5800B Light Dependent Resistor (LDR) White Color

Basic Electronic Components, Electronic Components, Resistor5800B Light Dependent Resistor (LDR) White Color
The 5800B Light Dependent Resistor (LDR) White Color is a photoresistor (or light-dependent resistor, LDR, or photo-conductive cell). Which 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 is made of a high resistance semiconductor.
Photoresistors are Semiconductor devices that use light energy to control the flow of electrons, and hence the current flowing through them. When the light level decreases, the resistance of the LDR increases. As this resistance increases in relation to the other Resistor; which has a fixed resistance, it causes the voltage dropped across the LDR to also increase. When this voltage is large enough (0.7V for a typical NPN Transistor), it will cause the Transistor to turn on.
when the light falls on its surface, then the material conductivity reduces and also the electrons in the valence band of the device are excited to the conduction band.
Note:Â Color of product may vary, you may get available color.
Features :
- Dark resistance:> 200 MΩ, corresponding to dark current.
- Light Resistance: <2.4KΩ, corresponding to light current.
- High sensitivity.
- The current = Light current – dark current.
- Diameter: 5mm.

Basic Electronic Components5A Constant Current / Voltage LED Drives Lithium Battery Charging Module
This Buck converter can be used as a normal step-down module with overcurrent protection capability for various applications. It is used as a charger for various voltage lithium batteries, batteries, nickel-cadmium nickel-hydrogen batteries (battery packs), for solar panels, wind turbines, etc. This buck converter can also be used as a high-power LED driver module.
The module comes with two modes of constant voltage and constant current, and there are indicators to indicate which mode the module is currently in. When used as a lithium battery charger, you can set the float voltage and charge current to show it is charging or already full. With current limiting protection, the module will not burn out even if the output is short-circuited.
Note: The capacitor component’s voltage & capacitance parameters may vary as per circuit design.

5mm LDR (Pack of 10)
This LDR 5mm changes resistance with the change in the ambient light exposure on the surface of the sensor. LDR (Light Dependent Resistor) is a type of photocell which finds excellent use in light sensing device application, whether it is automatic outdoor light ON/OFF switch or Indoor automatic light switch.
The LDR 5mm sensor works best in both Light and dark regions. Light-dependent resistors or photoresistors are a staple of electronics. If you need a way to sense the level of ambient light then there is no easier way to do it. As the light on the sensor increases then the resistance across the two leads decreases.
Two Cadmium Sulphide (CDs) PhotoConductive Cells with spectral responses similar to that of the human eye. Cell resistance falls with increasing light intensity. Applications of this product include smoke detection, Automatic lighting control, batch counting, and burglar alarm systems.
