Bluetooth App Air Purifier Case Study
Smart Air Purifier Control System
Turning sensor inputs into coordinated fan control, display feedback, local interaction and Bluetooth App operation.
The Challenge
Keep sensor data, fan behavior and App commands synchronized
Sensor readings, fan stages, air-quality indicators, the displayed value and Bluetooth App status must move together. Local and App commands cannot create conflicting product states.
The connected board also needs reliable programming and functional-test access during production.
The Approach
Use one state model for local and Bluetooth App control
- Map sensor inputs to fan stages, display status, indicators and App-visible modes.
- Define Bluetooth commands and feedback around the same local-control logic.
- Review fan outputs, power, antennas, connectors and test access.
- Verify local and App operation together before freezing files for NPI.
Control Architecture
A connected air-quality control platform
Air-Quality Inputs
Acquire particulate or related sensor signals and apply stable response logic.
Fan Drive
Control fan stages or speed according to product mode and sensed conditions.
Bluetooth App
Exchange commands and product status through the connected user interface.
Display & Local Input
Keep local values, modes and commands aligned with App operation.
Power & Interfaces
Coordinate power, sensors, fan outputs, connectors and communication circuits.
Production Access
Provide programming, connectivity and functional-test points.
Validation & Release
Validate sensors, fan response and Bluetooth App control together
Functional testing covers power-up, sensor response, fan outputs, local input, displayed values, Bluetooth pairing, App commands and status feedback.
- Main-board power and fan-output checks
- Sensor and Bluetooth communication verification
- Local display, indicator and input testing
- App command and status-feedback checks
Production handoff
The approved hardware, firmware version, Bluetooth configuration, programming method and functional-test sequence are documented for NPI and production.
