having a very good idea

Sounds intersting. I am curious …

@leader21

Yes i am from germany. the maximum dimension is 6x8cm.
Now i am also really curious.

will be a surprise, just have a little patience
need some days for preparation but i guess when it’s done it will be awesome

often i get asked about my raspberry cases or sensor enclosures. here a quick hint:
look on ebay for broken devices near to your location.
then you can get e.g. a really pretty playstation 3 case for just 1 euro.

“One man’s trash is another man’s treasure”

now i can disclose the secret
many many thanks to @leader21 he sent me some really cool stickers for my case:

great job @leader21

now i just have to skrew it at the wall.

Nice

WOW!! That looks awesome
Allright guys - who’s next

Looks like an old Auerswald PBX Case

Yes auerswald was written on the case. Do you know what it was? I have no clue

A PBX Phone System - In German “Telefonanlage”

btw. the acronym is PABX for “private automatic branch exchange”

Nice to know. Do you need the board of the phone system?
I just needed the case.

No, I just liked the idea to use this case…

btw: the next step is to integrate a relay to switch off the pump if the water level is low.

Hello Daniel,
hello all,

a gret thread! The Ultrasonic sensor is working on the breadboard and the “Dummy-Dimmer” is also working fine! Hes shows me the filling level of my “Test Cistern”.

Now i want to intall the sensor in the real cistern. There is a empty pipe to the cistern that can be used for the cabel.
The way from the Raspi trough the pipe to the cistern is about 12m…
Thats to long for the ultrasonic to get good data…

I think its the best way to collect the dat with an arduino (in the cistern) and send it to the raspi.
The Hardware setup isn´t the Problem (i hope…), but i have no idea how to collet the data from the arduino and to process it in pimatic???

Any ideas???

Thanks a lot.

Patrick
