I need to know the manufacturer or the company of this magnetic sensor. The only thing I know about it, is the pinout. Does anyone has ever seen this type of sensor?
The only text in the PCB is "BS" in the layer show in the picture and "LS SM 4.02" in the bottom layer. The output of this module is in voltage and it has a 2.5V reference pin.
I've searched many company pages but I haven't had any success.
