It’s not hard to find out how to open a 12v solenoid, that controls water through a kitchen sink type pipe but I want to do the following:
- If the outside temperature gets below a certain temperature (a variable set by me):
a) The solenoid opens for a certain amount of time (time set by me)
b) The solenoid opens a certain number of times within a certain period of time.
Example:
The outside temperture reaches 25 degrees farenheit
The solenoid opens once, for 10 seconds, every 20 minutes.
If the outside temperature reaches 10 degree farenheit the solenoid opens once, for 10 seconds, every 10 minutes.
So I want a wi-fi enabled, battery powered outside sensor that deals with below zero temperatures that plays nicely with a board that reads the outside temperature a programmable number of times per hour and when the temperatrue reaches a certain (programmable) temperature it opens a 12v solenoid a programmable number of times within a programmable period of time.
I would like to be able to set the variables with my cell phone as this device will be installed under a kitchen sink.
I can think of a number of cool things to keep track of like:
a) When (date and time) the solenoid opened. Data entries can be easily deleted by the user.
b) At what outside temperature the solenoid opened for the firtst time on any given day.
c) When the temperature rose above the temperature necessary to start the solenoid oponing process.
I have not found an online example of a setup as complicated as mine.
Your input is appreciated!
