Overview
The NOVOS 3 SR wireless room sensor provides precise measurement of CO₂ concentration, temperature, and humidity using EnOcean radio technology for energy-efficient building automation. Designed for residential, office, and commercial spaces, it operates primarily on harvested solar energy, with an integrated supercapacitor and optional 3.6 V lithium battery for low-light environments. Data is transmitted unidirectionally to compatible receivers or gateways for further processing. Featuring an elegant flat design, adhesive or screw mounting, and secure CRC8 or encrypted transmission, the NOVOS 3 SR ensures reliable performance and easy integration into modern EnOcean-based BMS networks, improving indoor air quality and comfort.
CO₂ measurement range: 0–2550 ppm (NDIR LED-based sensor). Annual recalibration recommended for humidity sensor accuracy. CO₂ sensor supports ABC Logic for automatic baseline calibration (optional). Typical battery life: 2 years under normal light conditions. Accessories: adhesive foil (included), optional screws and wall plugs. Compliant with EN 60529 (IP20 protection class).
