OPV-Powered Indoor Monitoring with LoRa Connectivity

Case Studies

Our first OPV-powered indoor monitoring sensor combines low-light energy harvesting with LoRa connectivity, enabling battery-free and maintenance-free operation under indoor lighting. It supports real-time monitoring of temperature, humidity, light intensity, and CO₂ levels for smart buildings, healthy classrooms, and archival environments.

Customer Challenges

As smart buildings, offices, healthcare, and education spaces continue to adopt digital solutions, indoor environmental monitoring devices are being deployed at scale. However, many existing sensors still rely on batteries or external power sources, creating challenges such as:

Limited battery lifetime requiring frequent replacement and maintenance；
High labor costs for large-scale maintenance and inspection；
Complex wiring that limits deployment flexibility；
Battery waste generated over long-term operation, conflicting with sustainability goals。

For long-term IoT deployments, achieving maintenance-free and sustainable power solutions remains a key industry challenge.

Solution Value

ChasingLight, together with Visonic Technology, developed an OPV-powered indoor monitoring sensor that integrates low-light energy harvesting with LoRa wireless communication, enabling self-powered operation, wireless data transmission, and maintenance-free deployment.

The sensor monitors temperature, humidity, light intensity, and CO₂ levels in real time, operating reliably under indoor lighting without built-in batteries or external power sources. Combined with LoRaWAN connectivity, it enables long-range, low-power data transmission for applications including smart buildings, healthy classrooms, archives, and healthcare environments.
