Greatech Launches CO₂ Sensor with Multi-Connectivity, Featuring Epishine Indoor Solar Cells and e-peas’ Power Management

Greatech, a German hardware developer and manufacturer specializing in energy-efficient wireless embedded systems for terrestrial and satellite communication, launches Sensoco® Loomair Solar, a light-powered CO₂ sensor with multi-connectivity designed for smart buildings. The sensor combines Epishine’s indoor solar cell as the power source with e-peas®’ power management integrated circuit (PMIC), ensuring efficient energy conversion and continuous operation. Developed for smart buildings, Sensoco® Loomair Solar is now available as a sustainable, cost-effective, and maintenance-free IoT solution. 

As the number of industrial IoT devices required for smart buildings grows, so does the pressure to move away from disposable batteries. This shift is driven by stricter battery regulations and by the need to reduce Total Cost of Ownership (TCO). Energy-harvesting offers a credible and sustainable alternative to disposable batteries. To address this critical need, Greatech, e-peas, and Epishine have joined forces to launch Sensoco® Loomair Solar, a light-powered CO₂ sensor with multi-connectivity. This innovative sensor is powered solely by Epishine® indoor solar cells capturing energy from indoor light. 

Greatech’s Sensoco® Loomair Solar: A light-powered CO₂ sensor with multi-connectivity designed for smart buildings.

Christoph Grundig, Co-Founder of Greatech, remarked, “This sensor is a testament to the possibilities of highly efficient energy harvesting, enabling us to meet sustainability goals without compromising functionality or design. Design and assembly are made at our facility”  

As smart buildings increasingly rely on advanced connectivity and efficient solutions to unlock their full potential, Sensoco® Loomair Solar stands out as a key innovation, offering wireless functionality powered by light. The sensor supports multiple communication protocols, including Mioty®, Wireless M-Bus, LoRa or Sigfox®, ensuring seamless integration into existing systems. This flexibility allows property owners to choose the solution that best fits their needs without the need to replace their current Building Management System (BMS).

“Our PMICs offer industry-leading energy conversion efficiency, enabling the sensor to support multiple communication protocols. This ensures seamless integration, reliability, and efficiency in interconnecting PV cells, applications and storage elements, critical to a building ecosystem”, said Bruno Damien, Ecosystem & Partners Marketing Director at e-peas. 

“This launch exemplifies the progress in smart building technology, combining indoor solar cell innovation with seamless connectivity to deliver a sustainable, maintenance-free solution,” said Niklas Forsgren, FAE Director at Epishine. 

Sensoco® Loomair Solar is now available to order directly from Greatech. Visit Embedded World 2025 at e-peas’ booth (#4A-301) and Mioty Days to see the product and discover how it can transform your smart building operations. For more information or deployment inquiries, please contact us.
