Photosensitive diode sensor brightness sensor ARDUINO comp /intelligent car sersor module

Product Description

Photosensitive diode sensor brightness sensor ARDUINO comp /intelligent car sersor module

can detect the analog quantity of brightness output

can set the output digital value of some brightness value

sensitivity adjustable,reliable Performance

working voltage is 5V,digital value and analog quantity double output

This sensor uses photosensitive diode,good directionality and can sense the light of fixed direction

Port instruction:DO is digital value output,AO is analog quantity output

And there is fixed bolt hole,which is easy to install

Two modules Description
1 can detect the brightness of surrounding environment and the light intensity (with a photoresistor comparison, good directivity, can perceive the fixed direction of the light source)
2 adjustable sensitivity adjust the digital potentiometer (shown in blue)
3 Operating voltage 3.3V-5V
5 output the form of a analog voltage output
           b digital switching outputs (0 and 1)
A fixed bolt hole for easy installation
7 small plates PCB size: 3cm * 1.6cm

Three-module interface specification (4-wire)
1 VCC external 3.3V-5V voltage (can be directly connected to the 5v microcontroller and 3.3v microcontroller)
2 GND external GND
3 DO-board digital output interface (0 and 1)
4 AO-board analog output interface
Four instructions for use
Photodiode module is most sensitive to the ambient light, generally used to detect the brightness of the ambient light intensity, photoresistor sensor module Universal In most cases, the difference between the two is that photodiode module directional, can be perceived The fixed direction of the light source.
2 module in the light conditions or the light intensity of less than a set threshold, DO port outputs a high level, when the external environment when the light intensity exceeds the set threshold value, the module D0 output is low;
3 small plates digital outputs D0 can be directly connected with the microcontroller, microcontroller to detect high and low, and to detect environmental light intensity change;
4 board digital output DO OUR relay module can directly drive, which can be composed of a photoelectric switch;
5 small plates analog output AO OUR AD module connected through the AD converter, the ambient light intensity can get more precise values;

Five test instructions
Shop 51 development board and photodiode module testing
Wiring instructions:
The module VCC pick development board VCC
The module GND with development board GND
The connected VCC and GND, module power indicator will light
Module with a light source, the adjustment board blue potentiometer, until the board switch indicator light, and then hands over the photodiode module switch indicator will be off. Hands off switch indicator is lit again. This phenomenon is the light source can trigger module, so that the switch indicator lights.
High and low of the other information inside comes with a 51 program, used to detect the photodiode module digital interface D0
Specifically described as follows:
Wiring:
The module VCC pick development board VCC
The module GND with development board GND
Module D0 connected development board P0.1
SCM: STC89C52
Serial port to send data baud rate: 9600
Phenomenon: module light source trigger the serial constantly sending 01 simultaneous switching light;
      Module without triggering light source, serial port does not send data at the same time the switch lights off.
