Sensor Coursework - Calibrating a Potentiometer sensor. Introduction Sensor: A device capable of detecting and responding to physical stimuli such as movement, light or heat. All sensors have an input, which can be any physical variable, Common examples include, temperature, position, light intensity, and sound. This input is then converted into a readable output, normally an electrical signal. Sensors are extensively used in the modern world, and are important components in many household electrical appliances such as ovens, computers, and televisions. The purpose of this experiment is to calibrate a sensor, which involves establishing and marking units on a measuring device. In electronic sensors, the calibration is achieved by the production of a graph with input plotted against output. From the resultant curve, expected output can by interpolated for a given input, and vice versa. Aim The aim of this investigation was to calibrate, and investigate the properties, of a sensor that finds the weight of...
