Temperature Sensor Display Housing

thingiverse

This is a housing for one of those low-cost temp sensors you can find on banggood or other similar websites. Unfortunately, I've lost track of the model number I used and won't be able to provide it here. I made sure to include a well-ventilated area next to the display for installing a small circuit board. In this setup, I utilized a 78l05 linear regulator to step down the voltage from 12v (my lights) to 5v (sensor). This configuration works out perfectly because the sensor I have only draws approximately 25mA at most, so there's no heat issue whatsoever.
