SMTBMDEU868

The TEKTELIC BREEZE-V with Display (SMTBMDEU868) bundles the LoRaWAN CO₂ and occupancy sensor with the TEKTELIC E-Ink Display for at-a-glance real-time readings. The sensor combines NDIR CO₂ measurement with PIR-based occupancy detection, ambient temperature, humidity, light, and barometric pressure sensing in a compact 80 × 80 × 30 mm enclosure. The CO₂ sensor self-calibrates every 7 days and uses barometric compensation for accurate readings at any altitude. The PIR sensor supports interchangeable masking for tailored fields of view. The included E-Ink Display pairs via Bluetooth Low Energy and can be placed at a convenient viewing location while the sensor stays optimally placed for measurement. Powered by 2× AA LTC batteries for 9 years of operation. LoRaWAN Class A radio operates at 15 dBm with −137 dBm sensitivity.
