Hi all, Should anyone face the same problem, I found the root cause: brownout threshold. I burned a new bootloader (Optiboot 8.0) without such trigger and the node has been working with used batteries (~2.7V) since May. Hope this helps.

@Nca78 said in Particle Powered Air Quality Sensor Logging to Google Docs: @Sebex said in Particle Powered Air Quality Sensor Logging to Google Docs: Perhaps I don't necessarily need to use the same pins Both the sensors you quote are using I2C. So they both use the same 2 pins (SDA, SCL) to communicate. You can put many I2C sensors on those same pins, they each have an address to know which sensor is receiving/sending data to the master (here, your arduino). Look for a tutorial on I2C first. Thanks I get it now

@canossa Sorry for the late response. yeah, since is so compact and you can get it for relatively cheap I opted in for the NRF52. For home automation, I merged MySensors with Domoticz and it works for months now. https://forum.mysensors.org/topic/7836/what-did-you-build-today-pictures/738

Please Is it possible to buy only PCB? Do you plan also to release your sketch?
