AMS5812 Amplified Pressure Sensor nrog Analog thiab Digital Outputs yog lub ntsuas qhov ntsuas siab nrog qhov tso tawm qhov hluav taws xob analog thiab digital I2C interface. Nws ua ke lub piezoresistive sensing element nrog lub teeb pom kev zoo rau nws txoj haujlwm. Nov yog nws qhov ua qauv qhia nrog arduino nano.

Kauj Ruam 1: Yam Koj Xav Tau..

1. Arduino Nano

2. AMS5812_0050-D-B

3. I²C Cable

4. I2C Shield rau Arduino Nano

Kauj Ruam 2: Kev Sib Txuas:

Siv daim I2C daim thaiv rau Arduino Nano thiab maj mam thawb nws hla tus pin ntawm Nano.

Tom qab ntawd txuas ib qho kawg ntawm I2C cable rau AMS5812_0050-D-B 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:

Tus lej Arduino rau AMS5812_0050-D-B tuaj yeem rub tawm los ntawm peb GitHub chaw cia khoom-Dcube Store.

Nov yog qhov txuas rau tib yam:

github.com/DcubeTechVentures/AMS5812-0050-D-B

Peb suav nrog tsev qiv ntawv Wire.h los pab txhawb I2c kev sib txuas lus ntawm lub sensor nrog Arduino board.

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.

// Thov 4 bytes ntawm cov ntaub ntawv

Wire.requestFrom (Addr, 4);

// Nyeem 4 bytes ntawm cov ntaub ntawv

yog (Wire.available () == 4)

{

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

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

cov ntaub ntawv [2] = Wire.read ();

cov ntaub ntawv [3] = Wire.read ();

}

// Hloov cov ntaub ntawv

ntab siab = ((cov ntaub ntawv [0] & 0xFF) * 256 + (cov ntaub ntawv [1] & 0xFF));

ntab temp = ((data [2] & 0xFF) * 256 + (data [3] & 0xFF));

siab = ((siab - 3277.0) / ((26214.0) / 10.0)) - 5.0;

ntab cTemp = ((temp - 3277.0) / ((26214.0) / 110.0)) - 25.0;

ntab fTemp = (cTemp * 1.8) + 32;

// Cov ntaub ntawv tso tawm rau tus saib xyuas

Serial.print ("Siab:");

Serial.print (siab);

Serial.println ("PSI");

Serial.print ("Kub hauv Celsius:");

Serial.print (cTemp);

Serial.println ("C");

Serial.print ("Kub hauv Fahrenheit:");

Serial.print (fTemp);

Serial.println ("F");

ncua (500);

}

Kauj Ruam 4: Cov ntawv thov:

AMS5812 yog lub zog ntsuas qhov ntsuas siab thiab nws tuaj yeem ua haujlwm hauv cov kab ke uas ntsuas qhov ntsuas zoo li qub thiab muaj zog thiab ntsuas ntsuas ntsuas siab. Nws ua lub luag haujlwm tseem ceeb hauv kev saib xyuas lub tshuab nqus tsev, Kev ntsuas roj ntws, ntsuas ntsuas dej nrog rau kev ntsuas kev kho mob.
