Each built-in sensor class comes with reasonable default settings. In case you want/need to customize any of those settings, after having registered the sensor, you can retrieve it back and call set functions common to all the sensors or specific for a given class.
To do so, use `nodeManager.get(child_id)` which will return a pointer to the sensor. Remeber to cast it to the right class before calling their functions. For example:

Register a rain sensor connected to A0. This will be powered with via pins 4 (ground) and 5 (vcc) just before reading its value at each cycle, it will be presented as S_RAIN. sending V_RAINRATE messages, the output will be a percentage (calculated between 200 and 1024) and the value will be reversed (so that no rain will be 0%):
The following sketch can be used to report the rain level and the soil moisture based on two sensors connected to the board's analog pins (A1 and A2). In this case we are customizing the out-of-the-box SENSOR_ANALOG_INPUT sensor type since we just need to measure an analog input but we also want to provide the correct type and presentation for each sensor.
We register the sensors first with registerSensor() which returns the child id assigned to the sensor. We then retrieve the sensor's reference by calling get() so we can invoke the sensor-specific functions, like setPresentation() and setType().

In this example, the two sensors are not directly connected to the battery's ground and vcc but, to save additional power, are powered through two arduino's pins. By using e.g. setPowerPins(4,5,300), NodeManger will assume pin 4 is ground and pin 5 is vcc for that specific sensor so it will turn on the power just before reading the analog input (and waiting 300ms for the sensor to initialize) and back off before going to sleep.
For both the sensors we want a percentage output and with setRangeMin() and setRangeMax() we define the boundaries for calculating the percentage (if we read e.g. 200 when the rain sensor is completely into the water, we know for sure it will not go below this value which will represent the new lower boundary).
Finally, since both the sensors reports low when wet and high when dry but we need the opposite, we set setReverse() so to have 0% reported when there is no rain/moisture, 100% on the opposite situation.
