Availability date:
1. Current sensor chip: ACS712ELC-30 A
2, pin 5 V power supply, on-board power indicator
3, the module can measure positive and negative 30 amp current, corresponding to the analog output 66 mV / A
4. When no detection current is passed, the output voltage is VCC/2
5. PCB board size: 31 (mm) x 13 (mm)
Note: ACS712 is based on the principle of Hall detection, please try to avoid the influence of the magnetic field when using!

Da prietene stiu ca este bidirectional, dar Vout al modululi este Vin/2, recte 5V tensiunea de referinta Arduino/2 care reprezinta 2.5V sau tensiune de offset. Cum ADC-ul Arduino are tensiunea de offset sau de pornire, ideala 0V, pentru a converti tensiunea in valori numerice, este normal ca tensiunea Vout de 2.5V a senzorului sa reprezinte un nou offset. Am testat senzorul pe semnal AC, iar daca-l pui pe osciloscop si iti configurezi placa de achizitie de date ADC ai sa intelegi ce vorbesc eu aici.
@Viorel A
Acel 2.5 V nu este un offset, este faptul ca este un senzor bidirectional. Cand curentul are sens contrar voltajul de iesire scade pana la 0 in functie de cat curent ai prin circuit

Un senzor de curent foarte precis de la allegro si destul de ieftin care are si offset la 2.5V pentru Arduino.
