SI7050 yog lub ntsuas kub digital uas ua haujlwm ntawm I2C cov txheej txheem kev sib txuas lus thiab muab qhov tseeb siab tshaj qhov ua haujlwm tag nrho thiab qhov kub thiab txias. Qhov kev ntsuas siab ntawm qhov ntsuas tau yog los ntawm qhov tshiab teeb liab ua thiab analog tsim. Cov ntsuas no tau kos nrog lub cim xeeb on-chip uas khaws cov ntaub ntawv hu xov tooj uas pab txhawb nws txoj kev siv thoob plaws. Nov yog nws qhov ua qauv qhia nrog Arduino Nano.

Kauj Ruam 1: Yam Koj Xav Tau..

1. Arduino Nano

2. SI7050

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 kawg ntawm I2C cable rau SI7050 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 SI7050 tuaj yeem rub tawm los ntawm peb qhov chaw cia khoom github-DCUBE Store.

Nov yog qhov txuas rau tib yam:

github.com/DcubeTechVentures/SI7050/blob/master/Arduino/SI7050.ino

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.

TSI 7050

// Tus lej no yog tsim los ua haujlwm nrog SI7050_I2CS I2C Mini Module

#suav nrog

// SI7050 I2C chaw nyob yog 0x40 (64)

#define Ntxiv 0x40

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 kis tau tus mob

Wire.beginTransmission (Addr);

// Nres I2C kev xa mus

Wire.endTransmission ();

ncua (300);

}

void lub voj ()

{

unsigned int cov ntaub ntawv [2];

// Pib I2C kis tau tus mob

Wire.beginTransmission (Addr);

// Xa cov lus ntsuas ntsuas kub, TSIS MUAJ TSEV KAWM NTAWV

Hlau.write (0xF3);

// Nres I2C kev xa mus

Wire.endTransmission ();

ncua (500);

// Thov 2 bytes ntawm cov ntaub ntawv

Wire.requestFrom (Addr, 2);

// Nyeem 2 bytes ntawm cov ntaub ntawv

// temp msb, kub lsb

yog (Wire.available () == 2)

{

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

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

}

// Hloov cov ntaub ntawv

ntab temp = ((data [0] * 256.0) + data [1]);

ntab ctemp = ((175.72 * temp) / 65536.0) - 46.85;

ntab ftemp = ctemp * 1.8 + 32;

// Cov ntaub ntawv tso tawm rau tus saib xyuas

Serial.print ("Kub hauv Celsius:");

Serial.print (ctemp);

Serial.println ("C");

Serial.print ("Kub hauv Fahrenheit:");

Serial.print (ftemp);

Serial.println ("F");

ncua (500);

}

Kauj Ruam 4: Cov ntawv thov:

SI7050 tuaj yeem suav nrog hauv ntau lub tshuab suav nrog cov khoos phis tawj khoom siv, cov cuab yeej siv tau yooj yim thiab cov cuab yeej siv kho mob. Qhov ntsuas no tuaj yeem ua haujlwm nyob rau hauv cov thawv txias txias, cov khoom muaj nqis nrog rau ntau yam kev tswj hwm kev lag luam. Nws ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv roj teeb ib yam.
