ALLGEMEINE BESCHREIBUNG

The objective of this module is to show some of the techniques used to measure light or illumination intensity.

The module is equipped with a lamp whose light intensity can be controlled by the variation of the voltage supplied.

This module has:

  • Lamp.
  • Photodiode.
  • Phototransistor.
  • Light Dependent Resistance (LDR).
  • Photovoltaic Cell.
  • Infrared emitter-receiver.

All the connections from the different transducers and the lamp are made using a group of 2 mm. terminals placed on the front panel of the test module with drawings describing their functions.
