20A Range Current Sensor Module ACS-712 ACS712 20A Hall Effect Current Sensor Module Straight 3 Pin Range 20A Current Sensor Module For Arduino Uno R3 Raspberry Pi
This current sensor board is based on the Allegro ACS712ELCTR-20A bi-directional hall-effect current sensor chip that detects positive and negative flowing currents in the range of minus 20 Amps to positive 20 Amps. The board operates at 5V DC and the current flow through the sensor is converted to an output voltage starting at 1/2Vcc (or 2.5V) for no current flow and moves up 66mV per amp for positive current or down -66mV per amp for negative current.
For Example:
- The output voltage at +2 amps would be (2.5V + (0.066 * 2)) = 2.632 V
- The output voltage at -5 amps would be (2.5V – (0.066 * 5)) = 2.170
Specifications:
- Supply Voltage: 4.5V~5.5V DC
- Measure Current Range: -20A~ 20A
- Sensitivity: 66mV/A
- The current sensor chips: ACS712ELC
- Current Range: 20A
- Pin 5V power supply, on-board power indicator;
- The module can measure the positive and negative 30 amps, corresponding to the analog output 66mV / A;
- No test current through the output voltage is VCC / 2;
- PCB board size: 31x13mm
Note: ACS712 is based on Hall detection principle, please try to avoid the magnetic field, when using as it may impact the reading accuracy.
