SHT40-BD1B-R2 Frequently Asked Questions (FAQs)

  • The recommended operating voltage range for the SHT40-BD1B-R2 is 2.15 V to 5.5 V.
  • The SHT40-BD1B-R2 has a built-in POR circuit that ensures a reset when the power supply is turned on. To handle POR, ensure a stable power supply voltage and add a 1 μF capacitor between VDD and GND. Additionally, use a voltage regulator to maintain a stable voltage supply.
  • The recommended clock frequency for I2C communication with the SHT40-BD1B-R2 is up to 400 kHz in standard mode and up to 1 MHz in fast mode.
  • The SHT40-BD1B-R2 comes calibrated from the factory, and no additional calibration is required. However, if you need to perform a calibration, Sensirion provides a calibration protocol and software tools to support this process.
  • The typical response time for the SHT40-BD1B-R2 temperature sensor is 1 second, and for the humidity sensor, it is 8 seconds.
