Design of a Certain Airplane’s Hydromatic Systems Pressure Measurement Device with TLS
A Certain Airplane’s Hydraumatic Systems Fault Diagnosis Device was designed, but there were some nonlinear factor within the sensor’s input-output, and the magnify circuits; there were many random errors in the used components. So the obvious relation of the input-output could not be found. A least square method was adopted in nonlinear fitting, so the hardware and software of this Fault Diagnosis Device were simplified.
The main purpose of this study is to present a complete irrigation solution for the farmer based on wireless sensor network. The challenge is to create an automated irrigation system which can reduce in the same time the water's waste and is cost effective. Different parameters are important to measure in order to calculate the efficient quantity of water needed by plants. In this study, the proposed solution is the use of low-cost sensor nodes having reduced power consumption able to realise necessary requirements. The system is composed of different types of nodes. Each node consists of a TelosB mote and adequate sensors or actuators. Soil nodes are used to detect the level of moisture and temperature in soil. Weather nodes monitor the climatic changes. Other nodes are connected to actuators which are able to control the opening of the irrigation valve if necessary.
