Sensor Deployment

Laboratory Test - Cantilever Beam Experiment

Test Time and Location

Date: July 29, 2025 4:00 PM - 5:00 PM Location: ZS1107

Objectives

  • Learn to use a wireless sensor network for data acquisition and transmission
  • Calibrate the sensors

Equipment

  • ArduinoNode
  • Wired sensors
  • Cantilever beam structure

Test Procedure

  • After placing the sensors into their enclosures, fix and attach them securely to the cantilever beam. Ensure the wired sensor and the ArduinoNode sensor are placed closely and firmly together.
  • Simultaneously collect data from both the wired sensor and the ArduinoNode sensor.
  • Retrieve sensor data from the SD card module.
  • Plot the time-history curves and frequency spectra of the sensor data.
  • Calibrate the scaling factors of the three axes of the sensor.
