Hi All,
Im building a shower timer because the kids are spending way too long in the shower. I want to use a picaxe chip. I will program it to a timer start when the water starts to flow (Water Flow Sensor) count 5 minutes and then shut the water off using a solenoid valve.
Im just wondering can anyone advise what water flow sensor I can use and how to interface it with the micro controller. Also will I have to use a relay to control the solenoid? One more question: What actual picaxe micro controller will I use?
This project will be perfectly safe: I will incase the picaxe in a waterproof case in the bathroom and my brother is an electrician so I will have him do all mains wiring.
Thanks in Advance,
Emmet
