A magentic field will be measured by the sensor based on an 49E hall sensor, and displayed as an analog voltage rating aswell as digital signal when a certain threshold is reached. The sensitivity of the sensor can be regulated with a potentiometer. With individualized codes, the sensor will able to be used on other devices. This module can either be solidly soldered or be used on a breadboard. In addition, an LED on the module lights up when the threshold value is reached.
You'll find further information and sample-code here.
