General Description
This unit allows different practices related to the measurement of light intensity to be carried out. Photodiodes are semiconductor light sensors that generate a current or voltage when the P-N junction in the semiconductor is illuminated with light.
With Applications of Light Unit, "M44", designed by EDIBON, different practices related to the measurement of light intensity are carried out.
The unit has five different types of light sensors: photodiode, phototransistor, photovoltaic cell, photosensitive resistor and infrared sensor.
By studying the different sensors, it is possible to compare their mode of operation and determine their advantages and disadvantages.
