Mass Air Flow Sensor, Open-drain, 10 Pin

The FS3000-1005 is a fully integrated, MEMS-based air velocity (flow) sensor designed for precise and reliable measurement of gas flow in compact systems. It utilizes a thermal transfer principle and includes onboard signal conditioning, calibration, and digital output, making it suitable for direct interface with microcontrollers.

This sensor is optimized for low-flow air or gas applications such as HVAC systems, environmental monitoring, airflow detection in consumer electronics, and industrial process control. Its compact surface-mount package allows easy integration into space-constrained designs.
