Brother-in-law’ wine cellar humidity and temperature supervision
(PART #1)
February 2021
End-to-end project including hardware development up to the cloud-web-application. Humidity, temperature, partial pressure and dew point temperature measures are 
transfered to a bridge-device relaying to the cloud API and eventually into a database; this while WiFi is not accessible, especially from the ceillar (hence the use of 868MHZ transceiver).
An angular Web-App for measures’ history vizualisation and 2 Apps for devices settings: a JAVA/Swing JAR and an Angular Web-App.

The ultimate “raspi-meeting-room project”
May 2020
A meeting-room bookings display based on Raspberry PI Zero W and Waveshare e-Paper 4.2 inch module.
Bookings are retreived in real-time either from Google GSuite (Google API) or Microsoft 365 (Graph API), including push-notifications.
