This module is ideally suited to providing an accurate current measurement in the region of -20 to +20 Amps. A proportional voltage signal will be provided on the OUT pin, centred around VCC/2 (typically 2.5V for a 5V supply). The module operates on a change in output of 100mV per Amp. This provides a simple and effective way of monitoring current in your project.
Please note that the chip on-board this module uses the hall effect to measure the current and as such is susceptible to magnetic interference.
