DEPARTMENT OF MPE(ME)AUST

OBJECTIVE

To measure wind speed. To measure temperature. Constructing a low cost anemometer.

ANEMOMETER

Device to measure wind speed.Additionally – Temperature measurement. Pressure measurement. Wind direction.

TYPES OF ANEMOMETER

Cup anemometerVane anemometerHot wire anemometer

LASERDOPPLER anemometer.

Sonic anemometer.Ping-pong ball

anemometer.

WHY CUP ANEMOMETER

Accurate result than other anemometer. Application range breeze to hurricane. Easy available components. Easy to install. Low cost.

DESIGN

CAD DesignSolid works 2011 usedDivided in two

sections-parts and assembly

Part design of cup with arm

Final Assembly of the Cup Anemometer

Manufacturing(Material

Selection)

Base box : Wood Reason- low costLess weightEasy cutting ,drilling.

Cups, arms and shaft: Aluminium

Reason- Light weight Corrosion resistance

highAttractive outlook.

Manufacturing (Components)

Mechanical components: Wooden box Bearing Cups, arms & vertical shaft.

Electrical components: Arduino Uno Reed switch Magnet LM-35 LCD display Toggle switch Battery 10-k pot Male-female wire

Full view of the project

Working methodology

Temperature :LM-35Uses voltage

difference

Wind speed:Pulse from reed switch

Pulse is being sent to arduino

Number of rotation counted

Using v=wr ; speed measured.

CALIBRATION

Calibration : Single point calibration Standard anemometer

used

APPLICATION

Application: Wind energy conversion Weather station In marine travel Industrial worksite For structural design

ADVANTAGES

Advantage: Cheaper Easy to construct Easy to install portable

LIMITATIONS

Limitations: Inappropriate for very

high wind speed. Using wind tunnel for

calibration would be better.

FUTURE EXPECTATIONS

Future expectation: Pressure measure Wind direction Using hall effect sensor

would be better.

CONCLUSION

Important device for wind energy conversion

project helps us to understand difference between theory & practice.

Special thanks to our honorable project teachers.
