Raining on my parade!!

A project log for Aquarium controller / home automation

I am building an automated aquarium controller to fit into my home automation system.

I have just purchased a Rain sensor for 50 pence (UK money) - nothing right!

I have this idea about having a rain sensor outside and my HoCo system telling me (buzzers, strobes maybe even a voice command mmmm that is an idea) that it is raining after I have gone and put my washing out to dry!

This introduces a new type of sensor, namely, a non-fail-device. You see, all my sensors are in my system to tell me if something has happened (water too high, water too hot etc). Well this type of sensor (above) does not have a fail state. It only comes into play if another sensor and itself is in a certain state. For example if i have my washing out to dry AND if it is raining. So how can I achieve this. Well, simple really, as I have designed such a nice modular system. I will attach to a new project box a rain sensor and a couple of buttons and a couple of led lights.

This is how the sequence will work.

QED! (or have I missed something? - I always think this if something has worked out rather too easily!)
