Page 5: Installation
Installation Mounting Select the installation place so that the air can flow freely on all sides of the transmitter, representing the air that is to be measured. Avoid heat sources and direct sunlight. Place the device to the measuring location with one of the following ways: •... - Page 6 The Kombi-LWUS works with its default settings and no parameter configuration is normally required. However, if it is necessary to change the settings of the device, it can be done with Nokeval’s MekuWin software (available for free at www.nokeval.com). Following procedure should be followed in order to get access to the settings: •...

Page 7: Operation
Protecting the settings To protect the settings from being easily adjusted, the configuration menu provides a password box. The password can be formed by using up to 16 characters. From the next MekuWin session, the settings cannot be adjusted without knowing the password. If the displayed status is “Locked”, changes will not be saved to the device. - Page 8 Dust13 sensor variants measure PM1, PM2.5 and PM10. The larger Dust40 sensor measures PM1, PM2.5, PM10 and PM40. The sensor does not need periodic recalibration. If it appears to have dust deposited inside, compressed air can be used with extreme care to blow it clean. Monitor menu In MekuWin Mon-menu, the measurement readings can be monitored.

Page 10: Uplink Payload Structure
Uplink payload structure This information is only relevant for integrating the Kombi-LWUS with the customer’s own cloud platform. Consists of several message types, one message per uplink. All values are LSBF unless otherwise specified. Terms: • uint8 = unsigned 8-bit integer •... - Page 11 Type 5 – RH+T+VOC+DP+CO2 measurements Contains first bitflags and then measurement fields based on the bitflags. The bitflags describe which fields are included; if there’s not a bitflag matching the field number, that field is missing from the message, so for example RHT variants will only have T and Rh bitflags and values. Conversion defines the formula to find the measurement result.
- Page 12 Example uplinks Here are some example uplinks to help clarify how the uplink payloads are structured. 050be51d1ce8ff • Type: 05 -> measurements type 5 • Bitflags: 0b = 11 = 1+2+8 = flags 0, 1, 3 -> T, Rh and dP included •...
