TW-LS-C photosensitive sensor photoelectric characteristic tester Introduction: Photosensitive sensor is a sensor that converts light signals into electrical signals, also known as photoelectric sensor. It can be used to detect non electric quantities that directly cause changes in light intensity, such as light intensity, illumination, radiation temperature measurement, gas composition analysis, etc; It can also be used to detect other non electric quantities that can be converted into light quantity changes, such as part diameter, surface roughness, displacement, velocity, acceleration, object shape, working state identification, etc. Photosensitive sensors are widely used in industrial automatic control and intelligent robots because of their non-contact, fast response and reliable performance. Experiment items: 1. Understand the basic characteristics of the photoresistor, and measure its volt ampere characteristic curve and illumination characteristic curve. 2.
