I am going to start a project using the 7 inch display sold by GHI, along with a UCM module. I have the UC5500 with wifi, and I will get the dev board even though I have the smaller breakout already. The application will monitor a water system at my house, including water well levels, water tanks levels, maybe water flows using a separate micro counting pulses, most of the stuff is simple digital inputs or analogue 4-20ma stuff. I want to store data about the system, probably using an sd, no need to put it in the cloud.
The display will be a place for the user to interact with the program, view water flows and water levels, configure the system (will have the ability to fill rainwater tanks using the domestic water supply etc, the system has a reverse osmosis system for making fresh water from the brackish well supply).
So I am wondering if I am better of getting the G400 module, rather than using the 5500 module I already have, does anyone have any experience using the 7 inch display with either module performance wise? I can use either wifi, or hardwired network connection from the display unit, mounted in the house, to the water system located about 100 feet away in a separate building. In the separate building, I can use another micro of some kind connected directly to the sensors and recording data, perhaps polled by the main system at the house, and recorded to SD. The only thing that needs to be “real time” would be the hall effect flow sensors, and they could be tasked to their own dedicated micros that would just count flows and communicate with the main micro using I2C or serial.
Any comments on appropriate hardware would be appreciated, thanks!
