Sensirion SFM3300-AW Air Flow Sensor ±250 slm, Digital I2C Output
The Sensirion SFM3300-AW is a high-precision digital flow sensor delivering bidirectional measurement up to ±250 slm with a 0.5 ms update time via I2C interface. Its medical-grade PPSU/MABS enclosure and autoclavable design make it ideal for integration into neonatal ventilators, anesthesia machines, and diagnostic systems requiring fast, accurate respiratory flow data.
Features
- ±250 slm bidirectional air flow measurement with 14-bit digital resolution
- Ultra-fast 0.5 ms response time for real-time ventilation monitoring
- Medical-grade ISO5356-1 connectors and autoclavable (AW) PPSU/MABS housing
- Integrated digital temperature compensation and minimal dead space (<1 ml)
- I2C digital interface (up to 400 kHz) with default address 0x40

The SFM3300-AW employs Sensirion’s advanced CMOSens® technology, combining a thermal flow sensing element with integrated signal processing on a single chip. This MEMS-based design provides a calibrated digital output, ensuring high accuracy and long-term stability for critical medical gas flow applications. The sensor is compensated for temperature variations and outputs a linearized flow value directly via the I2C bus.
Engineered for demanding medical environments, the sensor features an autoclavable (AW) version with a PPSU/MABS enclosure, making it suitable for sterilization cycles. Its compact form factor and extremely low internal dead volume minimize interference with patient breathing circuits, while its robust construction resists ESD up to 8 kV contact discharge.
