Frequently Asked Questions

What is the operating voltage range for the HTU31D sensor?

The HTU31D sensor operates from a supply voltage range of 3.0V to 5.5V DC. This wide range makes it compatible with both 3.3V and 5V logic microcontroller platforms like Arduino, Raspberry Pi, and ESP32 without requiring a level shifter.

Does this sensor require calibration before use?

No, the HTU31D is fully interchangeable and does not require user calibration. Each sensor is factory-calibrated and features serial individual marking. This ensures consistent, accurate readings right out of the package and simplifies inventory management for production.

Is the HTU31D sensor suitable for surface-mount assembly?

Yes, the sensor comes in a compact DFN-6 package and is fully compatible with standard reflow soldering processes. Its robust design withstands the high temperatures of SMT assembly, making it ideal for high-volume, automated manufacturing of PCBs.

What is the communication protocol and how do I connect it to my microcontroller?

The sensor communicates via the I2C (Inter-Integrated Circuit) protocol. You need to connect the SDA (data) and SCL (clock) lines to your microcontroller's corresponding I2C pins, along with VDD (3-5.5V) and GND. Pull-up resistors are typically required on the I2C bus lines.
