The Hall Effect Bricklet extends Bricks and can magnetic flux density (magnetic induction) from -7mT to 7mT (milli Tesla). It can count the (dis-)appearances of magnetic fields and can for example be used to measure the speed of a wheel with attached magnet with a frequency of up to 10kHz.
The low/high threshold for the counter as well as a debounce time can be configured and adjusted to a specific application.
Example applications are:
- Detect if a door is open or closed
- Reading out water/electricity meters
- Counting RPM of motors
The Hall Effect Bricklet 2.0 has a 7 pole Bricklet connector and is connected to a Brick with a 7p-10p Bricklet cable.
