Description
Analog Digital Output 4 Pins CdS Photoresistor Light Brightness Detection Sensor Module Arduino
Feature
1.Pins: 4(VCC, GND, DO, AO);
2.Output: Digtal(DO) and Analog(AO);
3.Detection Threshold Adjustable;
4.Operating Principle:
DO High(when brightness lower than threshold),
DO Low(when brightness higher than threshold);
AO(voltage on the photoresistor)—Rp(photoresistor value)=(Vao*10K)/(Vcc-Vao);
Electrical
1.Operating Voltage: 3.3V~5V;
2.DO Driving Capacity: ≥15mA(LM393 comparator output);
Mechanical
1.PCB Size: 32mmx14mm;
2.With Mounting Hole;
