HEC365 3-Axis 360 degree Digital Compass Module

Accuracy: 0.3 degree -0.5 degree Dip Angle: 360 degree RS232/RS485 Optional Small size: L113*18*18mm General DescriptionHEC365 is a high accuracy 3-Axis digital compass with 360°Dip angle compensation. Which uses advanced algorithms, with hard iron and soft iron corrections, to provide highly accurate heading information over its extra wide tilt range. The small size and low power requirements of the HEC365 allow it to fit into today’s size sensitive systems. These advantages make Witlink Corporation's HEC365 the choice for applications that require highest accuracy and performance anywhere in the world.Features include an extra wide tilt range, high accuracy compass heading, low powerconsumption, large signal noise immunity under all conditions, and a large magnetic field measurement range in a small package.The HEC365 combines USA patented Magneto-Inductive (MI) sensors and measurement circuit technology with a three-axis MEMS accelerometer for unparalleled cost effectiveness and performance. The magnetic sensors and accelerometers are calibrated to operate from -40 to 85°C; hence the measurement is very stable over temperature and inherently free from offset drift.HEC365 adopts high-tech levels such as MCU, Water-proof, dust prevention and anti-corrosion PCB, import cable,wide temperature metal-clad ,and so on, to improve the stability and reliability.FeaturesAccuracy: 0.3 °-0.5°                           Maximum Dip Angle: 360°RS232/RS485 Optional                        Small size: L113*18*18mmBinary RS232 interface                       Widely working temperature: -40°C~+85°CSmall form factorLow power consumptionHard and soft iron correction with quality of calibration scoreApplicationsHigh performance ROV navigation              GPS system integrationVehicle tracking                              Remote terrestrial antenna direction indicatorsSonar targeting systems                      3-axis magnetic field sensingSurvey equipment                            AutopilotSatellite positioning Search                    Robotic systems
