SMTBCNEU868

The TEKTELIC BREEZE (SMTBCNEU868) is a compact LoRaWAN indoor air quality sensor that monitors CO₂, temperature, humidity, ambient light, and barometric pressure in a single device. Built around an NDIR CO₂ sensor with self-calibration (configurable, default every 7 days) and integrated barometric pressure compensation, BREEZE delivers high accuracy across deployment altitudes. The compact 80 × 80 × 30 mm enclosure mounts on walls, ceilings, or tables and pairs optionally via Bluetooth Low Energy with the TEKTELIC E-Ink Display for at-a-glance real-time readings at a convenient viewing location. Powered by 2× AA LTC batteries for 10 years of operation. LoRaWAN Class A radio operates at 15 dBm with −137 dBm sensitivity. Ideal for smart homes, offices, schools, retail, and public buildings.
