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. In addition, an LED on the module lights up when the threshold value is reached.
You'll find further information and sample-code here.
