Water Leak Detector – Normally Open / Normally Closed

Water leakages are always bad news and result in increased expenses as your precious water escapes from your container. But fortunately, you can install your own Water Leak Detector that will alert you of any leakage. Makers enjoy the DIY applications that these modules make possible. Coupled with a smart microcontroller like Arduino, this DFRobot Water Leak Detector could also signal your cell phone with a warning notification, so you can stop the leak as soon as possible.

The Water Leak Detector utilises relay output signals on either a normally open or normally closed design. Enclosed in a waterproof shell, the detector module should be fixed to the side of your container either above or below the water. When set to normally open, if the two probes in the Water Leak Detector Module touch the water, then the built-in relay is triggered. When set to normally closed, the built-in relay is triggered if the water level passes lower than the two probes. The design you chose is dependant on the set up of your container or watery project. An alarm sounds when leakage is detected and with a connector microcontroller, you could set it to automatically turn off the tap. The Water Leak Detector can lead to fascinating applications which allow you to monitor your fish tank, or automatically stop your bath water from flowing over the edge.

As self-proclaimed “Robo-holics”, DFRobot is a company comprised of over 100 staff members, of which 30% are engineers who love to build robots. It was started in 2008 with the goal of embracing and promoting open-source hardware, with a core focus on Arduino, Raspberry Pi and their very own LattePanda development boards. Since then, DFRobot have manufactured over 1300 unique modules, sensors and components that all work together and complement each other, allowing users like us to enjoy a full spectrum of cutting edge robotics and electronics without having to pay premium prices.

With the primary goal of developing and manufacturing great quality products, while making them accessible to as many people as possible, DFRobot are rapidly becoming one of the most common-place brands in the world of open-source robotics and electronics. With more than 1300 products developed in-house, and an impressive range of different categories and specialisations, there are few brands in the world who can compete in terms of quality, accessibility and genuine innovation.
