Abstract
A rainfall detector for detecting a set amount of rainfall and which functions to interrupt the normal operation of an automatic sprinkler or irrigation system upon detection of the set amount of rainfall, includes a rainwater-collection tray having an opening and mounted so that the portion of the opening exposed to rainwater during a rainstorm is adjustable. The rainwater-collection tray may be slidably mounted below a detector housing which houses a switching circuit with two sensors extending into the tray, and which serves to block the rain from the open portion of the tray beneath the housing. Thus, the portion of the tray opening exposed to rain is adjusted by sliding the tray so that more or less of the opening is covered by the housing. The tray may also include posts extending upwardly from the bottom of the tray and terminating below the top edge of the tray for preventing debris from filling the rain-collecting portion of the tray.
