» Ga 01: Temperature Sensor

In this example the Gases 2.0 board is turned on and the MCP9700A temperature sensor read every second approximately, printing the result through the USB.

Required Materials

1 x Waspmote
1 x Battery
1 x Gases 2.0 board
1 x Temperature sensor (MCP9700A)

Notes

* Remember to connect the battery to Waspmote for proper operation
* The connection of the sensor is described in the Gases 2.0 technical guide
* This example can only be executed in Waspmote v12
