TSL45315 yog lub teeb pom kev zoo ib puag ncig digital. Nws kwv yees tib neeg qhov muag teb raws ntau yam teeb pom kev zoo. Cov cuab yeej muaj peb lub sijhawm xaiv ua ke thiab muab ncaj qha 16-ntsis lux tso tawm ntawm I2C tsheb npav sib cuam tshuam. Cov cuab yeej muaj cov kab ntawv photodiode, kev sib xyaw ua ke sib piv-rau-digital hloov pauv (ADC), teeb liab ua cov kab hluav taws xob, cov lej xav txog qhov xav tau, thiab I2C cov lej sib cuam tshuam ntawm ib qho CMOS kev sib txuas ua ke los muab cov ntaub ntawv lux. Nov yog nws qhov ua piv txwv nrog arduino nano.

Kauj Ruam 1: Yam Koj Xav Tau..

1. Arduino Nano

2. TSL45315

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 kawg ntawm I2C cable rau TSL45315 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 TSL45315 tuaj yeem rub tawm los ntawm peb GitHub chaw cia khoom-Dcube Store.

Nov yog qhov txuas rau tib yam:

github.com/DcubeTechVentures/TSL45315…

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.

// Cov cai no tau tsim los ua haujlwm nrog TSl45315_I2CS I2C Mini Module muaj los ntawm hauv Dcube Store.

{

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

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

}

// Hloov cov ntaub ntawv

ntab luminance = cov ntaub ntawv [1] * 256 + cov ntaub ntawv [0];

// Cov ntaub ntawv tso tawm rau Serial Monitor

Serial.print ("Ambient Light Luminance:");

Serial.print (luminance);

Serial.println ("lux");

ncua (300);

}

Kauj Ruam 4: Cov ntawv thov:

Qhov dav dav dav ntawm lub teeb pom kev ib puag ncig ua rau nws muaj txiaj ntsig tshwj xeeb hauv kev siv sab nraum zoov uas nws raug rau tshav ntuj ncaj qha. Cov cuab yeej siv tau zoo tshaj plaws rau kev siv tsis siv neeg kev teeb ntawm txoj kev thiab kev nyab xeeb, daim ntawv tshaj tawm, thiab teeb pom kev zoo hauv tsheb. TSL45315 cov cuab yeej kuj tseem tuaj yeem siv hauv lub xeev ruaj khov thiab teeb pom kev zoo rau kev tswj tsis siv neeg thiab kev sau hnub nruab hnub kom ua kom muaj kev txuag hluav taws xob ntau. Lwm daim ntawv thov suav nrog tso saib lub teeb pom kev zoo txhawm rau txuas lub roj teeb lub neej thiab ua kom pom kev zoo hauv xov tooj ntawm tes, ntsiav tshuaj, thiab phau ntawv sau.
