Sens­ing and con­trol­ling cur­rent flow is a fun­da­men­tal require­ment in a wide vari­ety of appli­ca­tions includ­ing, over-cur­rent pro­tec­tion cir­cuits, bat­tery charg­ers, switch­ing mode pow­er sup­plies, dig­i­tal watt meters, pro­gram­ma­ble cur­rent sources, etc. This ACS721 cur­rent mod­ule is based on ACS712 sen­sor, which can accu­rate­ly detect AC or DC cur­rent. The max­i­mum AC or DC that can be detect­ed can reach 20A, and the present cur­rent sig­nal can be read via ana­log I / O port of Arduino.SpecificationSup­ply Volt­age: 4.5V~5.5V DCMea­sure Cur­rent Range: ‑20A~ 20ASen­si­tiv­i­ty: 180mV/A ~190mV/A, Typ­i­cal: 185mV/AExternal Link & DownloadACS712 DatasheetACS712 Arduino Pro­gramUse­ful Introduction_1 from embed­ded-lab.Use­ful Introduction_2 from embed­ded-lab.Wiki link
