Airflow sensors Key benefits Detects air movement: Provides a simple way to monitor airflow or indicate changes in air direction or speed. Extremely lightweight: At 0.11 lb, the sensor is easy to install, handle, and transport. Paper construction: Lightweight, low-cost and recyclable material suited for short-term, disposable, or prototype applications. What it does and why you might need it Basic airflow detection for situations where a low-cost, lightweight sensing element is sufficient. Useful when you need a non-metallic, low-mass sensor that won’t significantly alter the airflow it measures. Simple form factor makes it easy to use in temporary setups, demonstrations, or proof-of-concept designs. Important attributes Function: Airflow sensing / airflow indication. Material: Paper — provides a thin, flexible sensing surface and easy disposal or recycling. Item weight: 0.11 lb — compact and portable. Suitability: Designed for basic monitoring and integration in low-complexity applications rather than precision industrial metrology. Typical use scenarios HVAC quick checks: Use as a low-cost indicator to verify airflow presence or direction during filter changes or duct inspections. Education and demonstrations: Ideal for classroom experiments or demonstrations that show airflow patterns or the effect of fans and vents. Prototyping and crafts: Integrate into early-stage prototypes, hobby projects, or models where a lightweight, disposable airflow element is preferred. Specifications Product type: Airflow sensor(s) Material: Paper Item weight: 0.11 lb Note: This product provides basic airflow sensing. For high-precision measurements or demanding industrial environments, consider a dedicated electronic airflow transducer or calibrated instrument.
