Hello rozpruwacz, Thank you for your comment. This idea seems quite interesting for me and certainly I will look into it in the future. But for now you need to know the best way to power up this modules is by using one PSU for the whole bus. It is very important to have common GND on every module on the bus. To do this you will need 4 wires though.

@aze No Problem all the time nice to hear idea from people

@anticimex You are too fast Now the CERN files are uploaded!!

Hello, interesting project. I am looking for some relays 10A, but i do not find under 5VDC. Where did you buy them ?

Hi, Is this a finished solution? Just plug the 2 aaa batteries and play? Or do i need to solder everything my self? Also the magnet reeds you talk about are these those one? https://cdn.sparkfun.com//assets/parts/1/0/4/4/0/13247-01.jpg How to connect? Thank you

@sundberg84 - ok thanks, it makes sense ;). I was asking because I connected your Dimmable Led Strip daughterboard via MysX to this Easy PCB. Dimmer daughterboard is providing 5V on PIN3 (when LM2940CT voltage regulator is used on it). This would bring 5V to output of voltage regulator on Easy PCB so I disconnected PIN3 connection between dimmer daughterboard and Easy PCB. I connected PIN3 from dimmer board by wire to >3.3V power input of Easy PCB instead. Other option I'm thinking of would be not using voltage regulator on dimmer daughterboard at all but use its 12V raw voltage provided by dimmer board via MysX PIN1 (+ raw jumper on Easy PSB) and use voltage regulator (LE33) on Easy PCB only.

@schif Hello, Thanx for you comment. Yes you can use it but use a ceramic capacitor

the message sending time was reduced to 10 seconds as in the debug mode. There is no difference in the dry sensor or in the water.

Hi @koresh - I had a little accident on the AC side :-). I was wondering what values the 2 resistors (TH and SMD) and diode are ? Thanks!

@koresh Package went under the "Postnord" radar! Woohoo, perfect! I will start replacing the old capacitors and finally be able to deploy the sensors. Very nice of you to include some product samples as well. Really excited about these sensors!

@gohan Yes, you are right, this is done by cnc router.

@GertSanders ok, strange. standard pin headers fit for me only into FTDI and ICSP pin holes. Into the other two 8 pin rows it does not fit.

@yoonie said: For the pro mini version, should i create another Openhardware project, or should i put it here, in the already existing project? Might be better to create a new project as they uses a different set of design files.

this kind of optic fiber is probably only plastic so for a full DIY , you can use also fishing wire with a big power led or an old chistmass tree optic fiber lighted.....

@zeblong, you can generate these from the board files, however i'm leaving this one for @Ivan-Z to discuss with you as this is his device and he knows all details regarding this.
