## Description

The Octopus TA12-100 is a non-invasive AC current sensor brick from ElecFreaks. It uses a current transformer to measure AC current flowing through a wire without needing to cut or splice the circuit — simply clamp it around the conductor. The sensor outputs an analogue voltage proportional to the detected current. Part of the Octopus electronic brick series, it features a standard 3-pin interface for plug-and-play connection to Arduino boards via sensor shields. Key Features Non-Invasive Measurement – Clamp-on design measures AC current without breaking the circuit Wide Detection Range – Suitable for a variety of AC current sensing applications Fast Response – High sensitivity with stable, long-life operation Simple Interface – 3-pin analogue output (Signal, VCC, GND) for easy integration Octopus Brick Format – Compatible with Arduino sensor shields and Freaduino boards Specifications Operating Voltage – 5 V Interface Type – Analogue Pin Definition – 1: Signal, 2: VCC, 3: GND Sensor Type – Current transformer (TA12-100) Ideal For AC current monitoring and energy metering projects Arduino-based power measurement systems Home automation current sensing Educational electronics projects
