Takardun Photoresistor
Photoresistor shine wani wurin kimiyya da yake amfani da shi a cikin zabe masu iya haɓaka da tsayi, kuma harufin zabe ta tana yi nasarar da rarrabbin tsayi. Idan tsayin ya zama mai karfi, harufin zabe ta tana rage, idan tsayin ya rage, harufin zabe ta tana karfi. Ba photoresistor ba na da alamomin faduwa, saboda haka za a amfani da abubuwan voltage a duk faduwar ita, kuma za a iya tabbatar da rarrabbin tsayi a kan magana da current a kan loop.

Amfani da Photoresistor
Security systems: Photoresistors can be used to detect the presence or absence of light, for example in camera meters, burglar alarms, or electronic eyes.
Lighting control: Photoresistors can be used to control the brightness or color of lights, such as street lighting, outdoor lighting.
Audio compression: Photoresistors can be used to smooth the response of an audio signal by reducing the dynamic range, such as in a compressor, limiter, or noise gate.
Optical communication: Photoresistors can be used to modulate or demodulate optical signals, such as optical cables, lasers, or photodiodes.
Measurement and instrumentation: Photoresistors can be used to measure or indicate light intensity, for example in photometers, spectrometers, or photometers.
