Frequently Asked Questions

What is the operating voltage range for the GY-SHT30-D module?

The module 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 a logic level shifter.

How do I change the I2C address of this sensor?

The SHT30 sensor on this module supports two fixed I2C addresses: 0x44 and 0x45. The address is typically selected by the module's PCB design (e.g., a solder Jumper). Consult the specific module's documentation or inspect the board for address selection pads.

What is the typical response time for a measurement?

The sensor has a response time greater than 2 seconds. For the highest accuracy readings, it is recommended to allow sufficient stabilization time after power-up and to adhere to the timing specifications in the SHT30 datasheet for measurement commands.

Is the sensor calibrated, and do I need to calibrate it myself?

Each SHT30 sensor is factory calibrated by Sensirion, and the unique calibration coefficients are stored in the chip's One-Time Programmable (OTP) memory. This ensures high accuracy out-of-the-box, eliminating the need for user calibration in most applications.
