Si7210 Hall Effect Magnetic Sensor
Si7210 sensors allow you to control and configure the device and read the magnetic field data over I2C on demand. With configurable digital output that allows the host to be interrupted when specified events happen, Si7210 sensors are ideal replacements for switch/latch and linear output magnetic sensors.

Si72xx-EVAL-KIT Magnetic Sensor Evaluation Kit
The SI72xx-EVAL-KIT showcases the different types of sensors within the Si72xx family. The quick connect USB dongles allows the small “postage stamp” boards to be connected to a PC host and evaluated. Once connected a graphical user interface tool can show the user the output of the magnetic sensor, a small magnet is provided in the kit to easily alter the output of the sensor.
