» Ev 09: Socket 8 Flow Sensor

In this example we turn on the Events Board v20 waiting for an interruption from the flow sensor placed on socket 8, reading the sensor and printing a message with its value when received.

Required Materials

1 x Waspmote PRO
1 x Battery
1 x MiniUSB wire
1 x Events Sensor Board
1 x Flow Sensor

Notes

* Remember to turn on the manual switch for socket 8 in the Events 2.0 Sensor Board
* The position of the socket 8 jumper must be configured to select socket 8.
* This example can only be executed in Waspmote v12
