Integrate the Nextion Display.
Oct 2, 2022
Nextion is a Human Machine Interface (HMI) solution. Nextion displays are resistive touchscreens that makes it easy to build a Graphical User Interface (GUI). It is a great solution to monitor and control processes.
My Nextion display module, has a size from 2.4”
The Nextion has a built-in ARM microcontroller that controls the display, for example it takes care of generating the buttons, creating text, store images or change the background. The Nextion communicates with any microcontroller using serial communication at a 9600 baud rate.
So, it works with any board that has serial capabilities like Arduino.

I MUST have one of these!! Do you sell them? If not, can you list the components? I like the design too.
First of all, I want to present a construction manual and of course the parts list as well. I'm still looking into the possibility of offering a kit.
When you do, let me know so we can review and promote it!!
I Like.
I'm going to buy these parts, which is also a DIY set. It's great. Thanks for sharing.
Impressive work. I'm excited in following your progress.
is it possible to ad a preassure sensor for tankbags ?
That would certainly work too. The Arduino has even more inputs. Here you only have to choose whether it should be a digital or an analog pressure sensor.
I can't find the right pressure sensor for this application,do you have a hint ?
I'll research what's available on the market
Uwe, did you find any fitting pressure sensor?
Most interested!
Uwe, Thank you. In Ch 2 you noted “ The flow meter I use has a flow range of 0.05 -3.0 L/min and the repeatability of frequency response is +-0.5% (at the same operating condition)”. Can I assume this accuracy is representative of the total volume delivered over time?
I might consider building one using your data. If so, how can one reimburse you for your efforts? Are you considering selling them as a kit?
Thomas, the accuracy is described in the manufacturer's data sheet. I can also say that it is absolutely reliable. You can draw good conclusions from the amounts of fuel refueled after each flight.
I don't offer it as a kit. But you can send me a PM. I'm sure we can find a good solution.
