About This Product
Students read the resistance with a multimeter or ohmmeter while changing the light falling on the sensor, then use the module in simple light-sensing circuits. It shows the principle behind automatic lighting and light-activated switches. Educational Instrument can dispatch the Photoresistor on base to laboratories in Malaysia, Eritrea, Kuwait, Australia, Georgia and Libya.
Frequently Asked Questions
How is the Photoresistor on base used?
Connect it to a multimeter or ohmmeter, or into a circuit with other base-mounted components, and vary the light to see the resistance change.
