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.

Yadda Photoresistor Yake Iya Haɓaka Da Tsayi

Yadda photoresistor yake iya haɓaka da tsayi tana da yawa a cikin zabe masu iya haɓaka da tsayi. Wannan tana faruwa a lokacin da materialin yake samu photons (zabe masu iya haɓaka da tsayi) da yake da karfi mai yawa. Idan tsayin ya zama mai karfi, photons suna gudanar da electrons a kan layin valence (layin gajerar atom), kuma suna haɗa zuwa layin conduction. Wannan tana bincike mafi yawan free electrons da holes don magana da current, kuma tana rage harufin zabe ta photoresistor.

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.
