Hall Current 3 Click Board

The Hall Current 3 Click Board™ is a very accurate current measurement Click Board™, which utilises the Hall effect to provide a precise and reliable measurement of reasonably high current. Its most distinctive feature is a very low series resistance of only 0.7mohm, making this device a nearly perfect ammeter. The maximum current which can be measured by the MLX91210 integrated Hall sensor IC goes up to �30A, but with respect to the nominal current measurement rating of the sensor, the current measurement is limited to about �10A. The measurement is thermally compensated and conditioned by the high-speed integrated analogue front-end sections of the Hall sensor IC. The current measurement value can be obtained from the onboard 12-bit A/D converter, via the I2C interface.
