Unlike other Hall-effect switches, either a north or south pole of sufficient strength will turn the output on; in the absence of a magnetic field, the output is off.

The A1101 Hall-effect switches include the following on a single silicon chip: voltage regulator, Hall-voltage generator, small-signal amplifier, Schmitt trigger, and NMOS output transistor. The integrated voltage regulator permits operation from 3.8 to 24 V.

what's the best way to detect the magnet? Use anther magnet. But it's not sensitive enough. You have to feel it by youself.Right！This Hall sensor knows whether there is a magnetic object nearby or not. And it correctly tells you through ditigal output.See below picture for a quick demo!

The US1881 is an integrated Hall effect latched sensor. That’s nice but what does it do? Holding a magnet near the sensor will cause the output pin to toggle. This makes for a robust presence sensor. A reed sensor also works nicely, but can be limited by the glass encapsulation and size. A hall effect sensor is much smaller, but can handle less current than a reed switch.

When you want to measure AC current it is impractical and hazardous to cut in to your live wiring. The analog AC current sensor developed by DFRobot is a good solution to this problem. Using induction you can measure AC current without intrusive methods. Place your AC wire inside the unit, connect the unit to the sensor board using the 3.5mm jack connector and connect the sensor board to an analog input on your microcontroller. Use this sensor to measure AC motors, lighting equipment, air compressors or any other devices that use AC current.
