Abstract:

 

The light sensitive circuit elements, in line with the changes in the amount of light, produce electrical values such as current, voltage and resistance change. Thus, these elements are being used in light measurement, light control and light detection systems. In this research, the Phototransistor and LDR  light dependent resistor , which are commonly used in light detection systems, have been exposed to different lighting values in an indoor environment. Their electrical reaction values have been measured and sensitivity analysis has been conducted. In the light of the findings obtained, it has been seen that with 134.23 standard deviation rate Phototransistor has shown more light sensitivity than LDR.

 

Işığa duyarlı devre elemanları, ışık miktarındaki değişime bağlı olarak akım, gerilim ve direnç değişimi gibi elektriksel değerler üretirler. Bu sayede bu elemanlar ışık ölçüm, ışık kontrol, ışık algılama sistemlerinde kullanılırlar. Bu çalışmada ışık algılama sistemlerinde yaygın kullanıma sahip Fototransistör ve LDR  ışığa bağlı direnç  kapalı ortamda değişken ışık değerlerine maruz bırakılarak elektriksel cevap değerleri ölçülmüş hassasiyet analizi yapılmıştır, elde edilen değerler göz önünde bulundurulduğunda fototransistör 134.23 standart sapma değeri ile LDR den yüksek ışığa duyarlılık gösterdiği belirlenmiştir.
