What is the magnetic field range detected by the magnetic sensor?

We all know that the magnetic sensor detects the intensity of the magnetic field and converts it into electrical signal output. So what is the magnetic field intensity that each magnetic sensor can detect? In the figure below, we list the magnetic field strength detected by various types of magnetic sensors, such as Hall sensors, magnetoresistance, giant magnetoresistance, magnetoresistive diodes, and magnetoresistive transistors.

If you choose a linear Hall sensor, it can detect magnetic fields ranging from a few Gauss to hundreds of thousands of Gauss. If you want to detect geomagnetism or a weaker magnetic field, magnetoresistance may be more suitable.

If you don’t know how to choose a suitable magnetic sensor, Ouzhuo will provide you with product recommendations and selection.
