Step 2
Prepare the hat
- Place the filter with the pink side up into the hat.
- Insert the filter holder in the hat. Start with one of the short sides, and align the pins on the filter holder with the holes in the hat.
- Now push the filter holder in all the way.
- You should hear a click when it snaps into place on all sides.
Place the filter with the pink side up into the hat.
Insert the filter holder in the hat. Start with one of the short sides, and align the pins on the filter holder with the holes in the hat.
Now push the filter holder in all the way.
You should hear a click when it snaps into place on all sides.
Step 3
Prepare the PCB
- Snap off the two thin strips of the PCB on each side
- Add after phhoto

Step 4
Connect the CO2 sensor wires
- Ensure that the ports of the connectors are open before inserting the wires.
- Open
- Closed
- Attach the wires of the CO2 sensor in the same way as in the photo.
- Pull on all the wires carefully to make sure they are properly connected and will not release.

Step 5
Secure the CO2 senor to the PCB
- Twist the CO2 sensor one time so the wires are not loose.
- The blue and green wire should be on the outside of the PCB.
- Use a zip tie to secure the CO2 sensor the the top of the PCB.
- The sensor should not stick out past the PCB.

Step 6
Insert the battery
- Place a small piece of plastic from a filter on the negative side of the battery holder.
- The negative side is marked with (-) and is on the side towards the solar panels.
- Insert the battery with the correct orientation into the battery holder.
- Pay attention that the plus (+) and minus (-) on the battery and on the PCB are on the same side.
- Secure the battery with a zip tie.
- The zip tie is inserted from the front, just below the “sigrow” text and goes around the battery and through the PCB again.
- The zip tie is then sequred with another zip tie.
- Cut off the remaining parts of the zip tie.

Step 7
Prepare the case
- The PCB plate should be inserted into the case in the same orientation as the photo.
- Hold the case such that the Sigrow logo is towards you.
- The PCB plate should be inserted such that the rectangular hole is slightly to the left.
- The smallest hole should be on the right side towards you.
- The PCB plate should be pushed in all the way and pressed against the fins sticking out of the case.
- Finished photo missing

Step 8
Final assembly
- Insert the PCB so that the CO2 sensor is on the side of the Sigrow logo.
- The PCB should be pressed against the PCB plate.
- The antenna should now stick out less than 5 mm.
- Slide the hat over the case. The hat should fit well and not come lose if you shake the senor hard.
