To evaluate the animal welfare, many ranchers would like to know the pressure on the animals due to the holsters and ropes. In this paper, a wireless real-time pressure monitoring system was designed based on wireless sensor network. The system consists of several pressure sensor nodes and a sink to coordinate the whole network, collect data from pressure sensor nodes and send the data to PC. An ultra-thin pressure sensor was integrated in the smart moteplatform to form the pressure sensor node. TinyOS, an open-source operating system and nesC language, an extension to C were applied for programming. In the lab test, the result of sensor calibration shows it has a good linearity and the packet delivery rate test verify that the system could operate stably and reliably in a better acceptable link quality. For better presenting to users, an information monitoring interface was used based on MATLAB as a simple demonstration of the whole system.
