Description

Brief Introduction:

  • As an improvement version of DC-SS503, this magnetic sensor module provides an easy-to-use yet more convenient PIC16F690-based UART interface for system integration requirements while I 2 c is still reserved. With the help of powerful dual-axis magnetic sensor IC MMC2120MG, the ouput range can be as wide as 0°-359°. The geomagnetic calibration algorithm helps keep the interference of other magnets to the minimum and in the mean time, allows users to set declination. The DIP-like packaging of this module facilitates not only the further development but also the system integration.
