This case well for those who are reluctant to touch the naked CO2 Sensor Evaluation Kit SEK-SCD41 - Sensirion. Complies in a realistic range with the Design-in Guide SCD4x CO2 Sensor provided by Sensirion, but not suitable for situations where accuracy required. And equips the refracted slit to get both shading and ventilation. Thing to note is that you will also need 4 sets of screws and nuts.

Other necessaries:

• 4 sets of M2.6x10mm screws, head diameter < 3.7mm
• 4 sets of M2.6x4.5mm nuts, thick < 2mm
