Ez Robot community I wanted to introduce my latest application of this system. Some members hear already know I keep two salt water aquariums one coral which unfortunately died off and my predator tank. Sea life needs delicate balance maintained in their little ecosystem. Things like light spectrum , temperature, ph balance , current of water , nitrate and ammonia levels and calcium levels. These things take a practiced hand to maintain. I am building a new system and using ez b to monitor salinity, nitrates and ammonia, temp , water current flow and the ph. The ADC ports are useful for these and EZ board can control the current and switching to a backup power supply ( a apc for computers inside the cabinet to keep ezb and pumps powered). Also the ezb can turn on and off night , morning , day , and evening lighting settings. With a custom injection device im designing ezb can provide nutrients , calcium and even medicine if levels are out of wack. I started the build today and I am very excited!
