DESCRIPTION

· The HMR3200/HMR3300 are digital compass solutions by Honeywell for precision heading applications.

· Utilizes magnetoresistive sensors for reliability and accuracy in compact, solid-state designs.

· Features a 5-voltage logic level serial data interface with ASCII format commands.

· HMR3200 is a two-axis compass with three orthogonal sensors, suitable for vertical or horizontal use.

· HMR3300 includes a MEMS accelerometer for tilt compensation, effective up to ±60° tilt.

FEATURES

· Compact design on a 1.0” by 1.5” PCB, facilitating integration into daughter/motherboards.

· High precision with ±1° accuracy at level heading and ±0.1° resolution.

· Tilt compensation in HMR3300 using MEMS accelerometer for up to ±60° pitch and roll.

· Consistent performance with magnetoresistive sensor technology and 8 Hz update rate.

· Includes hard-iron compensation and user-driven calibration for stray field nulling.

· Operates in a wide temperature range from -40° to +85°C, suitable for various environments.

· Supports UART and SPI communication with an intuitive command language.

APPLICATIONS

· Ideal for integration into consumer and industrial systems requiring precise heading data.

· Suitable for control system applications needing rapid heading computations.

· Comes with a demonstration kit including RS-232 motherboard PCB, cable, 9-volt power supply, PC demo software, and a carrying case.
