This is a breakout board for the fully integrated Hall Effect based linear ACS758 current sensor. The sensor gives precise current measurements for both AC and DC signals. The thickness of the copper conductor allows the survival of the device at high overcurrent conditions. The ACS758 outputs an analog voltage output signal that varies linearly with sensed current. This current sensor enables you to monitor currents in your project every second for energy saving or circuit-protecting purposes. Features Arduino interface compatible 120 kHz typical bandwidth 3 s output rise time in response to step input current Output voltage proportional to AC or DC currents Factory-trimmed for accuracy Extremely stable output offset voltage Nearly zero magnetic hysteresis Total output error improvement through gain and offset trim over temperature Monolithic Hall IC for high reliability Ultra-low power loss: 100 internal conductor resistance Specification Operating Voltage(analog): 3.3-5V Peak Measuring Voltage: 3000V(AC),500V(DC) Current Measuring Rang: -50~50A Sensitivity: 40 mV/A Operating Temperature: -40~150C Dimension: 34x34mm(1.34×1.34\”) Documents Wiki (50A Current Sensor) Sample code ACS758 datasheet Schematic Shipping List 1x Current Sensor 1xAnalog Sensor Cable
