Question

4) A paddle wheel flow sensor that uses hall-effect sensors is used to measure the flow of a fluid and shown in Figure 3. The CPR of the hall-effect sensor is 16 however the maximum flow rate resolution should be 512 pulses. The maximum rate of flow relates to 4 rounds per second of the paddle wheel. The output from the hall-effect sensor is a 5O% square wave -sv to +SV. Develop a design (mechanical and electrical) that provides a digital logic interface level to a micro ler to read the frequency of the pulses. sensor Figure 3
