WCS1800 35A Hall-Effect Linear Current Sensor Module

WCS1800 35A Hall-Effect Linear Current Sensor Module

The WCS1800 35A Hall-Effect Linear Current Sensor Module is a Hall-effect-based current measurement board designed to monitor high-current AC and DC lines and detect instances where the current exceeds a preset level.

The module features a WCS1800 Hall-effect current sensor, a comparator circuit, and an adjustment potentiometer. This allows not only for analog current measurement but also for generating a digital warning signal if the current exceeds the defined threshold.

The board's analog output produces a voltage proportional to the measured current, which can be read via a microcontroller's ADC input. The digital output generates a signal when the current exceeds the threshold set by the onboard trimmer potentiometer.

This feature facilitates the implementation of motor stall detection, over-current warning, and short-circuit detection systems.
