A racing logger for an ND2 Mazda MX-5, integrating wide ranging functionality into one unit:

Complete IoT water quality monitoring ecosystem spanning embedded firmware, LoRa gateways, cloud APIs, mobile/web supervision, and PCB/mechanical design. Features real-time data collection, secure communication, and remote firmware updates.
Eausure measurement node is an open-source printed circuit board by adam-dev-hub, from the adam-dev-hub/eausure-v1 repository on GitHub. It is a 2-layer board of 190 × 95 mm with 53 parts on 65 nets, routed with 450 tracks and 40 vias.
It is built around the DS18B20, INA219AID and BC547, with the BS250 among its other parts. It belongs with the sensors and measurement boards of this library.
Écosystème IoT de surveillance intelligente de la qualité de l'eau s'articule autour de trois composantes principales : une bouée connectée flottante chargée de la collecte des données, une passerelle LoRa développée en interne (DIY) assurant la transmission des mesures, ainsi qu'un environnement logiciel hétérogène regroupant des interfaces utilisateur, des API et une plateforme cloud pour le traitement, le stockage et la visualisation des données.

L'organisation regroupe les différents sous-systèmes de la solution :
EauSûre est conçu comme une plateforme complète, allant du matériel embarqué jusqu'aux interfaces de supervision.
EauSure_Firmware : firmware du nœud de mesure et de la passerelle ;EauSure_User_MobileApp : application mobile terrain ;EauSure_Admin_Dashboard_Website : portail web d'administration ;EauSure_Hardware_API : orchestration matérielle et télémétrie ;EauSure_Admin_API : administration, pré-enregistrement et releases firmware ;EauSure_Auth_API : authentification et identité ;EauSure_Profile_API : profil utilisateur ;EauSure_PCB : conception électronique ;EauSure_3D : conception mécanique.L'objectif d'EauSûre est de proposer une chaîne cohérente de surveillance de la qualité de l'eau, couvrant :

A compact, self-contained development board for the 8051 microcontroller family (AT89x51xxP), designed in KiCad — built to run 8051 firmware on the bench with nothing more than a barrel-jack power supply and a…
It measures 190 × 95 mm and has 2 copper layers, 1.6 mm thick.
53 parts, built around the DS18B20, INA219AID, BC547 and BS250. 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 adam-dev-hub/eausure-v1 repository on GitHub, at the commit this page was made from: the board is EauSure_PCB/source/eausure-measurement-node.kicad_pcb and its schematic EauSure_PCB/source/eausure-measurement-node-full.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 adam-dev-hub before reusing the design.
