Original WCS1500 Hall Effect based Current Sensor (0-200A)
WCS1500 Hall Effect Current Sensor
Overview
Non-invasive current sensor (no wire cutting required)
Based on Hall Effect principle
Measures both AC and DC current
Suitable for high-current applications (up to 200A)
Compatible with Arduino, ESP32, Raspberry Pi
Working Principle
Current-carrying wire passes through built-in hole (9mm)
Current generates a magnetic field
Internal Hall sensor detects magnetic field
Converts it into proportional analog voltage output
No direct electrical contact with measured circuit
