This is a breakout board featuring the fully integrated Hall Effect-based linear ACS758 current sensor. It offers accurate current measurement for both AC and DC signals. The thick copper conductor ensures the device can withstand high overcurrent situations. The ACS758 outputs an analog voltage signal that changes linearly with the sensed current. This sensor allows you to monitor currents in your project every second for energy-saving or circuit protection. It's great at measuring large currents easily. Features include Arduino interface compatibility, a 120 kHz typical bandwidth, a 3 µs output rise time in response to step input current, output voltage proportional to AC or DC currents, factory trimming for accuracy, extremely stable output offset voltage, nearly zero magnetic hysteresis, total output error improvement through gain and offset trim over temperature, a monolithic Hall IC for high reliability, and ultra-low power loss with a 100 µΩ internal conductor resistance. Specifications are as follows: Operating Voltage (analog) is 3.3 - 5V, Peak Measuring Voltage is 3000V (AC) and 500V (DC), Current Measuring Range is -50 - 50A, Sensitivity is 40 mV/A, Operating Temperature is -40 - 150°C, and Dimension is 34x34mm (1.34x1.34'). Documents available are Wiki (50A Current Sensor), sample code, ACS758 datasheet, and schematic. The shipping list includes 1 sensor and 1 Analog Sensor Cable (SKU:FIT0031).
Using this current sensor is quite simple. First, connect it to your project according to the schematic provided. Make sure the operating voltage you use is within the 3.3 - 5V range. Then, you can start monitoring the current in your project every second for energy - saving or protecting your circuit. When handling the sensor, avoid exposing it to over - current conditions beyond its specified range of - 50 to 50A. Also, keep the operating temperature between - 40 and 150°C. For maintenance, just keep it clean and dry. If you want to get more detailed information, refer to the Wiki and the ACS758 datasheet. You can also use the sample code as a reference for programming.
