Solar position tracing sensor using thin film pattern of both-sided printed circuit board |
摘要 |
Provided is a solar position tracing sensor having a high resolving power by using a temperature coefficient and heat conductivity of fine patterns on a printed circuit board (PCB). The solar position tracing sensor is reliable and has a wide application ranges for both celestial and terrestrial applications. It can be produced in mass at cheep cost. The solar position tracing sensor includes: a light condenser for condensing and filtering sunlight; a PCB having light reception patterns on the top and bottom surfaces; a heat protection plate for preventing the temperature of the entire PCB from being increased; a reference voltage supplier for providing a reference voltage source to find out a specific light reception pattern whose temperature is increased from radiation of the sunlight; and a voltmeter for measuring alteration in voltage based on the alteration in a temperature coefficient of the light reception pattern with increased temperature.
