Introduction

When you want to measure AC current it is impractical and hazardous to cut in to your live wiring.

The analog AC current sensor developed by DFRobot is a good solution to this problem. Using

induction you can measure AC current without intrusive methods. Place your AC wire inside the unit,

connect the unit to the sensor board using the 3.5mm jack connector and connect the sensor board

to an analog input on your microcontroller. Use this sensor to measure AC motors, lighting

equipment, air compressors or any other devices that use AC current.
