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. Nov yog nws qhov ua piv txwv nrog particle photon.

Kauj Ruam 1: Yam Koj Xav Tau..

1. Particle Photon

2. HDC1000

3. I²C Cable

4. I²C Shield rau Particle Photon

Kauj Ruam 2: Kev Sib Txuas:

Nqa daim I2C daim ntaub thaiv rau cov photon me me thiab maj mam thawb nws hla cov pins ntawm cov khoom sib nqus.

Tom qab ntawd txuas ib kawg ntawm I2C cable rau HDC1000 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:

Cov lej me me rau HDC1000 tuaj yeem rub tawm los ntawm peb GitHub chaw cia khoom- Dcube Store.

Nov yog qhov txuas rau tib yam:

github.com/DcubeTechVentures/HDC1000…

Cov ntawv ntawm HDC1000 tuaj yeem pom ntawm no:

www.ti.com.cn/cn/lit/ds/symlink/hdc1000.pdf

Peb tau siv ob lub tsev qiv ntawv rau cov lej me me, uas yog application.h thiab spark_wiring_i2c.h. Spark_wiring_i2c lub tsev qiv ntawv xav tau los pab txhawb I2C kev sib txuas lus nrog lub sensor.

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.

// HDC1000

// Cov cai no tau tsim los ua haujlwm nrog HDC1000_I2CS I2C Mini Module muaj nyob hauv Dcube Store.
