Product Description

HEC365 Cost-Effective 3D Electronic Compass RS232/RS485/TTL Output Optional Mechanical Control




Hec365 integrates a three-axis magnetic sensor. When calculating the heading in real time through the CPU, the three-axis accelerometer is used to compensate the inclination angle, so that it can provide accurate heading data in extremely harsh environment. Support RS232, RS485 and TTL level output interface. The output baud rate is 2400-115200 and the output angle is 0 ° ~ 360 °. There are two types: hexadecimal and Modbus protocol. It can meet the needs of different application scenarios, and can easily and quickly integrate the functions of electronic compass into various systems.
