Because the used SGP40 and the LED needs current there is no battery powering planned.
I find the RAKBox-B3 a very good indoor solution but some more room could be helpful. Is there an alternative where IO modules find the needed additional place?
Your project looks interesting. Your #1 point is valid - RAK11200 extends beyond the board (your work-around seems to be fine though). With #2, maybe a straight USB C cable might consume less space?
We have in the pipeline indoor enclosures too (no date of release yet) but for now, the outdoor ones is the only option in store. These enclosures are designed to work in WisBlock and comes in different sizes. Also, it has WisBlock compatible baseplate. Custom holes can be made as well (with additional cost). Maybe you can have a look

Thank you for sharing here. Interesting article.
Btw, regarding the temperatures shown in my image, I am in the Philippines, so 29 deg C is quite cold.
@ckuehnel Great Article! I was looking for a solution to measure indoor air CO2 myself and I like your IR work around. Iām currently in the process of building a Corsi-Rosenthal box with PWM computer fans. I was thinking of using wisblock to measure CO2, particles or whatever air indicator really, and then have a control loop that speeds up the fans until the air cleans up.
