Hello everyone!!! I've been assigned to write a paper about aquarium automation with plc for a course at university. No actual hardware will be bought so I have to describe the system and show the program in theory. So basically I want the system to perform the following tasks:
1) Temperature Control(cooling and heating when certain values are reached) Should I use an analog input for this one?
2) PH Control (trying to keep the PH stable opening valves that will pour the agents that will adjust it) Not sure how this will work cause PH should not change rapidly. I suppose I need an analog output to control the valves???
3) Lighting Control I suppose simple timers should do the trick
and a few other tasks such as alarms, water level etc which are fairly easy. Any help is appreciated
