Photo transistor is a type of transistor whose base bias is infrared light. The amount of current flowing between the collector and the emitter is proportional to the intensity of light received by the photo transistor. Photo transistors are often used as an infrared light control switch, which utilizes saturation (saturation) and off (cut off) conditions from the photo transistor. ...

Sensor Photo Transistor
Photo transistor merupakan jenis transistor yang bias basisnya berupa cahaya infra merah. Besarnya arus yang mengalir di antara kolektor dan emitor sebanding dengan intensitas cahaya yang diterima photo transistor tersebut. Photo transistor sering digunakan sebagai saklar terkendali cahaya infra merah, yaitu memanfaatkan keadaan jenuh (saturasi) dan mati (cut off) dari photo transistor tersebut. Prisip kerja photo transistor untuk menjadi saklar ...
