Product Details

A photoresistor or light-dependent resistor (LDR) or photocell 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- and dark-activated switching circuits.





Applicaation:





-Camera light meters, clock radios, alarm devices (as the detector for a light beam), night lights, outdoor clocks, solar street lamps and solar road studs





-Photoresistors can be placed in streetlights to control when the light is on. Ambient light falling on the photoresistor causes the streetlight to turn off. Thus energy is saved by ensuring the light is only on during hours of darkness.





-They are also used in some dynamic compressors together with a small incandescent or neon lamp, or light-emitting diode to control gain reduction.





Features:
- Maximum Voltage: 150 Volt DC
- Maximum Wattage: 90 mW
- Operating Temperature: -30c ~ 70c
- Spectral Peak: 540nm
- Light Resistance: 0.5 Mohm
- Responsive Time: Up:20 Down:30
- Illumination Resistance Characteristics:4
- The photoresistors are a staple of electronics
- Great tool to check the level of ambient light
- As the light on the sensor increases, the resistance across the two leads decreases
- Works great with both arduino boards and Raspberry Pie
