The Reed Switch is capable of detecting magnetic fields. Normally, the switch is open, but when a magnetic field is applied to the switch it closes. The Reed Switch is connected in series with a pull-up resistor.
The reed switch example is tested with both a magnet present and without a magnet present. The magnet is placed directly above the reed switch. This examples wakes up with a frequency of 64 Hz. If a change in the state from last time is detected, the System CPU is woken up and alerted. Depending on the state of the reed switch, one of two LEDs will light up.
Average Current Consumption | Unit | |
---|---|---|
Without magnet present (64 Hz) | 1.3 | µA |
With magnet present (64 Hz) | 1.4 | µA |
