I have hall sensor that can measure current upto 25 A .with analog output 0~5v. I am using Arduino mega Board for programming. There are totally 30 Hall sensor and where arduino mega has 16 analog channel. Because of this i am planning to use multiplexer circuit
1)Is above circuit is write to build multiplexing circuit??
2)How Multiple analog output values are read
3)What is purpose of selector pins S0,s1,s2 . it say that depend on state of pin it read value . is it true or false. means to say if s0=s1=s2=0 it read analog out put of hall sensor 1 , if S0=0 s1=0s2=1 it read HS4 it is correct or not.
4)using multiplexer i can read one value @ time but multiple IO connected or using delay in program i can say read value after every 1000ms
