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.
-
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.
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.
