Sensor Sphere Box

thingiverse

I'm building a custom sphere box to create my own smart home system that looks sleek and modern. I've opted for using an 18650 battery to power the Arduino code on either a Wemos or NodeMCU board inside the sphere. There's also space for a micro USB port to charge the battery via a small charger I ordered from AliExpress. Currently, this sensor box (sphere) transmits temperature and humidity data to a cloud server every 20 minutes before going into sleep mode. I'm actively working on reducing power consumption so that it doesn't drain the battery in just one week. It's best to print the bottom part of the sphere with a resolution of 0.1mm, while the top can be printed with a slightly higher resolution ranging from 0.1mm to 0.15mm. Printing at a resolution of 0.2mm causes issues for me when attempting to assemble the two parts together.
