Frequently Asked Questions

Q: What microcontrollers is the SHT31 sensor module compatible with?

A: The SHT31-DIS sensor module uses the standard I2C communication protocol, making it compatible with a wide range of microcontrollers including Arduino (Uno, Nano, Mega), Raspberry Pi, ESP8266, ESP32, STM32, and any other platform that supports I2C (SDA/SCL). Integration is straightforward using widely available open-source libraries.

Q: Can I use multiple SHT31 modules on the same I2C bus?

A: Yes! The SHT31-DIS supports two selectable I2C addresses (0x44 and 0x45) via the ADDR pin, which means you can connect two modules on the same bus simultaneously. For larger networks with more sensors, an I2C multiplexer (such as the TCA9548A) can be used to expand further.

Q: What is the difference between buying 1 vs. 5 pieces?

A: The listing allows you to select a quantity of 1 to 5 individual SHT31 sensor modules. Buying in multi-packs is ideal for multi-node sensing setups, redundancy in critical projects, or simply keeping spares on hand. Each module in the pack is identical in specifications and quality.

Q: Does the SHT31 module come with header pins pre-soldered?

A: Header pin configuration may vary depending on the selected option. Please check the product images and your order details for the exact configuration. The compact board is designed to be breadboard-friendly and easy to integrate into custom PCB layouts.
