Duct air quality sensor LK+ LoRaWAN

CO2VOCrelative humidity

The maintenance-free and multi-functional duct air quality sensor measures CO2, mixed gas (VOC), temperature and humidity. A hinged cover and tool-free wiring as well as removable cable entries ensure a quick and easy installation. In addition to LoRaWAN®, additional analog voltage outputs are available as interfaces. In radio-shielded mounting locations, an optional external antenna can be used to optimize the radio link between the device and the gateway. • Application/type : Duct sensor • Purpose : Measure values • Measured values : temperature, relative humidity, CO2, VOC • Interface : LoRaWAN® (868 MHz), Active, 0..5 V, 0..10 V • Configuration : USEapp, uConfig, jumper, LoRaWAN® Downlink, each output can be set to get a variable mix of CO2 and VOC by configuration via app or uConfig • Sensor : NDIR (non-dispersive, infrared) • Output voltage : 2x 0..10 V or 0..5 V, adjustable via jumper, live-zero configuration via app or uConfig, min. load 10 kΩ • Radio technology : LoRaWAN® (868 MHz) • Data transmission : bidirectional • Operating range temperature (°C) : 0..+50 • Output signal temperature : scaling analogue output, 0..+50 °C (default setting), selectable from 4 temperature ranges -40..+60 | 0..+50 | -20..+80 | -15..+35 °C, optionally configurable • Operating range humidity : max. 85% rH short term condensation • Accuracy temperature : ±0,4 K (typ. at 21 °C), ±0,5 K (typ. at 21 °C), within default measuring range, offset setting via app or uConfig • Measuring range humidity : 0..100% rH non-condensing, 0..85 KJ/kg enthalpy, 0..50 | 0..80 g/m³ absolute humidity, 0..+50 | -20..+80 °C dew point, optionally configurable
