Want to measure Hall Effect? We have the Grove – Hall Sensor v1.0 for it. It’s a Grove compatible and continuous-time hall sensor by Seeed Studio especially made to measure Hall Effect. The Hall Effect is a production of a voltage difference across an electrical conductor, transverse to an electric current in the conductor as well as a magnetic field perpendicular to the current. The output of the continuous-time switch Hall Sensor on this Twig switches low and turns on when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high and turns on when the magnetic field disappears.

The output of the continuous-time switch Hall sensor on this Twig switches low and turns on when a magnetic field (south polarity) perpendicular to the Hall sensor exceeds the BOP threshold, and it switches high and turns on when the magnetic field disappears. This sensor has a 400ns transition period for rise and fall as well as reverse battery protection. It is easy to use and compatible with the Grove interface. You can use it for RPM meter and Simple DC motor.

For all Grove users (especially beginners), Seeed Studio provides guidance PDF documents. Please download and read through Preface – Getting Started and Introduction to Grove before your using of the product. This is a suitable product for not only Grove users but also all electronic enthusiasts. So buy it now!
