Kauj Ruam 3: Kev Ntsuas Hluav Taws Xob

Qhov ntsuas hluav taws xob tau ntsuas los ntawm kev pab ntawm qhov hluav taws xob faib hluav taws xob. Vim li ARDUINO analog pin input voltage raug txwv rau 5V Kuv tsim qhov faib hluav taws xob nyob rau hauv xws li ib txoj hauv kev uas qhov hluav taws xob tso tawm los ntawm nws yuav tsum tsawg dua 5V. Kuv lub roj teeb siv rau khaws cia lub zog los ntawm lub hnub ci vaj huam sib luag tau ntsuas 6v, 5.5Ah, yog li kuv yuav tsum nqis qis 6.5v rau qhov hluav taws xob qis dua 5V. Kuv siv R1 = 10k thiab R2 = 10K. Tus nqi R1 thiab R2 tuaj yeem qis dua ib qho tab sis qhov teeb meem yog tias thaum kev tiv thaiv qis dua tam sim no ntws los ntawm nws vim yog qhov ua rau muaj hwj chim loj (P = I^2R) tso tawm hauv cov cua sov. Yog li tus nqi sib txawv tuaj yeem xaiv tau tab sis kev saib xyuas yuav tsum tau ua kom txo qis lub zog poob hla qhov tsis kam. Vout = R2/(R1+R2)*Vbat Vbat = 6.5 thaum them tas R1 = 10k thiab R2 = 10k Vout = 10/(10+10)*6.5 = 3.25v uas qis dua 5v thiab haum rau ARDUINO analog pinNOTE Kuv tau qhia 9 Volt roj teeb hauv lub rooj sib tham tsis sib xws tsuas yog piv txwv los txuas xov tooj, tab sis lub roj teeb tiag kuv tau siv yog 6 Volt, 5.5Ah ua kua qaub roj teeb. Voltage Calibration: Thaum lub roj teeb tau them tag nrho (6.5v) peb yuav tau txais Vout = 3.25v thiab tus nqi qis dua rau lwm cov roj teeb qis. AEDUINO ADC hloov pauv Analog teeb liab mus rau qhov kwv yees kwv yees digital. Thaum lub roj teeb hluav taws xob yog 6.5v Kuv tau txais 3.25v los ntawm qhov faib hluav taws xob thiab piv txwv 1 = 696 hauv qhov ntsuas, qhov piv txwv 1 yog ADC tus nqi sib xws rau 3.25v Rau kev nkag siab zoo dua Kuv tau txuas lub sijhawm simulation los ntawm 123D.circuit rau ntsuas ntsuas ntsuas: 3.25v sib npaug rau 696 1 yog sib npaug rau 3.25/696 = 4.669mv Vout = (4.669*sample1)/1000 volt Lub roj teeb tiag tiag = (2*Vout) voltARDUINO CODE: // ntsuas 150 qhov ntsuas los ntawm kev faib hluav taws xob nrog rau ntu ntawm 2sec thiab tom qab ntawd nruab nrab qhov piv txwv cov ntaub ntawv khaws tseg rau (int i = 0; i <150; i ++) {sample1 = sample1+analogRead (A2); // nyeem qhov hluav taws xob los ntawm kev faib hluav taws xob ncua qeeb (2); } qauv 1 = qauv1/150; qhov hluav taws xob = 4.669*2*qauv 1/100;
