What is Arduino®
Arduino® is an open-source prototyping platform based on easy-to-use hardware
and software. Arduino® boards are able to read inputs – light-on sensor, a
finger on a button or a Twitter message – and turn it into an output –
activating of a motor, turning on an LED, publishing something online. You can
tell your board what to do by sending a set of instructions to the
microcontroller on the board. To do so, you use the Arduino programming
language (based on Wiring) and the Arduino® software IDE (based on
Processing). Additional shields/modules/components are required for reading a
twitter message or publishing online. Surf to
www.arduino.cc for more information
Product overview
This module measures AC currents of up to 5 A in a contactless method! It has a simple analog voltage signal as an output interface and has a current to voltage conversion factor of 0,4 V / A. Its working frequency range is 20 Hz to 20 kHz and it has a dielectric strength of 600 V AC / 1min. That’s some power for a small sensor like this!
