BH1715 yog digital Ambient Light Sensor nrog I²C tsheb npav sib cuam tshuam. BH1715 feem ntau yog siv kom tau txais cov ntaub ntawv teeb pom kev zoo los kho LCD thiab Keypad lub teeb pom kev zoo rau lub xov tooj ntawm tes. Cov cuab yeej no muaj 16-ntsis kev daws teeb meem thiab ntsuas ntsuas tau ntau, tso cai kuaj pom los ntawm.23 txog 100, 000 lux. Nov yog nws qhov ua qauv qhia nrog Arduino nano.

Kauj Ruam 1: Yam Koj Xav Tau..

1. Arduino nano

2. HLB 1715

3. I²C Cable

4. I²C Shield rau Arduino Nano

Kauj Ruam 2: Kev Sib Txuas:

Siv daim I2C daim thaiv rau Arduino Nano thiab maj mam thawb nws hla tus pin ntawm Nano.

Tom qab ntawd txuas ib qho kawg ntawm I2C cable rau BH1715 sensor thiab lwm qhov kawg rau I2C daim ntaub thaiv.

Kev sib txuas tau qhia hauv daim duab saum toj no.

Kauj ruam 3: Code:

Tus lej Arduino rau BH1715 tuaj yeem rub tawm los ntawm peb GitHub chaw cia khoom-Dcube Store.

Nov yog qhov txuas rau tib yam:

github.com/DcubeTechVentures/BH1715…

Peb suav nrog tsev qiv ntawv Wire.h los pab txhawb I2c kev sib txuas lus ntawm lub sensor nrog Arduino board.

Koj tseem tuaj yeem luam cov cai los ntawm no, nws tau muab raws li hauv qab no:

// Faib nrog daim ntawv tso cai yuav dawb.

// Siv nws txhua txoj hauv kev uas koj xav tau, muaj txiaj ntsig lossis pub dawb, muab nws haum rau hauv daim ntawv tso cai ntawm nws cov haujlwm ua haujlwm.

SWB 1715 Stb

// Cov cai no tau tsim los ua haujlwm nrog BH1715_I2CS I2C Mini Module muaj nyob hauv Dcube Store.

#suav nrog

// BH1715 I2C chaw nyob yog 0x23 (35)

#define Ntxiv 0x23

void teeb tsa ()

{

// Pib I2C kev sib txuas lus li MASTER

Hlau.begin ();

// Initialise Serial Communication, teeb baud tus nqi = 9600

Serial.begin (9600);

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xa lub zog ntawm kev hais kom ua

Hlau.write (0x01);

// Nres I2C Kev Kis

Wire.endTransmission ();

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xa cov lus ntsuas ntsuas mus tas li

Hlau.write (0x10);

// Nres I2C Kev Kis

Wire.endTransmission ();

ncua (300);

}

void lub voj ()

{

unsigned int cov ntaub ntawv [2];

// Thov 2 byte ntawm cov ntaub ntawv

Wire.requestFrom (Addr, 2);

// Nyeem 2 bytes ntawm cov ntaub ntawv

// ALS msb, ALS lsb

yog (Wire.available () == 2)

{

cov ntaub ntawv [0] = Wire.read ();

cov ntaub ntawv [1] = Wire.read ();

}

ncua (300);

// hloov cov ntaub ntawv

ntab luminance = ((cov ntaub ntawv [0] * 256) + cov ntaub ntawv [1]) / 1.20;

// Cov ntaub ntawv tso tawm rau tus saib xyuas

Serial.print ("Ambient Light Luminance:");

Serial.print (luminance);

Serial.println ("lux");

}

Kauj Ruam 4: Cov ntawv thov:

BH1715 yog lub teeb pom kev ib puag ncig lub teeb pom kev zoo uas tuaj yeem suav nrog hauv xov tooj ntawm tes, LCD TV, NCEJ PC thiab lwm yam. siv lub teeb pom kev zoo.
