Hi,
I want to measure wind speed using a simple fan and IR sensor.The output of IR sensor is 0 and 5V.I used a slit having 20 wholes in it.I have programmed in mikroC. When I rotate the fan with hand sped changes but at rest speed is constant which is 53 m/s. I thing there is some thing missing.Kindly help me in this.
