Photosensitive Sensor Module with 3-Pin Cable Arduino Compatible
Photosensitive Sensor Module with 3-Pin Cable Arduino Compatible, Arduino-Compatible Photosensitive Sensor Module with 3-Pin Cable Now you can measure light levels with this sensor module. This module uses a Light Dependant Resistor (LDR), or Cadmium Sulfide (CdS) photocell, to produce an output voltage that varies with light level. Connect it directly to your Arduino to build a night or day sensor, a sun tracker or combine it with a laser module to make a laser trip wire. Specifications Operating Voltage: 3.3 VDC or 5 VDC Output : Analog voltage Pull-Down resistor: 10 K., on board Dimensions: 0.98" x 0.59" (25 x 15 mm) Difficulty: Level 3 (intermediate)
