2019-03-12What problems should I pay attention to when using the electronic compass?

1. Firstly, the sensor's power supply voltage is determined according to the label of the sensor, and the output mode is wired according to the corresponding interface mode, and the corresponding protocol is used;

2. Use a multimeter to check the power supply voltage to ensure that the power supply is normal;

3. Although the electronic compass can compensate for magnetic interference, the user should select an environment with minimal magnetic interference to install and use. Choose as far away as possible from iron, nickel, magnets, engines and other magnetic materials.

4. The product has been calibrated at the factory. In places where the influence of the magnetic field environment is small, it is not necessary to perform environmental calibration when using it, and it can be used directly. During actual use, it is recommended to perform calibration.
