Light-Powered CO₂ Sensor For Smart Buildings

The sensor operates without batteries and supports multiple communication protocols, ensuring seamless integration into existing systems. 

Greatech, a German developer and manufacturer of wireless embedded systems for terrestrial and satellite communication, has launched Sensoco Loomair Solar, a light-powered CO₂ sensor with multi-connectivity designed for smart buildings. The sensor integrates Epishine’s indoor solar cell as the power source and e-peas’ power management integrated circuit (PMIC) for energy conversion and continuous operation.

As the demand for industrial IoT devices in smart buildings increases, the need to move away from disposable batteries grows due to regulatory changes and cost concerns. Energy harvesting offers an alternative by reducing reliance on batteries. To address this need, Greatech, e-peas, and Epishine collaborated to develop Sensoco® Loomair Solar, which operates using indoor solar cells that capture ambient light.

It supports multiple communication protocols, including Mioty, Wireless M-Bus, LoRa, and Sigfox, ensuring compatibility with various building management systems. This allows property owners to integrate the sensor into existing infrastructure without requiring system replacements.It is now available for order directly from the company. 

Bruno Damien, Ecosystem & Partners Marketing Director at e-peas, commented, “Our PMICs provide high energy conversion efficiency, enabling the sensor to support different communication protocols while maintaining reliability.”Christoph Grundig, Co-Founder of Greatech, stated, “This sensor demonstrates the capabilities of energy harvesting, allowing us to meet sustainability targets while maintaining functionality. Design and assembly take place at our facility.” Niklas Forsgren, FAE Director at Epishine, added, “This launch highlights advancements in smart building technology, combining indoor solar cell efficiency with reliable connectivity.”
