HIH6130 yog qhov ntsuas cua thiab ntsuas kub nrog cov zis digital. Cov ntsuas no muab qib raug ntawm ± 4% RH. Nrog kev lag luam-ua kom muaj kev ruaj ntseg mus sij hawm ntev, qhov tseeb kub-them nyiaj digital I2C, Kev lag luam ua rau muaj kev ntseeg siab, Kev siv hluav taws xob zoo thiab Ultra-pob me me qhov loj me thiab xaiv.

Hauv qhov kev qhia no kev cuam tshuam ntawm HIH6130 sensor module nrog raspberry pi tau pom thiab nws cov phiaj xwm siv Java lus kuj tseem tau piav qhia. Txhawm rau nyeem qhov ntsuas kub thiab av noo, peb tau siv raspberry pi nrog I2C adapter Qhov no 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. HH6130

2. Raspberry Pi

3. I2C Cable

4. I2C Shield rau raspberry pi

5. Ethernet Cable

Kauj ruam 2: Khoos phis tawj sib txuas:

Tshooj khoos phis tawj sib txuas ntu piav qhia qhov txuas txuas uas xav tau ntawm lub ntsuas cua thiab raspberry pi. 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:

HIH6130 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 rau Kev Ntsuas thiab Kev Ntsuas Kub:

Qhov zoo ntawm kev siv raspberry pi yog, uas muab rau koj hloov pauv ntawm cov lus programming uas koj xav tau los teeb tsa lub rooj tsav xwm txhawm rau txhawm rau cuam tshuam lub sensor nrog nws. Kev siv cov txiaj ntsig zoo ntawm pawg no, peb tab tom qhia ntawm no nws tau ua haujlwm hauv Java. Tus lej java rau HIH6130 tuaj yeem rub tawm los ntawm peb cov zej zog GitHub uas yog Dcube Store.

Ntxiv rau qhov yooj yim ntawm cov neeg siv, peb tab tom piav qhia cov cai ntawm no thiab:

Raws li thawj kauj ruam ntawm kev sau npe, koj yuav tsum rub lub pi4j lub tsev qiv ntawv thaum java vim tias lub tsev qiv ntawv no txhawb nqa cov haujlwm siv hauv txoj cai. Yog li, txhawm rau rub lub tsev qiv ntawv koj tuaj yeem mus ntsib qhov txuas hauv qab no:

pi4j.com/install.html

Koj tuaj yeem luam qhov ua haujlwm java code rau lub ntsuas no los ntawm no kuj:

ntshuam com.pi4j.io.i2c. I2CBus;

ntshuam com.pi4j.io.i2c. I2CDevice;

ntshuam com.pi4j.io.i2c. I2CFactory;

ntshuam java.io. IOException;

pej xeem chav kawm HIH6130

pej xeem zoo li qub tsis muaj dab tsi tseem ceeb (Txoj hlua args ) cuam tshuam zam

{

// Tsim I2C npav

I2CBus Bus = I2CFactory.getInstance (I2CBus. BUS_1);

// Tau txais I2C ntaus ntawv, HIH6130 I2C chaw nyob yog 0x27 (39)

I2CDevice ntaus ntawv = Bus.getDevice (0x27);

Xov.sleep (500);

// Nyeem 4 bytes ntawm cov ntaub ntawv

// humidity msb, humidity lsb, temp msb, temp lsb

byte cov ntaub ntawv = tshiab byte [4];

device.read (0x00, cov ntaub ntawv, 0, 4);

// Hloov cov ntaub ntawv mus rau 14-ntsis

ob npaug av noo = (((data [0] & 0x3F) * 256) + (data [1] & 0xFF)) / 16384.0 * 100.0;

int temp = (((cov ntaub ntawv [2] & 0xFF) * 256) + (data [3] & 0xFC)) / 4);

ob cTemp = (temp / 16384.0) * 165.0 - 40.0;

ob fTemp = cTemp * 1.8 + 32;

// Cov ntaub ntawv tso tawm rau lub vijtsam

System.out.printf ("Tus txheeb ze Vaum: %.2f %% RH %n", av noo);

System.out.printf ("Kub hauv Celsius: %.2f C %n", cTemp);

System.out.printf ("Kub hauv Farhenheit: %.2f F %n", fTemp);

}

}

Lub tsev qiv ntawv uas txhawb nqa i2c kev sib txuas lus ntawm lub sensor thiab pawg thawj coj yog pi4j, nws ntau pob khoom I2CBus, I2CDevice thiab I2CFactory pab tsim kom muaj kev sib txuas.

ntshuam com.pi4j.io.i2c. I2CBus; ntshuam com.pi4j.io.i2c. I2CDevice; ntshuam com.pi4j.io.i2c. I2CFactory; ntshuam java.io. IOException;

sau () thiab nyeem () lub luag haujlwm tau siv los sau qee cov lus txib tshwj xeeb rau lub ntsuas cua kom nws ua haujlwm hauv ib qho tshwj xeeb thiab nyeem cov ntawv tso tawm feem.

Qhov tso tawm ntawm lub sensor kuj tseem muaj nyob hauv daim duab saum toj no.

Kauj Ruam 4: Cov ntawv thov:

HIH6130 tuaj yeem siv los muab cov txheeb ze txheeb ze txheeb xyuas qhov kub thiab txias hauv cov cua txias, nkag siab lub cev, ntsuas cua sov, ua kom cua txias/de-humidifiers, thiab humidistats kom muaj kev nyob nyab xeeb. Nws kuj tseem tuaj yeem ua haujlwm hauv cov tshuab cua, cov chaw huab cua thiab cov khoom sib tham hauv xov tooj.
