HMR 3400 provides low-power tilt measurement

An Inertial Aerosystems UK product story
Edited by the Engineeringtalk editorial team Apr 16, 2009

Inertial Aerosystems has introduced Honeywell's HMR 3400, a three-axis tilt-compensated electronic compass with low power consumption.

The HMR 3400 incorporates Honeywell's magnetorestive sensor technology, coupled with a MEMS accelerometer to give a compact and reliable tilt-compensated compass that provides compass headings and pitch and roll angles.

It includes provisions for hard and soft-iron correction algorithms to handle magnetic distortion effects.

The HMR 3400 has less than one-degree nominal heading accuracy with 0.1 degree resolution.

It has an update rate of up to 8Hz, with +/-60 degree pitch and roll.

The operating temperature is -40 to 85C and requires only 5V DC.

The compass comes with a UART serial data interface and the Honeywell compass instruction set.

It measures 15.24 x 25.43mm and weighs 3.75g.

The HMR3400 was designed for high-volume OEM applications.

It 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.
