Arduino 20A Current Sensor Module - Blue (new Improved terminal)

Color: Blue

Material: PCB + metal
ACS712ELCTR-20A sensor chipset

Output 100mv per A 100mv/A
Powered by 5V power supply
Measures -20~+20A current, corresponding simulation output 100mV/A
Output voltage is VCC/2 when on current was measured
ACS712 is based on the principle of Hall detection, please avoid the magnetic field affect when using it

Code Example for Arduino

Measuring Current Using ACS712
*/
const int analogIn = A0;
int mVperAmp = 185; // use 185 for 5A Module, 100 for 20A Module and 66 for 30A Module
int RawValue= 0;
int ACSoffset = 2500; 
double Voltage = 0;
double Amps = 0;

void setup(){ 
 Serial.begin(9600);
}

void loop(){
 
 RawValue = analogRead(analogIn);
 Voltage = (RawValue / 1023.0) * 5000; // Gets you mV
 Amps = ((Voltage - ACSoffset) / mVperAmp);
 
 
 Serial.print("Raw Value = " ); // shows pre-scaled value 
 Serial.print(RawValue); 
 Serial.print("\t mV = "); // shows the voltage measured 
 Serial.print(Voltage,3); // the '3' after voltage allows you to display 3 digits after decimal point
 Serial.print("\t Amps = "); // shows the voltage measured 
 Serial.println(Amps,3); // the '3' after voltage allows you to display 3 digits after decimal point
 delay(2500);
