I am of the opinion that the slightly larger enclosure is best because it gives the end-user the opportunity to modify and expand the array of sensors while maintaining a clean and compact form factor.
Hello,
I have finaly build (recreated) what Charles showed...
I have one problem now. How to turn MCP for the first time battery is inserted.
Can someone show me how he did it?
My schema looks like this and is EN by low state from voltage supervisor.

Hello @Charles
I hope you have a chance to take a look on ULPnode schematics. Do you have any progress on this topic? Any chance to see raw materials or at least photos or schematics?
Hi Charles,
It's a very interesting project, I'd very much like to get my hands on a few of them.
Do you have any idea how these nodes will hold up in a situation with reinforced concrete?
Cheers,
Stefan.
Charles,
I ran into th website souliss it seems to be a Arduino library with protocol definitions and interactions between nodes via various radio's. There an API and APP to control. Looks a good solution to integrate te ULP-Node into the world of things. No Central site.
No Gateway if you want to. All operational (even for ESP unfortunately no SPARK.
Greeting Koen.
Jazbond,
non c'est pas super compliqué mais il faut aussi ensuite pouvoir les positionner sur le PCB, or le NRF24 il faudrait la version SMD pour pouvoir le souder dessous.
Je pensais aussi faire une version ESP8266 en lieu et place du Photon/Spark mais j'ai pas eu le temps pour le moment.
