When the sensor sampling time interval is reached, for example 2 minutes, the Sigfox node will wake up and switch ON
the power supply to supply the energy to external sensor to start the measurement. Depends on the type and
characteristic of external sensor, the sensor will take a certain time to finish the measurement.
Once reading the value, it can be scaled to any engineering value by the following formula:
Y = aX + b
Where:
X: the raw value from sensor
Y: the calculated value will be sent to Sigfox base station in the payload data.
a: constant (default value is 1)
b: constant (default value is 0)
So, if there is no user setting for a and b ==> Y = X
