Frequently Asked Questions

What is the operating voltage range for the GY-SHT41 sensor module?

The module operates from 1.1V to 3.6V DC. For use with 5V systems like Arduino Uno, a logic level converter is required to prevent damage to the sensor. Typical operation is at 3.3V.

What communication protocols does this sensor support?

The GY-SHT41 supports both I2C and SPI digital communication interfaces. The default is usually I2C, but the interface can often be selected via a solder Jumper or pin configuration on the module. Please check the specific module pinout.

How accurate are the temperature and humidity readings?

The sensor provides high accuracy with temperature measurements within ±0.2°C and relative humidity within ±1.8% RH. These values are typical for the integrated Sensirion SHT41 chip under specified conditions.

Is the sensor pre-calibrated, or does it require manual calibration?

The sensor is factory-calibrated with on-chip calibration data, providing accurate readings out of the box without requiring user calibration. This ensures consistent performance and simplifies integration.
