Current Sensor ACS723 (AC or DC) 5A simple dc the output current limit canThe Allegro ACS723 provides economical and precise solutions for AC or DC current sensing in industrial, commercial, and communications systems. These are good sensors for metering and measuring overall power consumption of systems. The ACS712 current sensor measures up to 5A of DC or AC current. The ACS712 Low Current Sensor Breakout outputs an analog voltage that varies linearly with sensed current. To calibrate, first set the output offset to the
