Overview
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.
Das Hall Current 3 Click Board™ ist ein sehr genaues Click Board™ zur Strommessung, das den Hall-Effekt nutzt, um eine präzise und zuverlässige Messung von relativ hohen Strömen zu ermöglichen. Sein auffälligstes Merkmal ist ein sehr niedriger Serienwiderstand von nur 0,7 mOhm, was dieses Gerät zu einem nahezu perfekten Amperemeter macht. Der maximale Strom, der vom integrierten Hall-Sensor-IC MLX91210 gemessen werden kann, beträgt bis zu ±30 A, aber in Bezug auf die Nennstrommessung des Sensors ist die Strommessung auf etwa ±10 A begrenzt.
Die Messung wird thermisch kompensiert und durch die integrierten analogen Hochgeschwindigkeits-Frontend-Abschnitte des Hall-Sensor-ICs aufbereitet. Der aktuelle Messwert kann über die I2C-Schnittstelle vom integrierten 12-Bit-A/D-Wandler bezogen werden.
