Sensor Watch: Catch the Reading That Doesn't Belong

Feed in a stream of sensor readings, compute the normal range on the fly, and flag the exact moment a reading drifts too far from it, the anomaly detector behind every monitored device.

PythonBeginnerFor fun, and portfolio-worthy

What you'll be able to build

Feed in a stream of sensor readings, compute the normal range on the fly, and flag the exact moment a reading drifts too far from it, the anomaly detector behind every monitored device. Along the way you pick up real, transferable Python skills, not just this one project:

  • lists of numeric readings
  • running mean with the statistics module
  • threshold-based deviation checks
  • for loops flagging out-of-range values
  • dicts to tag each anomaly with its index
  • a formatted anomaly report

A course like this one

Yours is built from your own placement, so module count and depth will differ. This map shows what a beginner-level Python learner building Sensor Watch actually gets.

  1. Module 1: Values and output6 lessons

    Builds the script for your Sensor Watch.

  2. Module 2: Collections and data6 lessons

    Builds the data flow workflow for your Sensor Watch.

  3. Module 3: Branching and state6 lessons

    Builds the function that powers your Sensor Watch.

  4. Module 4: Functions and tests6 lessons

    Builds the reusable module for your Sensor Watch.

  5. Module 5: Files, APIs, and persistence6 lessons

    Builds the service boundary for your Sensor Watch.

  6. Module 6: Packaging and review3 lessons

    Builds the release package for your Sensor Watch.

How the lessons actually work

Leans on:statistics

Every lesson has you predict what a piece of Python code will output before you run it, then run it for real in your browser and fix what you got wrong. Each module ends in a challenge gate with hidden tests, so you can't advance until your code actually works. The course closes with a capstone that assembles everything into Sensor Watch, and a runnable proof page tied to your own code.

Common questions

How long does the Sensor Watch: Catch the Reading That Doesn't Belong course take?

about 8.5 hours, across 6 modules and 33 lessons, at roughly 15 minutes per lesson. Your own course may run shorter or longer, since it's sized to your placement result, not a fixed template.

Do I need experience?

No. This is a beginner-tier Python project, built for someone writing their first real Python programs.

How much does it cost?

$15 one-time, no subscription. The first module is free, so you can see exactly how the course teaches before you pay for the rest.

No subscription. Module one is free.
