💬 Button size radionode with sensors swarm extension
-
@gohan I only have a normal multimeter - what's the best way to do this?
I came across https://www.eevblog.com/projects/ucurrent/ a while ago, is it worth it?@chbla said in 💬 Button size radionode with sensors swarm extension:

You should be fine even with a cheap multi-meter as long as it has uA scale.
should be around 7-10 uA and if you do not send JDEC to sleep it is 17 -19 uA.
to send JDEC to sleep\wakeup I use
_flash.wakeup();
_flash.sleep();light sensor should be sent to sleep explicitly also.

@yury not really, I have bought an Aneng cheap multimeter, but if I connect it with uA scale selected it will go out of range during node boot and cut the circuit making measurement impossible (unless you do something fancy that would make it unpractical)

my cheap one survives 20mA surge (RFM69 CW version) of initial communications and displays good reading afterwards. if you burned fuse inside, try replacing it temporarily with some thin wire for this uA tests.

Right - but this is all in your sketch right? This is what I used:

I downloaded gerber files.
Error Message from PCB Manufacturer:
The NC drill layer does not match with the pads of copper layer.Thank you,

Finally I have a little time to continue this project...
High efficient dc-dc converter works nice and double cr2032 are good. Lets go to the furher tests! :face_with_cowboy_hat:
-
New version with double battery holder and power convertor works nice.
Power consumption in sleep mode is less than 9uA :smiley:
I will test it soon..

Which pcb manufacturer do you recommend?
I asked for a quote from Pcbway but it was expensive.
The reason was:
Change the 'Min Track / Spacing' value from 6 / 6mil to 5 / 5mil.Sorry for my bad English.
-
10 would be needed for the current project
At pcbway, the total cost of production and shipping costs is $ 34.
Is there someone who does it at a lower price?
Business account required.I apologize for asking this question in this topic.
What type of transformer do you use and where to get it for the Mini Relay Box? -

Yesterday I ordered 2 plain PCB's from seeedstudios, cost me 20 dollars incl, shipping. paid more for shipping than for the PCB's themselves. :)
but for the size, these units are you can get 6 or more in one design.
