Control CO2 Construction kit
(CO2, temperature and relative humidity sensor)
€56,02 VAT excl.€67,79 incl. VAT)
Make your own CO2, temperature and relative humidity sensor.
Build your own CO2 sensor V2
New in version 2: temperature and relative humidity sensors, NDIR CO2 sensor with a range of 400 to 5000 ppm (instead of 400 to 2000 ppm in the previous version).
This kit contains a blue printed circuit board (PCB), NDIR CO2 sensor, temperature and relative humidity sensor, display board and all necessary connectors.
All you need is a soldering iron, solder, some time and enthusiasm.
This kit does not include a USB-C cable or USB adapter. If necessary, you must order these separately.
If you want us to solder the kit beforehand, order the Assembly Add-on (1 per kit), so you don't have any extra work.
You can 3D print a housing yourself.
You can put the software on the board yourself, here is the code.
PS: there is also a version without temperature and humidity sensor. This one is cheaper and can be here find.
Are you interested in a CO2 STEM teaching package? Then order your CO2 meter(s) and STEM bundle via TESS!
Leave the CO2 sensor on continuously, the first 1 to 8 days after start-up it will do a self-calibration and the values may not be correct. At least once a week (and better every day) the sensor needs to "see" at least 1 hour of fresh outside air to be able to recalibrate itself every week. So ventilate your room every day!
P.S.: Commercially available CO2 meters with a real NDIR CO2 sensor often cost more than 150 to 250 euros. This open-source project has been able to count on the efforts of the Makers-community, which enabled us to keep the price as low as possible, for a real NDIR sensor. In the same price range on the commercial market you will only find worthless VOC sensors, or fake NDIR.
