Light Detection 4-Pin 2-Channel Photo Diode Sensor Module - Blue
Quantity: 1- Color: Blue- Material: PCB board- Working voltage: 3.3V~12V- Current: Over 15mA- Output: Digit switch output (0£¬ 1)- Uses wide voltage LM393 comparator- Indicator light for indicating switch and power.- Using photoconductive resistance sensor- Sensitive to light£¬ it's often used to test light brightness around - Universal use with photo resistor sensor module- When environment light brightness can't reach the set range£¬ the output is high; when it over the set range£¬ the output is low- Directly connected to microcontroller£¬ testing environment light brightness- Drive relay module directly via output port£¬ which can be composed of a light control switch
