Animal Welfare using Wireless Sensors Technology


A major advantage of wireless transmission is a significant reduction and simplification in wiring and harness. Wireless Sensor Networks (WSNs) is one of these wireless technologies which are used nowadays. They can operate in a wide range of environments and provide advantages in cost, size, power, flexibility and distributed intelligence, compared to wired ones. It is an infrastructure comprised of sensing, computing and communication elements that gives us the ability to monitor and react to events in a certain environment. WSNs have four components: an assembly of distributed sensors, an interconnecting wireless network, a central point of information gathering, and a set of computing resources at the central point.

In animal welfare sector, it is always desirable to implement a health monitoring program to monitor the condition of animal as well as to prevent the outbreaks of animal diseases. Various researchers have used wireless networks with a mounted sensory device to track individual animal activity and to track the health condition. In this lecture, three types of animal welfare WSN technology systems will be explained and there are poultry farms systems, cattle monitoring systems and smart farm systems

In the poultry farms, multiple sensing areas are needed to monitor the local climate variables in different zones of the large poultry farm to make the automation and control system work effectively. In modern poultry farm monitoring system, temperature and humidity values not only are monitored but also it is possible to automate the monitoring of these environmental parameters instead of using the conventional monitoring methods and controlling the parameters automatically.

In the cattle monitoring system, the animal is free to move around and wireless methods are considered the only feasible solution to establish and maintain communications between a center base station and sensor attached on cattle. Monitoring climate related variables within an animal house can help maintain good animal health.

Smart farmers could monitor cattle in the paddock from the comfort of their own home or know where there are green pastures for their cattle to eat. It could mean locating machinery and equipment or joining a teleconference with local farmers to discuss crop prices. Farmers on a smart farm could access remote expertise and assistance via portable video services when needed for diagnosing or trouble shooting issues such as the breakdown of an important piece of machinery.
