About this product
A linear Hall-effect current sensor module that measures current through a conductor with galvanic isolation between the power path and the output. Its internal conductor resistance is 100 μΩ, and an integrated shield reduces noise in high-side, high-voltage sensing. It suits monitoring current in motors, batteries and power supplies.

Frequently asked questions
How is it connected in a circuit?
The current path goes through the module's conductor terminals in series with the load, and the sensor output is read as a voltage. Confirm the sensitivity and supply voltage on the module's documentation.
Can I read it with a microcontroller?
Yes, the output is an analog voltage that can go to an ADC input. Make sure the output swing matches your microcontroller's ADC reference voltage.
