💬 EFEKTA Temp&Hum sensor(ver. nRF52 )+E-Ink display

[heinzv]

are you satisfied with the nRF52xx and does it work properly? I hope sometime we get the project infos to make some sensors too :-)

[berkseo]

@heinzv

I'm satisfied, it work perfectly. I found ready-made modules that can be used by every user without learning, in the Arduino IDE, this was my main task. Now the self-made prototype is on testing, PCB ordered in production. After some time, the development will be available.

[heinzv]

@berkseo That looks awsome, great work. One of the best projects (HW and SW) I have seen. Exactly what I need!!! I can't wait to get your PCB layout and the project code.

[heinzv]

@berkseo once I got it/use it I will make a donation (I think you deserve it)

[berkseo]

Received printed circuit boards. Soldering tomorrow :))

[jeti]

Looking good! Please keep up the awesome work.

@berkseo any chance you can provide a brief feedback?
What is your status on the software side?

For nrf52832 was tested software developed for the atmega328. Need to alter the fonts and graphics, to improve, because this chip have more opportunities. This is not difficult. There will be an update soon.

@berkseo thanks!

[berkseo]

update,

It remains a bit to fix the program(improve graphics), as the demo uses software from the version on atmega328

@berkseo awesome! Great work!
One question: the high temperature is a result of testing? So with a long enough sleep time the temp will be accurate?

Don't quite understand the question. The chip is not heated. No matter how much the device sleeps, the temperature sensor also sleeps. A digital temperature and humidity sensor is used.

@berkseo on the second restart the temperature shows 46°C that's why in wondered of this is caused by testing. As during "normal" using this should not be an issue

[berkseo]

@jeti
On video, now I understand)). Used software for the Atmega328 , so was error. This chip is very fast. I fix it.

[jeti]

@berkseo ah thanks. If you need somebody to test. I would be happy to do so.

Once the code is available I would order 10x PCB's.
Also, do you have a link to the nRF52832 module? (a 840 version would be also very nice :-))

ok, I just odered the 5 PCB Sets.
Beside the link to the nRF52832 Module, please provide also the link to the e-Paper Module.

Really nice design..

Could you please post the schematics / board files as well, as this is a openhardware site.

Also if you upload the gerber files directly (not in a zip / rar file), then the openhardware.io site is able to render 3D views of the boards etc.

Code in the work. BOM added.

@tbowmo
Thank you for rating. I will lay out the scheme in the near future, it needs to be drawn :). 3D-model does not work, it turns out a piece of cheese. I work at Diptrace( https://diptrace.com ), but this problem is not only mine - https://forum.mysensors.org/topic/9528/temperature-and-humidity-sensor-ver-atmega328-e-ink-display/30
