SM03E02ACC is an Eelectron sensing product or sensor accessory for building automation. Depending on the specific model, this family may provide occupancy/presence detection, temperature, relative humidity, air-quality measurements, weather measurements or an auxiliary probe input. KNX sensor products typically transmit measured values and/or occupancy states to the bus for use by lighting, HVAC and energy-management functions. The exact sensing elements, measurement range, detection geometry, mounting arrangement, bus current and environmental protection are model-specific. These values are left unfilled unless supported by a matching manufacturer datasheet, rather than being extrapolated from a neighbouring model. Confirm the precise variant and ETS application before specification.
