uxcell Photosensitive Diode Sensor 4 Terminals Light Detection Photodiode Module for Arduino Smart Car

Great Sensors for Smart Car Arduino Project. Having Fun With Electronics and Programming! Description: Photodiode module is most sensitive to environmental light intensity , generally used for detecting the ambient brightness and light intensity. Compared with Photosensitive Resistance Sensor, this module has better directionality, can sense light in a certain direction. When ambient light intensity does not reach the threshold value, the module DO port output high lever; when the ambient light intensity exceeds a set threshold, the D0 output low lever. Sensitivity Adjustable. Increases detection brightness by adjusting the potentiometer clockwise and decreases by adjusting the potentiometer counterclockwise. Wiring Instructions: VCC ---- "+" GND ---- "-" DO ---- TTL Signal Output AO ---- Analog Signal Output Specification: Working Voltage: 3.5V-5.5V PCB Size: 31mm x 14mm (L*W) Pin Quantity: 4 Pin Distance: 2.54m Fixed Hole Dia: 3mm Package Includes: 1 x Photodiode Sensor
