Thought this group would find this sensor housing simple build amusing.
Basic premise is repurposing a little desk toy TARDIS for something more than a little cell battery powered light at the top. Incorporating an esp32c3 with ld2450 sensor to become a cute stealth presence setup. All pre/post testing shows good accuracy and sending through the minimal plastic wall.

Future possibilities:
Get the light back online and tied into HA for triggering
Find a teeny speaker for timey wimey sound effects
