The Neutrino temperature, humidity, and pressure sensor has had some heavy modifications over the last few weeks. Most notably, I’ve given it the option of installing an nRF24L01+ module onboard while still providing the header for an external board. We’ve also got jumpers to select the channel, address, and encryption. It has also grown a reed switch, for use as a door/window open sensor. The Arduino library for the SI7021 pressure and humidity module has been written, and hosted on github here.
Work has commenced on the web UI, and while there’s work to do yet, this has allowed me to also flesh out the API and database. Here is a screenshot of the per-sensor and sensor group views.
