Quicksand micro-electronics / Mbed 2 deprecated QW_Temperature_Light_Monitor

Code example to regularly report light level and temperature over Sigfox on the QW dev kit

Dependencies:   QW_Sensors mbed

Fork of QW_Temperature_Light_Monitor by Lieven Hollevoet

This is a code example that demonstrates sending the light level sensor and temperature sensor output over Sigfox at regular time intervals.

The payload that is sent over the network consists of 3 bytes:

  • two bytes light level reading
  • one byte temperature reading.

Use this code example as a start to connect your own device over Sigfox with the QW development kit.
