Hi,
i am new to arduino, but not new to automatic controllers.
i built in the past a controller that control my fish tank using a unitronics V350.
i now what to built the same options that i have today; using the arduino.
i need some help with a list of thing to get started.
i want to achieve this options:
water change base on days of week selection, start time and duration that the solenoid valve will open to drain water out.
float switch (1/0 digital input) that determined if the level of the tank is low, if yes, its need to open another solenoid valve to fill water.
light control, base on start hour and end hour.
temp control, for heater and chiller. using a set Temp like 24C, if its got to 25C the chiller is ON until 24C and if the Temp got to 23C it will ON the heater until 24C.
touch screen to be able to set all the Parameters for the controller, and of-curse to see whats ON and read input data like Temp, PH and so.
i have a PH transmitter in my old controller, its 4-20MA output. but i am open to new things to read PH data, base on that data a solenoid valve should be open or close.
log data reading on SD card in CSV format.
Web Server to view the real time data from my iphone.
all the electricity like heater chiller light etc uses a 220V.
so i will need a relays.
this i what my unitronics V350 dose today, but i want to achieve the same thing with arduino, because i want to use the V350 as an automated house controller.
so what part list do i need to buy? i got lost with all the parts out there.
Thanks in advance.
Ofer.
What are you using to control the valves? Servos? Motors?
Analog in pins to read thermometer.
How much voltage does the heater/chiller require?
How about a picture /online URL links to the products you have?
Do you want it to access the web on the phone or the phone itself?
Do you want the phone on wireless communication (emails/text messages) or wire communication (Serial)
→ you might want to take a look at some of the library choices http://arduino.cc/en/Reference/Libraries
check out the DateTime library to use instead.
the PH transmitter uses anlog input of 4-20 MA and output of 24V with relay of 220V for the selonoid valve
i have another PH probe and want to try to use the pHduino what parts will i need for that?
i dont want to disassembly the V350 controller that i have now until i bulit the arduino controller because the V350 is working on my fish tank now, so i have to built from scratch.
ofcurse i will need to buy more staff to add in the futher. but i want to start with somthing...
lets say that for the start, i want this options:
2X light control
Temp control using a temp sensur in the tank that controls the 220V heater and 220V chiller.
PH control using pHduino what parts will i need?
water change control drain water base on day of week, start time and duration of the drain.
filling water digital input is a float switch.
emails on errors like high temp or low water power off etc (wireless communication and celular moden with AT commands that i already have).
logs of all the ON OFF of the heater chiller lights an reading of temp and PH.
do you think i miss anything?
can i start ordering this items?
please advise about 1-6 items and 14 or 15 which should i buy?
all in this list will work together?
thank you.
Oferelijah, I was just curious how your project is going. I am doing something similar for my planted tank that started with controlling the LED lights, then added other functions. Now I am looking to add temp and pH monitoring. Any "lessons learned", pictures and/or schematics would be greatly appreciated.
