The derivative ([Wikipedia](https://en.wikipedia.org/wiki/Derivative)) integration creates a sensor that "smooths-out" another sensor (the **source sensor**).
|
||||
Derivatives of the specified sensor will be averaged in a given time window with a Simple Moving Average algorithm weighted by time. This is, for instance, useful for a sensor that outputs discrete values or to filter out short-duration noise.
|
||||
Derivative sensors are updated upon changes of the **source sensor**.

For sensors that reset to zero after a power interruption and need a "non-negative derivative", such as bandwidth counters in routers, or rain gauges, consider using the [Utility Meter](/integrations/utility_meter/) integration instead. Otherwise, each reset will register a significant change in the derivative sensor.
