. A shorter time period allows
you to observe small changes with more detail. But it also consumes memory more quickly,
to need to communicate with the data collection system more frequently
. This can have an impact on both battery life and the cost of the

These are divided equally between all active pulse
channels. If only one channel is

The sample rate is based on how quickly you expect the inputs to change. Faster sampling
rates are used for quickly
changing inputs but results in higher power consumption. Too slow
f a sampling rate can lead to errors.
Debouncing and sample rates are discussed in more detail later in this document.
