General Description
The objective of the Light Test Module, "BS10", 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.
Included elements:
- 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.
Exercises and guided practices
GUIDED PRACTICAL EXERCISES INCLUDED IN THE MANUAL
- Study of the equivalent electrical circuit of a photodiode. Studythe V-I characteristic of a photodiode.
- Study of the normal operation mode of a photodiode. Study the"ON/OFF" operation (light switch) of a phototransistor.
- Measurement of light intensity using a solar cell.
- Study of the properties of light dependent resistors (LDR).
- Study of the operation of IR sensors.
- Study of a real application for controlling the light intensity usingPID control elements.
