Open-Smart ACS712 Current Sensor Module - 20A

A simple current sensor from Open-Smart that can measure both DC and AC current.

Specifications:

• Supply voltage: 4.5 - 5.5V DC
• Signal voltage: 0.5 - 4.5V
• Current sensor:
  • Measuring range: -20 - 20A
  • Accuracy: ±2%
  • Measuring method: Hall effect
  • Interface: Analog
  • Sensitivity: 100mV/A
  • Chip: ACS712ELCTR-20A-T
• Connector: Terminal block 2p M4
• Dimensions PCB: 42 x 24mm

When the measured current is zero, the output voltage is half the supply voltage.
