SHT45-AD1F-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 (20-30°C, 40-60% RH) in its original packaging or a similar environment to prevent moisture absorption.
  • Yes, but ensure proper sealing and protection of the device from direct exposure to water, condensation, or high humidity to prevent damage or degradation.
  • The SHT45-AD1F-R2 is calibrated during manufacturing, but you can perform a one-point calibration using a reference temperature and humidity source to improve accuracy.
