The objective of this dissertation is show the design of a structural integrity monitoring system, employing sensor network.
The project of sensor node allows many kind of sensors, such as electrical strain
gage, accelerometer, temperature sensor, humidit sensor, also the sensor node is capable of communicating via wireless and wired technology. In contrast to conventional systems that are centralized and employ long cables, the use of a sensor network is a decentralized approach, allowing the sensors are closer to the conditioning circuit, this brings certain bene_ts, such as reducing the length of the sensor cables decreasing the uptake of electromagnetic noise and decrease the impedance of the cable, improving the response signals generated by sensors.
They will be presented details of the circuit and the sensor node communication.
