The datasheetarchive datasheet search engine author. Ldr dapat digunakan sebagai indikator pengukuran sensor cahaya yang dapat dimanfaatkan untuk otomasi elektronika. A photoresistor or ldr light dependent resistor, as the name suggests will change it resistance based on the light around it. Ldr datasheet electrical resistance and conductance lighting. The cell resistance falls with increasing light intensity. Overview pir sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. Scribd is the worlds largest social reading and publishing site.
The light sensor is connected to the analogue inputs of the arduino. The light dependent resistor ldr is just another special type of resistor and hence has no polarity. Ldr datasheet, ldr pdf, ldr data sheet, ldr manual, ldr pdf, ldr, datenblatt, electronics ldr, alldatasheet, free, datasheet, datasheets, data sheet, datas sheets. They are breadboard friendly and can be easily used on a perf board also. The cadmium sulfide cds or light dependent resistor ldr whose resistance is inversly dependent on the amount of light falling on it, is known by many. One of the pins of the ldr is connected to the ground while the other is connected to one of the 5 analogue in pins. Ldr datasheet electrical resistance and conductance. Depending on the function of the ldr it may need another resistor connected to it. Ldr datasheet, ldr pdf, ldr data sheet, datasheet, data sheet, pdf. Applications include smoke detection, automatic lighting control, batch counting and burglar alarm systems.

Datasheet search engine for electronic components and semiconductors.
A light sensor or ldr can be very easily interfaced with an arduino. Two cadmium sulphidecds photoconductive cells with spectral responses similar to that of the human eye. Light dependent resistor ldr applications electrical. Gl5516 datasheet light dependent photoresistor, gl5516 pdf, gl5516 pinout, gl5516 manual, gl5516 schematic, gl5516 equivalent. This material copyrighted by its respective manufacturer. The cadmium sulfide cds or light dependent resistor ldr whose resistance is inversly dependent on the amount of light falling on it, is known by many names including the photo resistor, photoresistor, photoconductor, photoconductive cell, or simply the photocell. The symbol for ldr is just as similar to resistor but adds to inward arrows as shown above.
