Gravity Analog AC Current Sensor with Current Clamp

If you want to measure alternating current, it's often impractical and dangerous because you have to interrupt the line. The analog alternating current sensor developed by DFRobot is a good solution for this problem. With the included current clamp, you do not need to interrupt the line. The measured current is converted into an analog signal that you can then evaluate on an Arduino.

Info: You can reverse the polarity of the connection cable by attaching a Dupont cable M-M 10cm to male, so you can also use it on an Arduino UNO.
