Barometer for altitude in Drone Programming - Mini Project: Build & Apply

Barometer for Altitude

📖 Scenario: You are programming a drone that uses a barometer sensor to measure altitude. The barometer gives pressure readings, and you want to convert these readings into altitude values to help the drone fly safely.

🎯 Goal: Build a simple program that stores pressure readings, sets a baseline pressure, calculates altitude from each reading using a formula, and then prints the altitude values.

📋 What You'll Learn

Create a list called pressure_readings with exact pressure values

Create a variable called baseline_pressure with a specific value

Use a list comprehension to calculate altitude values from pressure readings

Print the list of altitude values

💡 Why This Matters

🌍 Real World

Drones use barometer sensors to measure altitude for safe flying and navigation.

💼 Career

Understanding sensor data processing and simple formulas is important for drone programming and robotics jobs.

1

Create pressure readings list

Create a list called pressure_readings with these exact values: 1013.25, 1000.00, 990.00, 980.00, 970.00

Drone Programming

# Create the list pressure_readings with the given values
# Your code here

Need a hint?

Use square brackets [] to create a list and separate values with commas.

2

Set baseline pressure

Create a variable called baseline_pressure and set it to 1013.25 (standard sea level pressure in hPa).

Drone Programming

pressure_readings = [1013.25, 1000.00, 990.00, 980.00, 970.00]
# Create baseline_pressure variable with value 1013.25
# Your code here

Need a hint?

Just assign the number 1013.25 to the variable baseline_pressure.

3

Calculate altitude from pressure

Use a list comprehension to create a list called altitudes. Calculate altitude for each pressure reading using the formula: altitude = 44330 * (1 - (pressure / baseline_pressure) ** 0.1903). Use pressure as the variable inside the comprehension.

Drone Programming

pressure_readings = [1013.25, 1000.00, 990.00, 980.00, 970.00]
baseline_pressure = 1013.25
# Create altitudes list using list comprehension and the given formula
# Your code here

Need a hint?

Use the formula exactly and write a list comprehension with for pressure in pressure_readings.

4

Print altitude values

Write a print statement to display the altitudes list.

Drone Programming

pressure_readings = [1013.25, 1000.00, 990.00, 980.00, 970.00]
baseline_pressure = 1013.25
altitudes = [44330 * (1 - (pressure / baseline_pressure) ** 0.1903) for pressure in pressure_readings]
# Print the altitudes list
# Your code here

Need a hint?

Just print the variable altitudes to see the list of altitude values.
