Design & implementation of a linear IC based low cost anemometer for wind speed measurement

A self-design anemometer can provide accurate reading compared to any other anemometer which is found in market. Any adjustable speed drive uses an incremental shaft encoder or a sensor and an electronic circuit for rpm as well as wind velocity estimation. The method of counting pulses generated by a sensor in a period of time produces a high precision velocity or rpm estimate in the high speed range. The purpose of the project is to measure wind speed with a self-design low cost anemometer in between campus-4 and 5 of American International University-Bangladesh located in Banani, Dhaka at 23.794503°N 90.406175°E and 23.794278°N 90.405611°E where natural wind is available and it is possible to make small scale power generation. This anemometer is able to measure the wind velocity and provide voltages which are linearly proportional. Besides efforts have been taken to reduce the cost of anemometer as much as possible.
