Product performance:
1.whenAmbient lightNo light orThe brightness does not reach the set thresholdWhen DO is lost OutHigh level, When the external environmentThe light brightness exceeds the set thresholdWhen DO End outputLow levelTheDetectionbrightnessCan be adjusted by potentiometer,On time needleAdjust the potentiometer, detectbrightnessincrease;CounterclockwiseAdjust the potentiometer, detectbrightness cut back

2.TheComparator output, signal clean, good waveform, drive ability, more than15mA.

3.TheSensor module output port OUT can be directly connected with the microcontroller IO port that is
Yes, you can also drive a 5V relay directly; Connection: VCC-VCC; GND-GND; OUT-IO

4, can be used 3.3 V-5V DC power supply to the module. When the power supplyTurn on Time,redThe power light is on;

Instructions for use:
1.TheVCC external 3.3V-5V voltage (can be directly with the 5v microcontrolleror3.3v single-chip connected)
2.TheGND External GND
3.TheDODigital output interface (0 and 1)
4.TheAODigital output interfaceAnalog quantity)

Package includes
1pcs photodiode module
