  • you misspelled read

  • No - try googling reed switch

  • what is it doing when sensed the magnet?

  • I am just using a reed relay and the PCF8574 I/O chip

  • you know you could have just used the compass sensor, since it detects the earth's magnetic pole.

  • I am not sure I understand what you mean? The magnetic sensor can detect the presents of a magnet - it has nothing to do with a compass sensor or the earth's magnetic field
