Project Title: Strain gauge measurement system
Course Suitability: BSc. (Electronics)

Project Description 

The principal of operation of a foil strain gauge is that its resistance changes with applied strain. The resistance change can be detected by including the gauge in a resistive bridge circuit such as a Wheatstone bridge. In this project the gauge will be used to measure the strain experienced by a bent metal rod. The electrical signal from the gauge will be acquired by a microcontroller, which will process the sensor data to determine the strain and display it on an LCD module.

Tasks include

Understanding the operation of foil strain gauges.

Design of a suitable resistive bridge.

Signal acquisition and processing using the microcontroller.

Real-time display of the strain on an LCD module.

Useful link to the microcontroller evaluation kit.
