and more secure society, wireless sensor network technology has been a promising approach for a variety of applications, such as structural health monitoring, human body monitoring, and animal health monitoring.[1,2,3,4,5,6] Structural health monitoring is for improving the safety and reliability of buildings, bridges, and lifeline systems by detecting damage before it reaches a critical state; the damage is detected by many wireless sensor nodes set on structures.[1,2] Human body monitoring detects sleep disorders, Parkinson’s disease and so on by obtaining information on daily walking and posture using a triaxial sensor, GPS and a magnetic sensor.[3]. Been introduced into agriculture, including animal health monitoring.[4,5,6] Animal health monitoring systems have enormous potential to prevent the spread of avian influenza and death from illness or injury due to their ability for early detection,(7–10) thereby allowing rapid cures To achieve these applications, wireless sensor nodes consuming minimal power for chickens,(8) multifunctional sensor nodes for GPS, magnetometers and accelerometers for cattle,(9) and bolus-type sensor nodes have been developed.[10] these sensor nodes for cattle cannot be used. The developed sensor nodes, which can measure both temperature and acceleration, are 18×18×7 mm and weigh 6.6 g with batteries Their primary advantage is their compact and small size, allowing easy attachment to any part of the calf. We performed continuous monitoring for 16 d, and compared the daily maximum temperature with the daily maximum rectal temperature
