Ceiling Module | High Endurance Micro-SDHC card 32 GB 100 MB/s UHS Class 3 by SANDISK

This card is used for Raspberry Pi operating system. Because we collect a lot of data which we are going to store in InfluxDB we have a huge amount of writing cycles. In the past we tested out regular SD cards which were defect after approx. one year of life time. So instead we use a "high endurance" or "industrial grade" SD card. Please do NOT remove the sd card with tweezers. You might scratch it to death, like shown in the following photo:
