TMP100 High-Accuracy, Low-Power, Digital Kub Sensor I2C MINI module. TMP100 yog qhov zoo tshaj rau kev ntsuas kub ntxiv. Cov cuab yeej no muab qhov tseeb ntawm ± 1 ° C yam tsis tas yuav ntsuas qhov ntsuas lossis sab nrauv tiv thaiv teeb liab. Nov yog qhov ua piv txwv nrog Particle photon.

Kauj Ruam 1: Yam Koj Xav Tau..

1. Particle Photon

2. TMP100

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 qho kawg ntawm I2C cable rau TMP100 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 TMP100 tuaj yeem rub tawm los ntawm peb GitHub chaw cia khoom- Dcube Store

Nov yog qhov txuas rau tib yam:

github.com/DcubeTechVentures/TMP100…

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.

TSO 100

// Cov cai no tau tsim los ua haujlwm nrog TMP100_I2CS I2C Mini Module muaj nyob hauv Dcube Store.

#suav nrog

#suav nrog

// TMP100 I2C chaw nyob yog 0x4F (79)

#define Ntxiv 0x4F

ntab cTemp = 0, fTemp = 0;

void teeb tsa ()

{

// Teem sib txawv

Particle.variable ("i2cdevice", "TMP100");

Particle.variable ("cTemp", cTemp);

// Pib I2C kev sib txuas lus li MASTER

Hlau.begin ();

// Initialise Serial kev sib txuas lus, teeb baud tus nqi = 9600

Serial.begin (9600);

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xaiv cov npe sau npe

Hlau.write (0x01);

// Teeb tsa kev hloov pauv tas li, hom sib piv, 12-ntsis kev daws teeb meem

Hlau.write (0x60);

// Nres I2C Kev Kis

Wire.endTransmission ();

ncua (300);

}

void lub voj ()

{

unsigned int cov ntaub ntawv [2];

// Pib I2C Kev Kis

Wire.beginTransmission (Addr);

// Xaiv cov ntaub ntawv sau npe

Hlau.write (0x00);

// Nres I2C Kev Kis

Wire.endTransmission ();

// Thov 2 bytes ntawm cov ntaub ntawv

Wire.requestFrom (Addr, 2);

// Nyeem 2 bytes ntawm cov ntaub ntawv

// cTemp msb, cTemp lsb

yog (Wire.available () == 2)

{

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

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

}

// Hloov cov ntaub ntawv

cTemp = (((cov ntaub ntawv [0] * 256) + (data [1] & 0xF0)) / 16) * 0.0625;

fTemp = cTemp * 1.8 + 32;

// Tso tawm cov ntaub ntawv rau dashboard

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

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

ncua (1000);

}

Kauj Ruam 4: Cov ntawv thov:

Ntau daim ntawv thov suav nrog TMP100 lub zog qis, qhov tseeb cov ntsuas hluav taws xob suav nrog Lub Hwj Huam Saib Xyuas Kub Kub, Khoos phis tawj Ib puag ncig tiv thaiv cua sov, Kev tswj roj teeb nrog rau lub tshuab ua haujlwm.
