Smart Radon Fan — adaptive control for residential radon mitigation

A controller monitors indoor radon and automatically turns a mitigation fan on and off using threshold + hysteresis logic. The result: better efficiency, lower utility cost, less noise, and longer fan life — all without relying on cloud services.

Designed for stand-alone operation on a local network (no subscription required).

Why homeowners want automation

Most residential radon fans run continuously. This system adds modern feedback control: measure radon, switch the fan intelligently, log results, and visualize performance — automatically.

Utility cost savings

Reduces unnecessary fan runtime while maintaining safe indoor radon levels.

Noise reduction

Less fan operation can reduce acoustic noise around the home.

Improved fan life

Hysteresis-based control avoids rapid cycling and can reduce wear.

Expected modern automation

Closed-loop control for a common residential utility — simple, practical, overdue.

Local-first, autonomous operation

The controller communicates locally with a radon sensor and a controllable power interface (e.g., a smart plug), applies threshold + hysteresis logic, logs measurements and fan state, and generates historical visualizations accessible on your LAN.

How it works

A radon sensor reports indoor concentrations. A controller compares the readings to configurable on/off thresholds, applies hysteresis, and turns the mitigation fan on or off through a controllable power interface.

System components

  • Radon sensor providing short-term and/or long-term readings.
  • Controller (embedded platform) running the automation logic.
  • Controllable power interface (smart plug / relay) powering the fan.
  • Radon mitigation fan and vent stack as commonly installed in homes.

Installer-friendly setup

  • Simple onboarding flow accessible from a smartphone.
  • Runs locally on your network and is viewable via IP address.
  • Logs radon and fan state history for confidence and verification.

See what the system records

The controller logs radon readings and fan state, and generates time-series visualizations accessible on a local network. This provides transparency and helps validate mitigation performance.
