Using the MagicMirror<\/strong> open source, modular smart mirror platform for the HUD. Modules include: Synced Google Calender, Local Weather, Daily Quotes, and more.<\/p>

\u00a0<\/p>

Motion Detection using RCWL-0516<\/strong> Doppler Radar Microwave Sensor. Offers omni-directional detection, longer range, and can detect through glass (vs. PIR: limited detection angle, cannot detect through glass, and the biggest offender, looks like a wart). Minor caveat with RCWL-0516, it detects too well. False positives from movement in adjacent rooms can occur. To adjust the range, I replaced a specific SMD resistor with a Trim Pot (learn more in links below).<\/p>

\u00a0<\/p>

Custom written Python scripts: Primary script provides communication between Motion Sensor, LEDs, Monitor, and Pi<\/strong> (see video demo). Another script to automate Cooling Fan<\/strong>, integrated Transistor and Flyback Diode to control on\/off state. Scripts run continuously on boot using cron jobs.<\/p>
