Sensors-1

Miniature CO2 sensor module with NDIR technique
  • NOTE:
    ESD-sensitive product.
    Use ESD protection equipment.

  • NOTE:
    Handle sensor by holding PCB only.
    Never touch sensor with bare hands! Use clean gloves to avoid dust, grease or other contaminations.
    OBA shall not be subjected to any force.SenseAir S8 Carbon Dioxide Infrared
CO2 Sensors-2

  • NOTE:
    To ensure airflow, and quick sensor response time to changes in the environment: do not block particle filter!

  • NOTE:
    No gluing or molding on OBA.

Installation and soldering

See IPC-J-STD-001 for acceptable soldering conditions in general.
Selective soldering machine (drag soldering method): soldering temperature 295°C during three seconds. Hand soldering: soldering iron temperature 380°C during two seconds/pin.
Mechanical properties
Please refer to mechanical drawing of detailed specification regarding dimensions and tolerances.
Layout considerations:
Use cut-outs or slits in main board to reduce mechanical stress to sensor due to board thermal expansion. To ensure stability, do install pin headers on both sides of sensor.SenseAir S8 Carbon Dioxide Infrared CO2

Storage

Storage in sealed ESD bags. Storage temperature: -40 – 70°C Requirements on storage environment: in normal IAQ environments corrosive environments are excluded.

Inspection – verification

Transport, handling or assembly may affect calibration. A host system counts ABC (Automatic Baseline Correction) period itself and has to write ABC command to the “Calculation Control byte” when ABC period (8 days) expires. Contact Senseair for further information! Inspect and perform zero calibration after transport.
