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. Nov yog nws qhov ua piv txwv nrog raspberry pi siv java code.

Kauj Ruam 1: Yam Koj Xav Tau..

1. Raspberryy Pi

2. HIH6130

3. I²C Cable

4. I²C Shield rau Raspberry Pi

5. Ethernet Cable

Kauj Ruam 2: Kev Sib Txuas:

Siv daim I2C daim thaiv rau raspberry pi thiab maj mam thawb nws hla gpio pins ntawm raspberry pi.

Tom qab ntawd txuas ib qho kawg ntawm I2C cable rau HIH6130 sensor thiab lwm qhov kawg rau I2C daim ntaub thaiv.

Kuj txuas Ethernet cable rau pi lossis koj tuaj yeem siv WiFi module.

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

Kauj ruam 3: Code:

Tus lej java rau HIH6130 tuaj yeem rub tawm los ntawm peb GitHub chaw cia khoom- Dcube Store

Nov yog qhov txuas rau tib yam:

Peb tau siv pi4j tsev qiv ntawv rau java code, cov kauj ruam rau nruab pi4j ntawm raspberry pi tau piav qhia ntawm no:

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.

TIAB SA 6130

// Cov cai no tau tsim los ua haujlwm nrog HIH6130_I2CS I2C Mini Module muaj nyob hauv Dcube Store.

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);

}

}

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.
