func PollSensors

func PollSensors(ctx context.Context, updater func(), interval, stdev time.Duration)

PollSensors is a helper function that will call the passed `updater()` function around each `interval` duration within the `stdev` duration window. Effectively, `updater()` will get called sometime near `interval`, but not exactly on it. This can help avoid a "thundering herd" problem of sensors all trying to update at the same time.
