High Quality Diam 7mm Light Resistor for Outdoor Solar Garden Light GL7537-1

Overview
A ldr smd 0805 photoresistor (or light-dependent resistor, LDR, or photo-conductive cell) is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity; in other words, it exhibits photoconductivity. A photoresistor can be applied in light-sensitive detector circuits, and light-activated and dark-activated switching circuits. There are 3mm, 4mm, 5mm, 7mm, 10mm, 12mm, 20mm for your choose.

Design Considerations
Photoresistors are less light-sensitive devices than photodiodes or phototransistors: the two latter components are true semiconductor devices, while a photoresistor is a passive component and does not have a PN-junction. The photoresistivity of any photoresistor may vary widely depending on ambient temperature, making them unsuitable for applications requiring precise measurement of or sensitivity to light photons.
Applications
Photoresistors come in many types. Inexpensive cadmium sulfide cells can be found in many consumer items such as camera light meters, clock radios, alarm devices (as the detector for a light beam), nightlights, outdoor clocks, solar street lamps and solar road studs, etc.
FAQ
1.What is an LDR (Light Dependent Resistor)?
An LDR is a component that has a (variable) resistance that changes with the light intensity that falls upon it. This allows them to be used in light sensing circuits.
Owning very strong R&D Center, Senba can research and develop the pyroelectric infrared sensor independently. Among those pir sensor manufacturers, Senba Sensor has become the first owner of this special technology enterprise in China. We are awarded as "Henan high-tech enterprises" in 2006 and awarded as "Notional high-tech enterprises" in 2012.
