i was searching for a current sensor to use in a car (for a racing team) to sense up to 150 Ampere
and i found the ACS 758 , and the one that is available in my country (Egypt) is ACS 758 100B
here is its datasheet
i understood that it can detect between -100A and 100A
my question is can this sensor sense my 150 A if i use it between 0 A and 150 A or 200A(as it is Biderictional) ?
if not , what is the meaning of biderictional in sensors ? and if there is any links to help me understand why it can't sense up to 200A from 0A, please Help.
final question , is there any other sensor to use in the car and use it with Arduino,please help.
Thanks in advance.
