Question

What is the voltage of the Hall effect sensor?

Answer 1

The voltage output of a Hall effect sensor typically depends on the specific type of sensor and its design. However, in general:

1. Voltage Output: Many Hall effect sensors produce a voltage proportional to the magnetic field strength. This voltage can range from a few millivolts (mV) to a few volts (V), depending on the sensor's design and the supply voltage applied to the sensor.
   

1. Supply Voltage: Most Hall effect sensors are powered by a DC supply voltage, commonly between 3V to 24V. For example:
   

   - Some sensors use 5V as their supply voltage.
   - Others might use 12V or even 24V.

1. Output Voltage Range: The output voltage (the signal voltage) is usually in the form of a small analog signal or a digital output:
   

   - Analog Output: The voltage output varies linearly with the magnetic field strength. It can range from 0V to the supply voltage (e.g., 5V) or from a fixed reference (e.g., 2.5V) depending on whether it's a unipolar or bipolar sensor.
   - Digital Output: The output could be a logic level, such as 0V (low) and 5V (high), especially in digital Hall sensors (like a latch-type or switch-type Hall sensor).

It's important to check the datasheet of the specific Hall effect sensor you are using for precise voltage characteristics.
