Gravity: Analog AC Current Sensor

SKU: SEN0211

The Gravity Analog AC Current Sensor provides a non-invasive way to measure AC current without cutting, stripping, or rewiring cables. Simply clamp the open-type AC transformer probe around the AC line and connect the standard 3.5 mm plug to the signal conversion module to obtain real-time current readings. Designed for compatibility with both 3.3 V and 5 V microcontrollers, the module outputs a clean analog voltage corresponding to the measured AC current. This makes it ideal for monitoring AC motors, lighting equipment, household appliances, air compressors, and other AC loads in automation, energy management, and smart control applications.
