			I did a very similar project for home automation in college; unfortunately I don't have the files/code anymore. I used Arduino, several sensors and actuators, and the touchscreen display. Here's some information about the display:

			The company 4D Systems offers a wide range of Arduino compatible touchscreens up to 7" - [https://www.4dsystems.com.au/products]. The displays can talk to Arduino using different communication protocols, such as Serial, I2C, and SPI. Some fairly simple examples along with code and step-by-step instructions can be found in their website - [https://www.4dsystems.com.au/appnotes]. A specific example is this very simple "Hello World" application - [https://www.4dsystems.com.au/downloads/Application-Notes/4D-AN-00092_R_1_0.pdf]. An advantage is good documentation and excellent customer support from 4D Systems; but there are also disadvantages:
			*Proprietary software (but still "gratis") is needed to program the display. The software is not available for Linux.
			*Displays are relatively expensive (capacitive touch, ultra bright display with bezel full kits are $99 - $200).
			*Some known issues with the micro SD card holding the image files in some of their products; the files can get damaged after ~50,000 read cycles, so there's a need to format and re-write the files every now and then. They supposedly improved this by using "Industrial Grade" micro SD cards. I noticed an improvement, but it didn't fix the issue for good.

			I recently used this combination (Arduino + 4D Systems display) for an industrial automation project as well; if I find the files/code this week, I can upload to Github and post the link as an example that goes beyond what you would find in the links I posted.

Hi,

We have recently built the Seed Eco-Home - see our Kickstarter from last year:
https://www.kickstarter.com/projects/622508883/open-building-institute-eco-building-toolkit

We are implementing a monitoring system for its off-grid utilities. We would like to implement an Arduino-based monitor that shows water, power, and bio-digester gas levels.

Would you be interested in helping us as a subject matter expert - in developing this Arduino-based monitoring system?

Thanks,
Marcin
