Ntiaj Teb Cov Roj Teeb Yooj Yim Yooj Yim Txog 5v hauv MAh: 3 Cov Kauj Ruam

Arduino thiab tus tiv thaiv yog txhua yam peb xav tau los tsim cov qauv no uas tsim lub peev xwm ntsuas rau cov roj teeb hluav taws xob txog li 5v. Acid, alkaline, NiCd, Li-ions thiab Lipo roj teeb tuaj yeem siv tau. Kev ua lag luam puv ntawm cov roj teeb cuav thov muaj peev xwm loj tab sis xa ib feem ntawm qhov kev cog lus, nkees ntawm qhov xwm txheej no txoj haujlwm no pab tshawb pom qhov peev xwm tiag tiag ntawm cov roj teeb uas muaj thaum qee tus suav 8800 Li-ions tsis muaj 650mAh qhov tseeb.

Nws yog qhov tsim nyog yuav tsum tau ceev faj thiab tiv thaiv ntawm kev tso tawm, cov roj teeb rov qab yuav tsum tsis txhob tso tawm ntau tshaj 20% ntawm nws qhov hluav taws xob nominal, qhov no tuaj yeem ua rau puas tsuaj rau koj lub tsev.

Kauj Ruam 1: Muab Txhua Qhov Ua Ke Hauv Ib Qho Yooj Yim

Cov lus qhia tiv thaiv yog 22R / 10W lossis 10R / 10W, peb siv tom kawg vim tias nws nthuav qhia sijhawm tsawg dua. Txhawm rau ntsuas cov roj teeb me me zoo li CR2032 47R / 2W resistor tuaj yeem siv nrog kev tso tawm qeeb, zam kev ua kom sov roj teeb.

Rau qhov raug, tsuas yog ob qho kev hloov kho yuav tsum tau ua hauv txoj cai. Qhov sib txawv "vcc" yuav tsum tau txais qhov ntsuas ncaj qha tus nqi ntawm Arduino board. Qhov sib txawv "resistor" yuav tsum tau txais tus nqi tseeb ntawm tus tiv thaiv hauv Ohms thiab cov lej zauv tuaj yeem siv tau.

Hauv txoj hauv kev yooj yim Serial Monitor los ntawm Arduino IDE tau siv los ua qhov cuam tshuam, qhia qhov tseem ceeb nyeem txhua 1.8s, yog li PC yuav tsum txuas nrog rau arduino thaum qhov kev xeem tau ua tiav, lub qhov rai tuaj yeem txo qis tso cai siv computer rau lwm tus. lub hom phiaj, txawm li ntawd los tus qauv tsim tuaj yeem hloov kho tau yooj yim kom lees txais 16x2 LCD lossis 4-digit 7-segment display.

Lub sijhawm ntawm 1.8s tau raug xaiv vim nws tso cai hloov kho sai thiab vim tias nws yog ntau ntawm 60, sawv cev rau 0.0005 ntawm teev, uas ua kom yooj yim rau kev suav.

Ntxiv rau qhov ua qhov yooj yim tshaj plaws qhov kev daws teeb meem no kuj yog qhov pheej yig tshaj ntawm lwm tus uas tau tshawb fawb.

Kauj ruam 2: Txoj Cai

ntab vcc = 5.0; // Tus nqi hluav taws xob tiag ntawm arduino board - ntsuas nrog multimeterfloat soma = 0.0;

int analogInput = 0;

ntab vout = 0.0;

int tus nqi = 0;

ntab resistor = 10; // Tus nqi tseeb ntawm resistor hauv ohms, ntsuas nrog multimeter -

// siv hauv kev tsim: 10 Ohms / 10 Watts

void teeb tsa () {

Serial.begin (9600);

pinMode (analog nkag, INPUT);

Serial.println ("Nyeem txhua 1.8s");

ncua (1800);

}

void voj () {

tus nqi = analogRead (analogInput);

vout = (tus nqi * vcc) / 1024.0;

ntab cout = vout / resistor;

float parcial = cout * 0.0005;

soma = soma + haiv neeg;

Serial.print ("Tam sim no nyeem:");

Serial.print (cout);

Serial.print ("Amp.");

Serial.print ("Ntsuas kom deb li deb:");

ntab msoma = soma * 1000;

Serial.print (msoma);

Serial.println ("mAh");

// tos ntau 1.8 seg

ncua (1800);
