SHT40-AD1P-R2 Frequently Asked Questions (FAQs)

  • Sensirion provides a recommended PCB layout guidelines in their application note AN502041, which includes layout recommendations for the SHT40-AD1P-R2.
  • The SHT40-AD1P-R2 comes calibrated from the factory, and no additional calibration is required. However, if you need to perform a recalibration, Sensirion provides a calibration procedure in their application note AN502041.
  • The maximum cable length for the I2C interface depends on the specific application and the capacitance of the cable. As a general guideline, Sensirion recommends keeping the cable length below 30 cm (12 inches) to ensure reliable communication.
  • The SHT40-AD1P-R2 is specified for temperatures up to 140°C (284°F). However, for high-temperature applications above 120°C (248°F), Sensirion advises to consult their application note AN502041 for specific guidance on temperature compensation and sensor performance.
  • The SHT40-AD1P-R2 has a sleep mode to reduce power consumption. To wake up the sensor, you need to send a specific command sequence to the sensor. Sensirion provides details on the sleep mode and wake-up procedure in the datasheet and application note AN502041.
