Inline condensation alarm system for a central air conditioning unit

摘要

An inline condensation alarm system used to detect condensation backup within the condensation line of a central air conditioning unit. The two stainless steel screws complete a circuit between the piezo buzzer and battery within the PVC pipe installed to the condensation line of the unit. Once condensation backs up to the top contact point the alarm is set off. The alarm would allow time for the user to clear the blockage prior to spillover from the condensation line.
