Using Thingsee AIR sensor
Thingsee AIR detects carbon dioxide (CO₂), total volatility of organic compounds (TVOC), temperature, humidity and barometric pressure. The product is installed on the wall in the space where air quality is measured.
Thingsee AIR is a perfect tool to measure indoor air quality (IAQ) in buildings and structures, especially as it relates to the health and comfort of the building’s occupants. The sensor ensures real-time air quality data for, e.g. adequate ventilation in the premises.
Thingsee AIR uses event-based messaging where measurement is done every 5 minutes. In case there is a change to the previous measurement, the measured value will be reported immediately. In case the measurement value remains at the same level, it’s reported every 1 hour.
General Installation Instructions
The sensor is for indoor use only. The environment humidity should be <85 % RH at all time. The usage temperature range is +5 ºC to +50 ºC, non-condensing environments only.
Please note that the correct TVOC and CO₂ data are available only after the sensor device has conducted baseline calibration for the environment.
- TVOC sensor conducts baseline calibration for the TVOC levels and valid data is available after 24h of continuous use.
- Accurate CO₂ baseline level is set by auto-calibration during the first 8 days of usage. The auto-calibration is based on the outdoor CO₂ level. CO₂ level in normal air pressure is 400 ppm.
Note: Thingsee AIR requires ‘free of people’ moments in the space, when the indoor air is fully changed, to set the correct 400 ppm baseline. This is why places such as schools and offices are good places to use the sensor, as the baseline can be set during the night.
Note before installation
Please make sure the Thingsee GATEWAY is installed before you install the sensor.
To ensure strong enough signal strength for data delivery, keep the maximum distance between installed sensors under 20 m.
If the distance between a measuring sensor and the gateway is > 20 m or if the sensors are separated by a fire door or other thick building materials, use extra sensors as routers to ensure adequate signal strength.
Things to avoid in installation
Avoid installing Thingsee products near the following:
- Thick concrete structures or thick fire doors
- Electrical transformers or thick electrical wires
- Nearby heating or cooling devices and/or vents
- Direct sun light
- Nearby halogen lamps, fluorescent lamps or similar lamps with hot surface
- Nearby radio equipment like WiFi routers or any other similar high power RF transmitters.
- Avoid installing the sensor in close proximity to a spot where there’s people presence constantly, such as right next to workstations.
Please make sure the Thingsee gateway device is installed before you install the sensors.
To identify the sensor, read the QR code on the side of the A-cover with a QR code reader or Thingsee installation application on your mobile device.
Identifying the device is not necessary, but it will help you keep track of your IoT installation and help Haltian support to solve possible issues.
Open the box and follow the instructions of this user and installation guide. Take the product from the box and open it with the opening key.
Select a place where to install Thingsee AIR (see ‘Things to avoid in installation’ before). The recommended height on the wall is between 1,4 m – 1,8 m.
When holding the sensor in hand: Place the opening key in the hole on the side of the sensor and twist to open.
When the sensor is on the installed surface:
Installing Thingsee AIR with a screw
Take the B-cover and place it on the wall on the decided location. Screw the B-cover to the wall (use anchor with concrete wall or gypsum board).
Place the batteries inside the A-cover.
If you change the batteries, Haltian recommends using Varta Industrial Pro 1.5 V AA LR06 alkaline batteries.
Attach the A-cover to the B-cover attached to the wall. (Make sure the Thingsee logo is the right way).
Note: Make sure the sensor is installed max. 20 meters from the next sensor or gateway. This is to ensure full coverage mesh network between the sensors and the gateway.
Installing Thingsee AIR with tapes
When installing Thingsee AIR using tapes, use a smooth surface for better adherence.
Clean the surface you will attach the sensor to with IPA -solvent (isopropyl alcohol).
Make sure that the surface of the device is clean.
The marks in the back of the sensor work as guidelines for where to place the tapes. Apply the tapes in the device and press for a minimum of 5 seconds and then remove the tapes’ paper cover.
Attach the sensor to its place by pushing it firmly against the surface for a minimum of 5 seconds.
