### [Octopus Non-invasive AC current sensor TA12-100 Brick](https://littlebirdelectronics.com.au/products/octopus-non-invasive-ac-current-sensor-ta12-100-brick.md)

**Brand:** ElecFreaks

**Price:** $12.55

**Stock:** Out of stock

**SKU:** EF-EF04015

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 th...
