Factory price 3D electronic compass sensor adopts high-precision magnetometer technology and is widely used in fields such as drones, robots, navigation, and car navigation, providing stable and accurate attitude data.
Features
- 3D electronic compass sensor has hard magnetic, soft magnetic and tilt compensation, and the compass outputs calibrated high-precision measurement values.
- It uses the central processor to solve the heading in real time, and uses a three-axis accelerometer to compensate the tilt angle, so that it can provide accurate heading data even in extremely harsh environments.
- The compass sensor is precisely designed, the linearity is compensated again, and it integrates comprehensive protection functions such as short circuit, instantaneous high voltage polarity, surge, etc. The operating temperature reaches the industrial level of -40℃~85℃.

Tips: Precautions for installing 3D electronic compass sensors
Although the 3D electronic compass sensor can compensate for magnetic interference, in order to ensure the best measurement effect, users should choose an environment with minimal magnetic interference for installation and use. It is recommended to stay away from magnetic materials such as iron, nickel, magnets, and engines, and keep a distance of at least 0.5 meters. If there are these magnetic materials around, special attention should be paid. To ensure the best measurement effect of the product, non-magnetic screwdrivers and non-ferrous screws must be used during installation. In particular, strong magnetic materials such as magnets and motors should be kept at least 10 cm away from the compass to avoid affecting the measurement accuracy and causing irreversible errors.
