LoRaUptempo, developed during our studies at UniLaSalle-Amiens, is an end-to-end IoT event-management platform that couples a low-power LoRaWAN device with a modern web application.
The hardware side measures ambient sound levels (dB SPL) and reads NFC/RFID badges; the device then publishes structured uplinks over The Things Network (TTN).
The cloud side—built with Node/Express, MongoDB and React—receives those messages, lets organisers create events, and interactively links each badge/bracelet pair to a registered user profile (CV, social links, etc.). Attendees “badge-in” on-site; organisers approve the association in real time; attendees’ data can be shared instantly and sound-level telemetry is displayed live.
The system therefore demonstrates :
an ultra-low-power LoRa node (STM32 / MKR WAN 1300 + RC522 reader + analogue microphone)
