Live Demonstration: Energy Autonomous Wireless Sensor Node for Oxygen Monitoring with LoRa Connectivity

Year: 2025

Type: conference-paper

Abstract: This demo presents an innovative wireless sensor platform for oxygen monitoring, featuring LoRa connectivity and a unique battery-free operation to ensure maintenance-free usage. The platform integrates an advanced oxygen sensor and leverages LoRa technology to transmit data efficiently over long distances. Powered by a photovoltaic cell, the system is independent of conventional batteries, eliminating the need for periodic replacements. The photovoltaic cell supplies energy for the sensor’s operation and charges a 1F supercapacitor, ensuring continuous operation without light. The 1F supercapacitor allows the system to acquire data from the oxygen sensor and transmit it via LoRa connectivity with a configured spreading factor of 7 every 10 minutes for up to 10 hours without light.
