Description: digital light sensor price in bd

BH1750FVI GY30 Digital Light Intensity Sensor Module (Arduino) is a Digital Ambient Light Sensing IC Produced by Japan ROHM Semiconductor. Built-in 16-bit analog-to-digital converter can be directly output a digital signal without complex calculations. This product is in affordable price and best guarantee by Robo Tech Valley. In addition, our every products that we sell has a strict quality inspection. So that, If you want to buy our products, do not hesitate to add them to the cart and buy it. We are committee to providing you best products and services.

Features:(Digital Light Sensor price in bd)

• • I2C BI (f / s mode supporting)
  • Spectral responsibility close to human eye distinguish
  • Luminance to digital converter
  • Wide range and high resolution (1 – 65535 lx)
  • Low current by power down function
  • 50Hz / 60Hz Light noise reject-function
  • 1.8V Logic input interface
  • no need of any exterior component
  • Dependency on the light source is little (ex. incandescent lamp, fluorescent lamp, halogen lamp, white LED, Sun Light)
  • It is possible to select 2 type of I2 C slave-address
  • Adjustable measurement result for influence of optical window(It is possible to detect min. 0.11lx, max. 100000lx by using this function.)
  • Small measurement variation (+/- 20%)
  • The influence of infrared is very small

Introduction of Pins: Digital light sensor price in bd

Pin Introduction
GND	Connected to the cathode of the power supply
ADD	IIC address pin
SDA	I²C data
SCL	I²C clock
VCC	Connected to the anode of the power supply (3~5v)

Principle: digital light sensor price in bd

BH1750FVI Digital Light intensity Sensor
In addition, Indicating to the brightness of the luminous surface is in the unit of Kendra / square meter is the ratio of the luminous intensity of the luminous surface in the specified direction to the area of the luminous surface perpendicular to the specified direction.
For a diffused scattering surface, although the light intensity and luminous flux in each direction are different. The brightness in all directions is equal. So, The phosphor screen of the TV is similar to this kind of diffused surface. So that, if you are looking at the image from all directions has the same brightness sense. Different objects have different reflection or absorption coefficients to light.

Experimental Procedures for Arduino

Step 1: Connect the circuit:

#include <Wire.h>

// GY-30

// BH1750FVI

// in ADDR 'L' mode 7bit addr

#define ADDR 0b0100011

// addr 'H' mode

// #define ADDR 0b1011100

void setup() {

// put your setup code here, to run once:

Serial.begin(9600);

while (!Serial) {

; // wait for serial port to connect. Needed for Leonardo only

}

Wire.begin();

Wire.beginTransmission(ADDR);

Wire.write(0b00000001);

Wire.endTransmission();

}

void loop() {

// put your main code here, to run repeatedly:

int val = 0;

// reset

Wire.beginTransmission(ADDR);

Wire.write(0b00000111);

Wire.endTransmission();

Wire.beginTransmission(ADDR);

Wire.write(0b00100000);

Wire.endTransmission();

// typical read delay 120ms

delay(120);

Wire.requestFrom(ADDR, 2); // 2byte every time

for (val = 0; Wire.available() >= 1; ) {

char c = Wire.read();

//Serial.println(c, HEX);

val = (val << 8) + (c & 0xFF);

}

val = val / 1.2;

Serial.print("lx: ");

Serial.println(val);

Serial.println("OK");

delay(100);

}
