Working Principle of Hall Effect Current Sensor
Hall Effect current sensors work by detecting the magnetic field generated by current flow using the Hall Effect principle. This allows the measurement of AC and DC currents without direct electrical contact, making them ideal for isolated and safe measurement.
Hall Effect DC vs AC Current Measurement
Hall Effect sensors are capable of both DC current measurement and AC current sensing, unlike current transformers that are limited to AC only.
- DC Current: Stable measurement using linear Hall sensors (e.g., ACS712 Hall Effect DC Current Sensor).
- AC Current: Accurate waveform tracking using closed-loop Hall Effect current sensors.
Types of Hall Effect Current Sensors
Common types of Hall Effect current sensors include:
- Open Loop Hall Effect Current Sensor
- Closed Loop Hall Effect Current Sensor
- Integrated Hall Effect Current Sensor Modules (e.g., ACS712 Module)
- IC based Hall Effect Current Sensor
- High Current Hall Effect Sensor (100A, 200A models)
Applications of Hall Effect Current Sensors
They are widely used in:
- Battery Management Systems (BMS)
- Electric Vehicles (EV) and Motor Control
- Solar Power Monitoring
- DIY Current Sensor Projects with Arduino
- Industrial Automation and Process Control
- Smart Energy Meters

FAQ about Hall Effect Current Sensors
- Does a Hall Effect Sensor generate its own current?
No, it requires a supply voltage and detects external magnetic fields caused by current flow. - How accurate are Hall Effect current sensors?
Closed loop sensors provide superior accuracy. Open loop types are more cost-effective but less precise. - What is the working principle of Hall Effect current sensor?
They measure the magnetic field perpendicular to current flow and convert it into voltage. - Can Hall Effect sensors be used for both AC and DC current measurement?
Yes, they are ideal for AC and DC current sensing.
