SNZB-03 TV Proximity Sensor

Introduction

• Wanted to stop people touching the TV
• TV is mounted with a wall at other side of TV cabinet
• A correctly masked motion sensor at one side could be a good deterrent

Vitamins

• Sonoff SNZB-03 PIR Motion Sensor
  • etc. software for motion sensor to connect
• Adhesive - I used 3M Command strips

Design

• Modelled in Fusion 360 (file included for remixing)
• Not particularly parametric as I did not expect to need to make another anytime soon
• Snug slide fit for Sonoss SNZB-03 PIR Motion Sensor
  • Can be removed with a knife levering on the sensor dome but otherwise stays put
• No supports required

Printing

• Print STL as downloaded, it should not need any supports
• My settings were
  • 0.2mm
  • 20% support cubic infill
  • 3 verticall walls, 5 bottom/top walls
  • 30s minimum layer time

Automation

• Tested on Home Assistant 2023.12.3
