TR9277 uses EnOcean Profile (EEP) A5-09-04 for CO2 Temp and RH.
RTH units have options for Temp, Temp+ RH, Temperature Adjust, Occupancy Reset and use corresponding EnOcean EEPs. See datasheet.
“Zero Energy” Transmitter that harvests power from ambient light.
Integrated CO2 self-calibration feature eliminates maintenance.
Built-in absolute pressure sensor corrects CO2 reading for altitude.
Utilizes the open, EnOcean® wireless protocol that is designed for integration with other products and systems (ISO/IEC 14543-3-10).
Provides feedback on local light strength, and radio signal during installation to facilitate optimum placement.
Can be easily calibrated in ambient air to support a seamless commissioning process.
Optional battery can be installed to provide extended backup in low light conditions. Five year operation on button battery alone.
Smart power management logic manages sampling and message transmission based on real time ambient light levels.
Current CO2 level can be read at any time bypressing button and counting LED flashes.
The TR4300 family of EnOcean product offers the ability to measure temperature and humidity in an enclosure with functional operation similar to the TR9277-EO. The datasheet below provides details on options available.
The CO2 Guard 10 reliably shows the carbon dioxide (CO2) concentration in the ambient air as a measure for indoor air quality (IAQ). The CO2 level indicated by the LEDs helps deciding on the need for ventilation, for example by opening the windows.
The Sigma 05 sensor hub represents the central element of the E+E modular sensor ecosystem with intelligent probes, analogue outputs and display. With pluggable, interchangeable probes, the modular sensor platform is suitable even for harsh and challenging environment.
The TR9277-EO is a light harvesting, EnOcean® wireless transmitter, that measures CO2, Temperature and Relative Humidity in an attractive wall mount enclosure. The sensor is powered by ambient indoor light. The CO2 concentration in the space is indicated by pressing a side button and watching the flash sequence of LEDs on the right side of the light-harvesting panel.
3-in-1 sensor module measures Carbon Dioxide (CO2), Temperature, and Barometric Pressure. Low power consumption makes it suitable for battery-operated devices such as hand-held meters, data loggers or wireless transmitters.
