Como medir el viento muy fácil. Anemometro simple y con ARDUINO
Fabricating a Basic Anemometer
Introduction to the Project
- The presenter welcomes viewers and introduces the project of building an anemometer, a device for measuring wind speed.
- Two versions will be created: a basic one using a multimeter and toy motor, and a more advanced version with Arduino for direct wind speed readings.
Materials Needed
- For the basic model, materials include measuring spoons from powdered milk or soap containers, or ping pong balls for blades.
- A lightweight motor is essential; it can be salvaged from old toys or CD/DVD players. The presenter emphasizes finding motors that spin easily.
Assembling the Anemometer
Constructing the Blades
- The blades are attached to the motor's shaft using glue after creating holes in them for fitting.
Motor Setup
- A PVC pipe serves as support for the motor, which is secured with a magnet to attach it to a vehicle's roof.
Calibration Process
Initial Calibration Steps
- To calibrate, mount the anemometer on a vehicle’s roof and connect it to a multimeter set to measure millivolts.
- Record voltage readings at various speeds (from 10 km/h to 100 km/h), ideally on a calm day without wind.
Data Analysis
- A linear graph can be plotted based on collected data points correlating voltage readings with wind speeds.
Integrating Arduino for Enhanced Functionality
Connecting Arduino
- The setup involves connecting the motor's positive lead to an analog input on Arduino while ensuring proper grounding.
Code Implementation
- The presenter discusses adjusting code based on calculated slope values derived from calibration data.
Final Adjustments and Testing
Ensuring Accuracy
- After coding adjustments, testing involves comparing displayed speeds against actual vehicle speedometers during test drives.
Additional Features
- The project includes functionality for recording maximum wind gust speeds, resettable via an Arduino button.
