General description

The sensors are active on the Events Sensor Board while Waspmote is in Sleep or Deep Sleep mode. When a sensor changes its output signal to a "high" value, a signal is generated, which wakes the mote from its low consumption status and tells it which sensor has generated the signal.
If Waspmote were in active mode (on), it would receive the interruption and could respond to it in the same way as the previous case.
Operation:
The board allows simultaneous connection with up to 5 sensors whose outputs are combined in an OR logical gate which implements a change in the interruption bit which wakes the mote. You can also connect different Digital Bus devices, in addition to a relay output and a relay input.
The sensor that has interrupted the mote is identified in a shift register which can be read by Waspmote once it is in normal operation.
