A1324 Hall Effect Sensor

Product Description

The A1324 replaces the A1321 which is no longer being manufactured. The A1324 is an improved version of the earlier sensor and works in exactly the same manner. It has a wider supply voltage though, and has a rated supply voltage from 3.0V to 5.5V (with an absolute maximum of 8 volts). They are rated at 5mv per G (gauss) and are dead simple to use. Just hook up the output to an ADC pin on a BBB, Arduino, JeeNode or other microcontroller.  The datasheet suggests a .1uf (104) decoupling capacitor as close the device power supply as possible. These simple sensors really excel as current sensors (since any AC current in a wire generates it’s own magnetic field) and I easily was able to sense the line current from my electric coffeepot and toaster, just from mounting the sensor next to the line cord, with no electrical connection. With a bit of practice and tweaking of my code I was able sense whether a 100 watt bulb in a lamp was on or off. Our new Current Sensor uses these devices with some more gain for “completely isolated” current sensing. Resources A1324 datasheet
