The 3144 is a hall sensor, which means that if it detects a magnet, the output goes low; otherwise, the output remains high. A magnetic field generated by an electromagnet or a permanent magnet powers Hall effect devices. The user must calibrate the output voltage based on the supply voltage. The output voltage varies in direct proportion to the magnetic field strength.
