When you want to measure AC current, you still have trouble cutting wires, wires, or soldering. Gravity: An analog AC sensor comes to the rescue, eliminating the need to cut wires or reconnect circuits. Simply install the AC adapter probe on the AC power line, then plug the 3.5mm headphone jack into the signal conversion module to read the current AC value. The analog output is designed to be compatible with the 3V3 / 5V micro-controller. It can be easily used to measure AC current to monitor AC motors, lighting equipment, air compressors, etc.
