Hall sensor error, all 3 sensors stuck on 2.79v?

<< < (3/3)

Overview: The reason you need to add the current limiting resistor is because typically the controller provides the logic voltage to the output leg.
The sensor uses the 5vdc direct power supply input only for the actuation of it's "contact", which in effect shorts the logic voltage present on the output leg (provided by the controller, or in this case thru a limiting resistor to direct input power) to ground or not. Switching from 5vdc verses 0vdc depending on magnetic gauss present. (off or on)
