Drives me slightly crazy seeing lawn sprinklers going while it's raining and humid.. The underground sprinkler system my parents installed 30 years ago has a sensor to prevent that, it's certainly not unusual. It would be interesting to see rain sensors for regular sprinters although I'd be shocked if they didn't already exist.
