Sensirion

Sensirion provides sensors for air quality, humidity, temperature, differential pressure and liquid flow. Specify the complete ordering code when requesting components through SpareX.

Product selection

SCD41 is a photoacoustic NDIR CO₂ sensor with a specified measurement range of 400–5000 ppm and single-shot operation. SHT45 is an I²C humidity and temperature sensor for board-level integration. SPS30 uses laser scattering to measure particulate matter and provides I²C and UART interfaces. SDP31 measures differential pressure up to ±500 Pa. SLF3S-1300F measures bidirectional liquid flow up to ±40 ml/min, with manufacturer calibrations for water and isopropyl alcohol.

Integration and replacement

Confirm the package, supply voltage, interface, connectors and operating conditions. An evaluation kit and a bare sensor are different order items. For replacements, share the installed part marking and connection details; similar measuring functions do not establish electrical or mechanical compatibility.
