ACS758 100A Hall Effect Current Sensor

Description

The HW-525 module is built around the ACS758 hall-effect IC, giving you an analog output proportional to current flow through its onboard conductor path, rated up to 100A. It’s a common choice for battery monitoring, motor current sensing, overcurrent protection circuits, and power meters where you need to measure current without breaking the circuit or adding an inline shunt resistor. Simple 3-pin output (VCC, GND, analog signal) makes it easy to read directly with an Arduino or any microcontroller’s ADC.
