Hello guys, I am new to AAC. I am working on a small sensor based project.
I am using a hall effect sensor (461C), which only respond to one polarity, thus producing a square wave. My supply is only a single rail 5V supply, so my square wave has amplitude of 5V. A magnet is attached horizontally to a motor and brought close to the sensor, which produces square waves of varying width according to the supply to the motor(which is between 0-3V)
Since it is a analog project, I have to convert frequency to analog dc voltage. On trying out different circuits such as peak detected, voltage doubler circuits, I was advised to use 4046 for FCV, since frequency that I get form my sensor is very small only between 0-100Hz.
Can I ask you to advice me one how to use 4046 as FCV and if possible a circuit diagram can help me.
Thank you in advance for all suggestions and help offered.
