Pressure Sensors

SDP31Differential pressure sensor±500 PaI2CSensirionAirflow sensing

SDP31 is a calibrated I2C differential pressure sensor for air-flow and pressure measurements up to ±500 Pa.

Best for

  • Fast differential-pressure monitoring
  • Airflow sensing using pressure drop
  • Portable and battery-powered instruments

Avoid if

  • The application requires a range greater than ±500 Pa
  • The measured medium is condensing or incompatible with the specified media

Check before use

  • Use a 100 nF supply decoupling capacitor close to VDD
  • Do not connect ADDR directly to VDD
  • Keep the IRQn pin floating when it is unused
  • Protect pneumatic ports from flux, dust, and liquids during assembly
