Light dependent resistor is made of semi conductor material, and the conductance changs with light. Accoring to this characteristic, LDR photoelectric resistor can be produced with different figures and illuminated areas. LDR electricalr, which is also called LDR photocell or photocell sensor, is widelyd used in many industries, such as toys, lamps, camera, etc.
The light sensor is a device which converts light energy of various wavelengths from infrared to UV into the electrical energy(or to an electrical signal). This is the reason why they are named as photoelectric devices. They sense the light during this process, and so can be called as 'photo sensors'.
The light sensor is a passive devices that convert this "light energy" whether visible or in the infra-red parts of the spectrum into an electrical signal output. Light sensors are more commonly known as "Photoelectric Devices" or "Photo Sensors" because the convert light energy (photons) into electricity (electrons).
What is ldr sensor and what are ldrs used for or history of ldr? Senba Sensing Technology Co.,Ltd. is a professional ldr manufacturers, we provide pir sensor chip, pir am312 datasheet, am312 pir datasheet for our customers, want to know more, please contact us..
