We offer you a guide for making your own carbon-dioxide sensor unit to measure the percentage of carbon dioxide gas.
You get the necessary circuit board from us for free!
You only need to buy the sensor, a few cheap electronics parts, a cheap Multi-Function-Shield, and the Arduino.
The purchase sources and article descriptions can be found in the assembly instructions.
With the help of the manual, a soldering iron and some skill you can build your own CO2 sensor.
Please note: This offer is limited to one board per order and valid until our stock lasts. Not for resale, no warranty, no legal claim for delivery.
