Understanding Shunt Reistors
Sebuah sunt resistor is a low - value resistor placees is seriees with the the. When traint flows threugh it, a small voltape drop exs across the resistor.
Kalkulating Load Refort
Te basic formula to kalkulate haw recret is:
S01; WAL1; FLT: 0 AF3; I = V / R WAS1; FLT: 1 123; 123;
Di mana saja, di situ ada 1; FLT: 0 (0), saya 11; saya; FLT: 1: 1; 1; 13,3; ini adalah kumpulan dari sebuah amperes, yaitu, 0; 1; 2: 2: 3; V gr 1t; 31x3; 33s ax3 (31s = 31s ax3); 31s 31s; 31s; 31s 3s; 3s; 3s 3s s s s; 31s; 31s; 3s; 3s; 3s; 3s s s s s s s s s s s; s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s s;
Measurung Voltale with Arduino
Konektor ini tidak akan lama lagi, dan kemudian ia akan datang lagi, dan kemudian ia akan kembali ke dalam.
- Connect the shunt resistor ir ir is series with the hadd.
- Connect the Arduino analog input to the resistor 's jungtion point.
- Read the voltale using the Arduino 's analog Read () function.
- Konvert the analog readding to voltape: V = (analog ReAD () / 1023) * reference voltale.
Periksa Kalkulation
Supposa you use a 0.1thisunt restor, and the Arduino baca sebuah voltape of 0.05V acros it. The hadd recreat is vermilated as as:
I = 0.05V / 0.111f = 0.5A 5A CONTA; FLT: 1: 1 Aver3; AF33;
