HDC1000 yog lub ntsuas cua digital nrog cov ntsuas kub sib xyaw uas muab qhov ntsuas tau zoo heev ntawm lub zog qis heev. Cov cuab yeej ntsuas cov av noo raws li lub peev xwm tshiab sensor. Cov av noo thiab qhov ntsuas kub tau tsim los ntawm lub Hoobkas. Nws ua haujlwm tsis pub dhau -40 ° C txog +125 ° C kub ntau.

Hauv qhov kev qhia no kev cuam tshuam ntawm HDC1000 sensor module nrog cov duab photon tau piav qhia. Txhawm rau nyeem qhov ntsuas kub thiab qhov av noo, peb tau siv cov khoom me me nrog I2c adapter. Qhov I2C adapter ua rau kev txuas mus rau lub ntsuas qhov ntsuas tau yooj yim thiab ntseeg tau ntau dua.

Kauj Ruam 1: Yuav Tsum Kho Vajtse:

Cov ntaub ntawv uas peb xav tau kom ua tiav peb lub hom phiaj suav nrog cov khoom siv hauv qab no:

1. HDC1000

2. Particle Photon

3. I2C Cable

4. I2C Shield rau particle photon

Kauj ruam 2: Khoos phis tawj sib txuas:

Tshooj khoos phis tawj sib txuas ntu piav qhia qhov txuas txuas txuas uas xav tau ntawm lub sensor thiab cov duab photon. Ua kom muaj kev sib txuas raug yog qhov tseem ceeb xav tau thaum ua haujlwm ntawm ib qho system rau qhov xav tau cov zis. Yog li, qhov xav tau kev sib txuas yog raws li hauv qab no:

HDC1000 yuav ua haujlwm dhau I2C. Nov yog qhov piv txwv kab hluav taws xob daim duab, qhia txog yuav ua li cas xaim txhua lub interface ntawm lub sensor.

Tawm-ntawm-lub thawv, lub rooj tsavxwm tau teeb tsa rau I2C interface, zoo li peb pom zoo siv qhov kev sib txuas no yog tias koj tsis ntseeg lwm yam.

Txhua yam koj xav tau yog plaub lub xov hlau! Tsuas yog plaub qhov kev sib txuas xav tau Vcc, Gnd, SCL thiab SDA tus pin thiab cov no txuas nrog kev pab ntawm I2C cable.

Cov kev sib txuas no tau qhia hauv cov duab saum toj no.

Kauj Ruam 3: Txoj Cai ntsuas Kub thiab Vaum:

Cia peb pib nrog cov lej me me tam sim no.

Thaum siv lub ntsuas qhov ntsuas nrog qhov me me, peb suav nrog application.h thiab lub tsev qiv ntawv spark_wiring_i2c.h. "application.h" thiab lub tsev qiv ntawv spark_wiring_i2c.h muaj cov haujlwm uas pab txhawb kev sib txuas lus i2c ntawm lub sensor thiab cov khoom me me.

Tag nrho cov cai hauv qab no tau muab rau hauv qab no kom yooj yim ntawm tus neeg siv:

#suav nrog

#suav nrog

// HDC1000 I2C chaw nyob yog 0x40 (64)

#define Ntxiv 0x40

ob cTemp = 0.0, fTemp = 0.0, av noo = 0.0;

int temp = 0, hum = 0;

void teeb tsa ()

{

// Teem sib txawv

Particle.variable ("i2cdevice", "HDC1000");

Particle.variable ("av noo", av noo);

Particle.variable ("cTemp", cTemp);

// Pib I2C kev sib txuas lus

Hlau.begin ();

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

Serial.begin (9600);

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xaiv cov npe sau npe

Hlau.write (0x02);

// Kub, ua kom cov av noo, daws teeb meem = 14-ntsis, rhaub rau

Hlau.write (0x30);

// Nres I2C Kev Kis

Wire.endTransmission ();

ncua (300);

}

void lub voj ()

{

unsigned int cov ntaub ntawv [2];

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xa cov lus ntsuas ntsuas ntsuas

Hlau.write (0x00);

// Nres I2C Kev Kis

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

temp = ((cov ntaub ntawv [0] * 256) + cov ntaub ntawv [1]);

cTemp = (temp / 65536.0) * 165.0 - 40;

fTemp = cTemp * 1.8 + 32;

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xa cov lus ntsuas ntsuas av noo

Hlau.write (0x01);

// Nres I2C Kev Kis

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

hum = ((cov ntaub ntawv [0] * 256) + cov ntaub ntawv [1]);

av noo = (hum / 65536.0) * 100.0;

// Tso tawm cov ntaub ntawv rau dashboard

Particle.publish ("Tus txheeb ze Vaum:", Txoj hlua (av noo));

ncua (1000);

Particle.publish ("Kub hauv Celsius:", String (cTemp));

ncua (1000);

Particle.publish ("Kub hauv Fahrenheit:", String (fTemp));

ncua (1000);

}

Particle.variable () muaj nuj nqi tsim cov kev hloov pauv kom khaws cov zis tawm ntawm lub sensor thiab Particle.publish () muaj nuj nqi qhia cov zis ntawm lub dashboard ntawm lub xaib.

Cov zis sensor tau pom hauv daim duab saum toj no rau koj siv.
