I am thinking to start a new project for aquarium, I know what some people will say, why this guy does not copy from a google site?
At first, I believe that just copying is not a creation and I would like to create something in a low cost project.
Second one motive, I would like to create a proactive monitor to change parameters, send messages when it happens and show water parameters (this last, as the most os projects I saw).
Normally to monitoring an aquarium some parameters are necessary, like:
KH (water hardness)
Salinity (Reefs case)
Presence of metals and others (Mg, PO4, NH3, NO2)
CO2 (Fresh water case)
I would like to ask your help to create an Arduino project to meter all those above and create a proactive mechanism to change parameter based on programing. For example, If the temperature rises more than 26ºC (78,8ºF) the project could turn on chiller until themperature decrease to 26ºC. For chemical it will spend more research because depends of some calculations.
Could you guide me informing which Arduino parts I need to purchase to complete my project? There are these sensors?
Many thanks in advance!
