Frequently Asked Questions

What is the operating voltage range for the SHT31A sensor?

The SHT31A-DIS-B10KS operates from a wide supply voltage range of 2.15V to 5.5V DC. This makes it directly compatible with both 3.3V and 5V microcontroller systems like Arduino, Raspberry Pi, and ESP32 without requiring a level shifter.

What communication protocol does this sensor use?

This sensor uses a standard I2C (Inter-Integrated Circuit) serial communication interface. It supports fast mode up to 1 MHz, allowing for high-speed data transfer and easy daisy-chaining with other I2C peripherals on the same bus.

What is the typical accuracy for humidity and temperature measurements?

The SHT31A provides typical accuracies of ±2% relative humidity and ±0.2°C for temperature. These are fully calibrated and linearized values, ensuring reliable and precise environmental data for critical monitoring applications.

Is the sensor output already calibrated?

Yes, the SHT31A is a fully factory-calibrated digital sensor. It provides linearized, temperature-compensated digital output via I2C, eliminating the need for user calibration or complex signal conditioning circuits in your design.
