Building a Sensor to Measure Weight, using a Potential Divider and Wheatstone Bridge. Initial Ideas: Firstly I needed to have an idea of what I would have liked to investigate about sensors, whether it be to evaluate against a ready-made sensor or to build and calibrate a sensor. I decided on building and calibrating a sensor as I feel it would be more creative. Then I brainstormed a couple of ideas to build, for example measuring the speed of water by measuring the time it takes the water to fill a cup, so increasing its weight. Another idea was to build an accurate weighing device that works in two directions, the first the conventional way using gravity and the other using a pulley system to measure the upward pulling force. I chose the second idea as I felt the first idea would be to long an experiment as it involves more stages of...
