Inertial Aerosystems is introducing a new low-cost digital compass module manufactured by USA-based Honeywell. Designated the HMR 3400, this innovative device is a three-axis, tilt-compensated electronic compass with low power consumption. It incorporates Honeywell's established magnetoresistive sensor technology coupled with a MEMS accelerometer to give a compact reliable tilt-compensated compass that provides compass headings as well as pitch and roll angles.
Included are provisions for hard and soft iron correction algorithms to handle magnetic distortion effects. The HMR 3400 has less than 1degree nominal heading accuracy with 0.1 degree resolution and an update rate of up to 8Hz, with +/-60 degrees pitch and roll measurement. The operating temperature is -40 to 85degC and the module requires only 5V DC. The compass comes with a UART serial data interface and the 'industry-standard' Honeywell compass instruction set.
Suitable for use where space and weight are at a premium, it measures 15.24mm x 25.43mm and weighs 3.75g. Designed for high-volume OEM applications, the HMR3400 is available in tape-and-reel packaging.
This versatile product can be used for measuring tilt/movement of machinery, robotics, unmanned vehicles, vessels and buildings, as well as for applications in navigation, dead reckoning, personal and onboard navigation.
