Summary

It supports the following:

• AM312 motion sensor
• BH1750 light sensor
• SHT31-D temperature and humidity sensor

Features

• USB charger can be rotated to accommodate different outlet orientations
• Small PIR motion sensor housing can be angled toward area of interest
• Ventilation added to improve temperature and humidity readings. I didn't have good luck with the BME280. I still needed to calibrate the SHT31 so it isn't perfect.
• Small wiring access port for future expansion
• Snap-fit enclosure design
• Minimal size won't block the other outlet

Design Details

The case size could be reduced by sourcing a smaller charger. 1A is sufficient for the D1 Mini.

To keep the cover as short as possible, I created my own USB cable using the following solder jacks:

Used 30AWG flexible silicone wire as the space gets used up quickly: https://www.amazon.com/gp/product/B01KQ2JNLI
