HCM360 is a high-precision all-attitude three-dimensional electronic compass. It uses hard iron and soft iron calibration algorithms, allowing it to provide high-precision heading information within a 360° roll and +/-90° pitch range. It features a small size and low power consumption, making it more suitable for measurement systems sensitive to power and volume.
The precise attitude of the product output carrier can be used in systems with full attitude rotation. This product includes hard magnetic, soft magnetic, and tilt compensation, providing high-precision measurement values after compass output calibration. It integrates three-axis fluxgate technology, calculating heading in real-time through a central processor, and uses a three-axis accelerometer for heading compensation based on tilt angle, ensuring accurate heading data even in extremely harsh environments. Its small size and low power consumption make it widely used in various fields such as oil logging, antenna pointing, vehicle navigation, and attitude systems.
Main Features
● Measurement range 0~360° all attitude ● Heading accuracy 0.3~0.5°, resolution 0.1° ● Output frequency 5~100HZ optional ● Input voltage DC 5V
● Wide temperature operation -40 to +85℃ ● Includes hard magnetic, soft magnetic, and tilt compensation ● Baud rate 2400~115200 adjustable ● Operating current 40mA
● IP67 protection level ● Output RS232/RS485/TTL/MODBUS/CAN (optional) ● Small size (72*16*12mm) (customizable)
Product Applications
● Individual combat equipment ● Satellite solar antenna positioning ● AGV carts ● Mining machinery, oil logging equipment ● Medical equipment
● Gimbal leveling ● Drone positioning and navigation ● Based on tilt monitoring ● Angle control for various engineering machinery ● Bridge dam monitoring
