crnicholson/Plant-Monitor2Plant Monitor is a way to view data from a remote humidity sensor on web interface, which then tells you when you need to water your plants plus the air humidity, soil humidity, air temp, and air pressure.
PlantMonitor is an open-source printed circuit board by crnicholson, from the crnicholson/Plant-Monitor repository on GitHub. It is a 2-layer board of 35.5 × 126 mm with 50 parts on 47 nets, routed with 695 tracks and 134 vias.
It is built around the ATMEGA328P-AU, RA-01 and BME280, with the MCL103A-TR among its other parts. Its parts include 17 capacitors, 12 resistors, 4 ICs, 4 switches and 3 connectors. It belongs with the AVR (ATmega, ATtiny) boards of this library.

Plant Monitor is a way to view data from a remote humidity sensor on web interface, which then tells you when you need to water your plants plus the air humidity, soil humidity, air temp, and air pressure. These metrics can be combined with AI to predict forest fires.
Plant Monitor uses Auth0 to securely log into the web interface. No data or passwords is shown to me.

crnicholson/StratoSoar-MK2
StratoSoar is an engineering project that aims to be able to fly a glider (dropped from a high-altitude balloon), down to any selected coordinates.
It measures 35.5 × 126 mm and has 2 copper layers, 1.6 mm thick.
50 parts, built around the ATMEGA328P-AU, RA-01, BME280 and MCL103A-TR. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the crnicholson/Plant-Monitor repository on GitHub, at the commit this page was made from: the board is PCB + Schematic/plantMonitor/plantMonitor.kicad_pcb and its schematic PCB + Schematic/groundMonitor/groundMonitor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask crnicholson before reusing the design.
