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
Jargon buster
Plain-language definitions for the technical terms used above.
- GND
- GND is the ground or reference connection (0 V) for a circuit. When connecting two devices together, their grounds must be joined so both agree on what counts as a low or high signal.
- VCC
- VCC is the positive power-supply connection on a chip or module. Connecting it to the correct supply voltage is needed for the part to power on and helps avoid damaging the electronics.
