Frequently Asked Questions

What is the operating voltage range for the SHT31-DIS sensor?

The SHT31-DIS sensor operates from 2.4V to 5.5V DC, making it directly compatible with both 3.3V and 5V microcontroller systems like Arduino, ESP32, and Raspberry Pi without requiring level shifting.

How do I communicate with this sensor using the I2C interface?

The sensor uses a standard I2C protocol. You need to connect the SDA (data) and SCL (clock) lines to your microcontroller, along with power and ground. The default I2C address is 0x44, but an alternate address (0x45) can be selected. Refer to the Sensirion datasheet for the precise command set for initiating measurements and reading data.

Is the sensor calibrated, and what is its accuracy?

Yes, the SHT31-DIS is fully factory-calibrated, providing linearized digital outputs. The typical humidity accuracy is ±2% RH across a wide range. The integrated temperature sensor provides high precision for compensation and standalone measurement within its specified range.

What is the package type, and how is it mounted?

The sensor comes in a compact DFN-8 (Dual Flat No-lead) surface-mount package measuring 2.5 x 2.5 mm. It is designed for reflow soldering onto a PCB, requiring appropriate pad layout and soldering profile as specified in the datasheet for reliable assembly.
