Si7210 霍尔效应磁性传感器

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.

电流消耗
As low as 400 nA @ 5 Hz
Max magnetic field
200 mT
