HEC303 3D High-Precision Electronic Compass Sensor
Introduction:
HEC303 is specially designed to improve the static measurement
accuracy of magnetic compass.It is composed of an industrial-grade
single-chip microcomputer with high reliability and strong
anti-interference ability, and a high-precision magnetic sensor and
drive chip. At the same time, it integrates the hard magnetic and
soft magnetic calibration algorithms of Bewis Sensing patented
technology, and uses a three-axis accelerometer to compensate the
tilt angle, so that accurate heading data can be provided in
extremely harsh environments.

FAQ
Q1: Accuracy definition of products
A: RMS accuracy, the accuracy of each product can be
traced.Accuracy test report can be provided if required.
Q2: How to select suitable model?
A: Users should check the following points:
a. Single or dual axis?
b. Commom protocol, Modbus or CAN?
c. Dynamic or static Application scenarios?
d. Horizontal or vertical installation?
Q3: How to purchase?
A: If you want sample, please purchase on BWSENSING online shop. We
accept Paypal/TT/CC.If you purchase in bulk, it is recommended to
consult the sales for the best price.
Q4: How long is the warranty period?
A: One year.
Q5: Precausions for using Electronic compass
A: Please refer to manual, and keep away from sensitive items like
iron or motors, or even your cell phone；Electronic compass outputs
magnetic north, not true north.
Q6: How to calibrate electronic compass?
A: a. Consult Sales about corresponding calibration videos.
b. It is divided into common calibration and 12 point calibration.
The 12-point calibration is only for high-precision electronic
compass.
c. Customized NMEA output.
