| ID: | 308 | | Title: | Water Level Switch - http://ozreef.org/diy_plans/electronic_projects/water_level_switch.html | | Description: | Basically this unit will switch on/off anything that is 240vAC that is plugged into it. For example, I am using it to switch off my sump return pump if my main tank if it is about to overflow. This is done by having the float switch on the lip of the main tank and when the water rises the float goes up and switches off the power to relay, which inturn switches off the pump. This is done safely with no 240vac in contact with water due to using the relay, which can be power by any simple 4-32vDC power supply (I used a mobile phone recharger). The relay will also never fail as it uses no mechanical parts to switch the 240v line (which also means its completely silent!). | | Category: | Electronic Projects | | Link Owner: | KingVinnie | | Date Added: | May 27, 2008 09:59:27 AM | | Number Hits: | 68 | | |
