Description

 

  Photodiode moduleThe most sensitive to ambient light intensity, generally used to detect the surrounding environment, brightness and light intensity, in most cases canAnd photosensitive sensor module common, The difference between the two,Photodiode module direction is better, you can sense the fixed direction of the light sourceThe

The sensor module to adapt to the ambient light, the use of photodiode sensor for ambient light detection, the module in the ambient lightNo light orbrightThe threshold can not be set, DO outputHigh level, When the external environmentThe light brightness exceeds the set threshold, DO outputLow level, The operating voltage is 3.3V-5V. The brightness of the sensor can be adjusted by the potentiometer. Photoresistor module is the most sensitive to ambient light, generally used to detect the ambient light intensity, trigger single-chip or relay modules. DO output can directly drive the shop relay module, which can form a light control switch.

 

Product performance:

 

1.whenAmbient lightNo light orThe brightness does not reach the set thresholdWhen DO is lost

2TheComparator output, signal clean, good waveform, drive ability, more than

15mA.

3TheSensor 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;
