Raspberry Pi ghost hunting involves using the versatile mini-computer to build custom paranormal investigation tools, like Spirit Boxes that generate random words from sensor data, PKE Meter-style WiFi scanners, motion-activated scare props with cameras, or devices that log environmental changes (temp, EMF, audio) for evidence of activity, often using Python and various add-on sensors to create DIY ghost detection equipment.

Common Raspberry Pi Ghost Hunting Projects:

DIY Spirit Box/Ghost Box:
Function: Scans radio frequencies or picks words from a list, using sensor data (temp, humidity) to add randomness.
Build: Uses a Pi with a microphone, speaker, display, and sensors, often programmed in Python.

PKE Meter Replica:
Function: Detects WiFi signals and displays them, with moving arms (servos) reacting to signal strength, inspired by Ghostbusters.
Build: Raspberry Pi Pico W, 3D printed case, servos, screen.

Environmental Sensor Logger:
Function: Records fluctuations in temperature, EMF (voltage), humidity, or motion (PIR sensor).
Build: Raspberry Pi with appropriate sensors (like a Sense HAT or others) and Python scripts.

Motion-Activated Camera/Scare Device:
Function: Triggers recording or a scare effect (e.g., a scream) when motion is detected.
Build: Raspberry Pi with a camera module and PIR sensor, often using Python.

How to Get Started:
Choose Your Pi: A standard Raspberry Pi (like a 3B+ or 4) or a smaller Pico W for portable projects.
Add Sensors: Integrate temperature, humidity, PIR (motion), EMF, or audio sensors.
Code (Python): Write scripts to read sensor data, generate sounds/words, control LEDs, or manage cameras.
Assemble: Use 3D printed cases or existing enclosures (like old flashlights) to house your device.
These projects leverage the Pi's flexibility to create unique, customizable tools for exploring paranormal phenomena.
