SIMPLE AMBIENT LIGHT SENSOR

V diplomskem delu predstavimo razvoj preprostega merilnika ambientne svetlobe, zasnovanega na integriranem vezju dsPIC30F5011. Naprava deluje tako, da mikrokrmilnik najprej pridobi podatke s senzorja. Ti podatki se uporabijo pri izračunu osvetlitve, merjeno v luksih. Osvetlitev se nato pošlje računalniku preko vodila USB. V delu smo uspešno načrtovali in izdelali elektronsko vezje ter programsko opremo. Dobljene rezultate smo primerjali s profesionalno napravo. Ugotovili smo, da obe napravi vračata primerljive rezultate.The thesis presents the development of a simple ambienth light sensor, based on chip dsPIC30F5011. First the microcontroller obtains data from the sensor. These information are used to calculate exposure measured in lux Value is then sent to computer via USB cable. In the present work we have successfully desinged electroninc circuit and software for device. Results were compared with a professional device. We found that both devices are returning comparable results
