SHT40-AD1B-R2 Frequently Asked Questions (FAQs)

  • Sensirion recommends a reflow soldering profile with a peak temperature of 260°C, a dwell time above 220°C of 30-60 seconds, and a cooling rate of 4°C/s or less.
  • Handle the device by the package body only, avoid touching the sensor membrane or electrical contacts, and use an anti-static wrist strap or mat to prevent electrostatic discharge.
  • Store the device in a dry, cool place (20°C to 30°C, 20% to 60% RH) in its original packaging or a similar environment to prevent moisture absorption.
  • Yes, but ensure the device is properly sealed and protected from direct exposure to water, and consider using a conformal coating or potting compound to prevent moisture ingress.
  • The SHT40-AD1B-R2 is calibrated by Sensirion during manufacturing, but you can perform a one-point calibration using a reference humidity source and the device's built-in heater for temperature calibration.
