      @fred Normalement le code dans l'Arduino (donc ça doit marcher sur Nano) ne fait que transmettre les informations. Tu parles de quel code ? quel sketch tu mets dans ton Arduino?

      @cbparks The reading and display depends on reference resistors soldered on your boards, in my design it's 390 for PT100 and 3900 for PT100, it's declared here and the only place it should be Then declare if you want to use PT100 or PT1000 here

      Zydog, Thank you for you comment. Building removing all power consuming elements is one of the keys. For low power you cal remove all regulators and DC power converters if any. Powering with 2 AA/AAA provide 3V which can be fine, but take space The DHT11 is not the best sensor since it's slow and consuming power during conversion but with 2 AA/AAA it should works quite long as soon as you disable the sensor during low power sleeping mode. For ULPNode I'm working also on Gateway, currently an Arduino like but still testing with Spark Core / now particle and even ESP8266, they have more flash/ram add allow the gateway to do some other things such as displaying on a LCD/OLED

      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. [image: wTe37Sj.png]

      @cdmsjtr Sorry for my late response, I'm still working on it, the card is not in production yet, I need to finalize small things. Charles

      Dear Charles, I wonder how this story ended. It sounds impressive and just like the kind of board I am looking for. Can you give an update?

      Guys, Humm, that's interesting, I already fixed a problem with negative values in library (see ). As far As I remember this fixed the problem (but may be it's another issue now) Are you using the latest version ?

      @schoopy I looked at the schematics and it not possible "as is" but you can do it of course. If your power is 5V I suggest you bypass the ArduiPi Regulator and send 5V to Pi using a wire like as follow [image: 1451775761832-arduipi-power-5v.png]
