![CDATA[The KNX wall/ceiling sensor Sewi offers various variants with brightness, presence, temperature, humidity, CO2 and pressure sensors. With multifunctional modules and logic gates, it records indoor data and controls limit-dependent switching outputs. The sensors enable states to be linked via AND and OR logic gates. Multifunctional modules change input data as required. CO2 and humidity sensors have an integrated PI controller for ventilation control, temperature sensors for heating/cooling. Product features include brightness measurement, motion detection, temperature and humidity measurement with mixed value calculation. Technical data: plastic housing, surface mounting, IP30, dimensions approx. Ø 105 mm x 32 mm height, operation via KNX bus voltage, max. 10 mA bus current. Specifications of the sensors: Temperature measuring range 0 - +50 °C, humidity measuring range 0% - 95% RH, brightness measuring range 0 - 150,000 lux.]]>
