LGS-868
The air quality sensor (LGS-868) analyses room air and summarizes the concentration of mixed gases in the air into a usable value (ppm - parts per million).
Technical information and advice on proper ventilation can be found in the following brochure: Download
Installation
In order to receive data, an IPS-868 gateway (LAN or USB) must first be connected and set up. The parent instances (e.g. the gateway) are created automatically.
Configuration
To use the device in IP-Symcon, a new LGS-868 instance (manufacturer: IP-SymCon/ ProJet) must be added.
If parent instances do not yet exist, they are created automatically.
| Value | Description |
|---|---|
| Device address | The ID:176 is specified by default. If several controllers exist in a system, a new ID must be assigned. The jumper configuration can be found in the operating instructions. |
Only one device with the same ID may be present in one wireless network at a time.
Application
The device returns an integer value that returns the measured ppm (parts per million/ millionth share). The official limits can be found in the table below.
The LGS-868 has 3 LEDs (green/yellow/red), which are automatically switched at the IP-Symcon limit values (450-1000/ 1001-1500/ 1501-2100). The automatic can be switched off by setting “Limit (yellow)” and “Limit (red)” to 0 in the configuration page.
| ppm | Air quality |
|---|---|
| >2100 | Very bad (heavily polluted room air; ventilation required) |
| 2100... 1501 | Bad (heavily polluted room air; ventilation required) |
| 1500... 1001 | Medium (polluted room air; ventilation recommended) |
| 1000... 801 | Satisfactory |
| 800... 601 | Good |
| 600... 450 | Excellent |
Extremely high values above 2100 ppm are rare and are based, for example, on possible alcohols in cleaning products or typical odors in a restroom.
