Note: The board comes with a Grove connection cable. You can purchase an additional Grove Base Shield to connect with Arduino or the Seeeduino Lotus (Arduino Uno Compatible), Grove Base Hat to connect with Raspberry Pi, or Grove Shield for XIAO to connect with the XIAO boards from Seeedstudio for programming and control.
The Grove - Hall Sensor (Hall Magnetic Field Sensor) is used to detect magnetic fields based on the Hall effect and is used in applications such as door opening/closing detection, motor speed measurement, etc. The sensor is very easy to use with high accuracy.
Technical specifications:
SKU: 101020046 Main IC: A1101 Operating voltage: 3.3~5VDC Supply Current: 4.1~24 mA Detects magnetic fields based on the Hall effect.
