Up You Go! (Smart Mountaineering Altimeter & Rock Inclinometer)

Source:

Equip a mini mountaineer figure with a 3-axis MPU6050 accelerometer/gyroscope inclinometer and BMP280 barometric altimeter. As the figure climbs up a rock wall, the system displays slope angle (°), altitude (m), and dropping oxygen levels.

Categorisation

Props & Materials Required

  • •Mini rock climbing wall model with movable climber figure
  • •MPU6050 3-axis accelerometer / gyro sensor (measures slope incline)
  • •BMP280 barometric pressure & altitude sensor
  • •ESP32 controller board
  • •0.96-inch OLED display screen
  • •DFPlayer Mini MP3 module + 3W speaker

Step-by-Step Instructions

1

Measure Rock Slope Incline

Tilt climbing wall to steep angle. MPU6050 gyro reads 'Slope Angle: 75° (STEEP CLIFF!)'.

2

Climb up Mountain Wall

Move climber figure up the wall. BMP280 sensor reads rising altitude: '500m... 2,000m... 4,500m!'.

3

Monitor Air Pressure & Oxygen Drop

As altitude reaches 4,500m, barometric pressure drops. OLED displays 'Oxygen Level: 60% (THIN AIR!)'.

4

Mountaineering Survival Audio

Speaker plays cold wind sounds: 'High Altitude Reached! Use Carabiner clips, ropes, and take deep breaths! Expedition successful!'

Why It Works & Notes

Up You Go! shares Sangeeta Arora's mountaineering camp experience (climbing steep slopes, carrying heavy rucksacks, altitude sickness). Measuring real slope angles with 3-axis gyroscopes and altitude with barometer sensors makes expedition science real.
