Vote Now to Support Sustainable Innovation!
Think WIoT | June 2025
We’re proud to share that Dracula Technologies, in collaboration with BLINQY, has been named a finalist for the GEMSTONE Public Award — a prestigious recognition celebrating breakthrough technologies that drive the green transformation of Europe’s manufacturing sector.
Their joint development, the Autonomous BLE Environmental Sensor, stands out as a truly sustainable innovation for the smart building sector. Designed to monitor indoor air quality, temperature, and humidity — all without batteries or cables — the sensor sets a new standard for energy-efficient, maintenance-free IoT solutions.
No Battery. No Charger. Just Light.
The sensor is powered entirely by ambient indoor light, thanks to Dracula Technologies’ LAYER® organic photovoltaic film. Flexible, ultra-thin, and designed for real-world lighting conditions, the film harvests energy even in low-light environments like offices, schools, and warehouses.
Combined with BLINQY’s ultra-low-power software and energy-optimized electronics, the sensor operates 24/7 — all from light alone.
No battery replacements
No USB charging
Reduced e-waste
Reliable indoor monitoring
How It Works
Harvest Light: Dracula’s advanced LAYER® OPV captures light from standard indoor sources.
Store Energy: An ultra-efficient power management chip (by e-peas) and modern storage components optimize energy use and recharge cycles.
Run Smart: Optimized firmware enables continuous data tracking with just 8 hours of daily indoor lighting.
How It Communicates
The sensor includes a visual display for CO₂ levels and transmits temperature and humidity data via Bluetooth® Low Energy. A connected mobile app allows real-time data access and can act as a gateway, enabling automated actions that optimize ventilation and improve air quality.
