How to Use Wind Direction Sensor with Arduino

admin November 18, 2021 analog sensor Arduino sensor wind direction sensor

We will learn how to use this analog wind direction sensor This is a Chinese wind direction sensor, sometimes it is just really hard to get the datasheet, or we can’t read the datasheet in Chinese. Let’s see the specification first, I don’t read Chinese but I think the label means operating voltage or voltage input is 12-24 volt. And the output is 0-5 volt.

How to use HMC5883L Compass Sensor

admin November 17, 2021 Arduino C++compass electronics HMC5883L honeywell I2C sensor magnetometer maker sensor tutorial

Three-axis means this sensor can detect movement on X, Y, Z-axis or usually we called that 3 axis magnetometer. So it’s not only the direction in the degree that we are able to extract.
