Lub ntsuas siab tau siv los ntsuas cov dej hauv lub tank.

Khoom siv:

24PC sensor

Ib daim ntawv qhia zaub mov

Resistors

Amplifiers

Tank

Kauj Ruam 1: 24PC Siab Sensor

24PC Series Miniature Pressure Sensors yog qhov me me, cov khoom siv tau zoo npaj rau siv nrog ntub lossis qhuav tawm.

Cov cuab yeej no muaj cov cuab yeej siv pov thawj pom tseeb uas siv cov khoom tshwj xeeb piezoresistive micromachined sensing element los muab kev ua haujlwm siab, ntseeg tau, thiab raug. Txhua lub ntsuas hluav taws xob muaj plaub tus ua haujlwm piezoresistors uas tsim ua tus choj Wheatstone. Thaum siv qhov siab, qhov tsis kam hloov pauv thiab lub ntsuas hluav taws xob muab lub teeb liab milliVolt uas yog qhov sib piv rau qhov siab nkag.

Kauj ruam 2: Tsim Circuit Court

24PC lub ntsuas hluav taws xob txuas nrog lub choj Wheatstone Choj hauv lub Tank.

Qhov Sib Txawv Sib Txawv Sib Txuas tau txuas nrog cov tswv yim tawm tsam ntawm 270 K ohms thiab cov khoom tawm ntawm 1 M ohms, kom muab qhov nce ntawm 3.7.

Lub tshuab hluav taws xob uas tsis hloov pauv tau txuas nrog lub zog ntawm qhov sib txawv ntawm lub tshuab hluav taws xob nrog cov lus tawm tsam ntawm 1 k ohms thiab cov khoom tawm ntawm 165 K ohms. Tsis pom tus tiv thaiv nrog tus nqi ntawd yog li 220 K ohms resistor tau siv los muab qhov nce ntawm 166.

Tag nrho cov txiaj ntsig tau los ntawm cov tshuab hluav taws xob yog 610.

Hloov chaw ntawm qhov sib txawv thiab tsis hloov pauv lub zog, ib qho khoom siv hluav taws xob tau tsim nrog ib tus tiv thaiv ib leeg nrog tus nqi ntawm 330 ohms kom muab qhov nce ntawm 610.

Kauj Ruam 3: Ntsuas Qhov Hluav Taws Xob Tawm Los Ntawm Lub Tank

Qhov hluav taws xob tso tawm yog ntsuas los ntawm Tank los ntawm kev ntsuas qhov ntsuas hluav taws xob ntawm txhua qib ntawm cov dej kom txog rau sab saud. Qhov siab tshaj plaws yog 8.2 mV thaum lub Tank puv.

Daim duab thib ob qhia txog kev sib raug zoo ntawm cov khoom tso tawm los ntawm lub tank thiab cov zis los ntawm lub tshuab raj ntawm qib sib txawv ntawm cov dej. Txoj kab nqes qhia qhov nce.

Kauj ruam 4: Teeb meem Shooting

Lub Circuit Court tau txuas nrog txoj hauv kev tab sis qhov hluav taws xob tso tawm los ntawm lub tshuab hluav taws xob tsis hloov pauv thaum ntxiv dej rau hauv lub tank.

Qhov sib txawv thiab tsis hloov pauv lub zog tau hloov los ntawm ib qho khoom siv ntsuas lub zog tab sis cov hluav taws xob tso tawm los ntawm lub tshuab hluav taws xob tseem tsis tau hloov pauv.

Cov resistors thiab amplifiers tau hloov nrog cov tshiab yog tias lawv puas tab sis qhov tshwm sim yog tib yam.

Kauj ruam 5: Arduino Code

Txoj cai no nyeem tus nqi tso tawm los ntawm lub tshuab hluav taws xob hauv cov chav digital.

{void teeb tsa ()

{Serial.begin (9600); // pib qhov txuas txuas nrog lub computerpinMode (A0, INPUT); // cov zis los ntawm lub tshuab raj yuav txuas nrog tus pin no

}

void voj () {

int AnalogValue = analogRead (A0); // Nyeem cov tswv yim ntawm A0

Serial.print ("Tus nqi sib piv:");

Serial.println (AnalogValue); // luam tawm tus nqi nkag

ncua (1000);

}
