@scalz water temperature ? For baby bath ? I'll check if it work with my next coffee. Let me find my ir sensor.

For science !

ps: yes it's working

@Nicklas-Starkel last weekend one of my sensors broke. Both pins were completely corroded and broke

Did you try to just paint the sensors ?
I've seen that here: https://www.tindie.com/products/miceuz/i2c-soil-moisture-sensor/

It doesn't work for me. I go double check the wiring. EDIT: not it's okay now. Great !

But is it possible to use A0-A1, A2-A3, A4-A5 on a atmega328P or there is the same pullup problem ?

I'm asking myself: does an ATMEGA could have a footprint smaller than the arduino nano board ?
For MySensors sketchs I mean. Because we can easily work with 8Mhz, and so, only need 4 composants:

• ATMEGA328P-PU
• 10kohm resistor
• 0.1µF capacitor
• 0.1µF capactior
  With that, a power supply between 2 and 3.3Vcc (because of the NRF, the ATMEGA can handle 5Vcc).

And we have more interrupt pin to play with. It seem to me that it may be an cool alternative design non ?

What do you think ?

Hello everyone,
I would like to make a repeater with tow radio, because my gateway is 2.4Ghz, but i wan't to put outdoor sensors in 433Mhz.

BUT: as i'm not english native, i may haven't found the keyword to find this kind of project into the forum, is there anything like this ?

Thanks, and have a good day !

I've got one for my 3d printer so:
3d printer safety control ! Because we should be next when printing, but we can't.
