> Ghost Hunting device made for my daughter.
Description
This ghost hunting device was created using an Adafruit HUZZAH32 – ESP32 Feather board. It employs various sensors and components to detect environmental anomalies, which are interpreted as potential ghostly activity.
Components
- Adafruit HUZZAH32 – ESP32 Feather: The microcontroller at the heart of the device.
- HC-SR04 Ultrasonic Sensor: Detects objects in front of the user. The closer an object gets, the more LEDs light up. If all five LEDs light up with no visible object, it suggests the presence of a ghost.
- BME280 Environmental Sensor: Monitors temperature, humidity, and pressure. This data is used to modulate other parts of the device.
- White LEDs: Five LEDs serve as an indicator for object detection based on the ultrasonic sensor.
- Buzzer: Beeps at varying speeds depending on how much the temperature deviates from the initial reading.
- Analog Gauge: Displays real-time humidity readings.
Usage
Humidity Display: The analog gauge provides real-time humidity readings to further indicate environmental shifts.
Power on the device: Once powered on, the device starts recording environmental data.
Object Detection: The ultrasonic sensor begins detecting objects. As distance decreases, more LEDs will light up. All five LEDs lighting up without a visible object indicates possible ghost activity.
Temperature Monitoring: The buzzer reacts to temperature changes. As the temperature increases, the beep rate accelerates. The device responds to temperature changes, not the absolute temperature level.
