The Magnetic Sensor (compatible with Lego Mindstorms NXT) will enable you to build robots that can detect magnetic fields. The sensor detects magnetic fields that are present around the front of the sensor in a vertical orientation.
The sensor detects magnetic fields when the orientation of the magnet is as shown below.
When the orientation of the magnetic field has north uppermost, the reading will increase. If the magnet is presented sideways, it may not be detected.
The Magnetic Sensor connects to an NXT sensor port using a standard NXT wire and uses the analog sensor interface. The sensor can be read up to approximately 300 times per second.
The Magnetic Sensor is housed in a standard Mindstorms sensor housing to match the other Mindstorms elements.
To quick test your new sensor, plug it into port 1 of your NXT brick and select View – Ambient light – Port 1. As you bring a magnet close to the front of the sensor, you'll notice that the readings will change as the magnet gets closer.
