Frequently Asked Questions

What is the communication protocol for this SHT30 module?

This module uses a simple TTL-level serial interface (UART) configured at 9600 baud by default. It transmits calibrated temperature and humidity data as ASCII strings, making it easy to read with any microcontroller's serial port without requiring specialized I2C or SPI libraries.

Can I power this sensor directly from a 5V Arduino pin?

Yes, the module is designed to operate from a 3.3V to 5V DC supply. You can connect its VCC pin to the 5V output from an Arduino board. Ensure your microcontroller's serial RX pin is 5V tolerant if connecting directly, or use a logic level converter if your MCU operates at 3.3V logic.

What is the difference between auto-reporting and manual modes?

In auto-reporting mode, the module continuously sends sensor data at a fixed interval without host intervention. In manual mode, the host microcontroller must send a specific command to request a single reading, providing greater control over power consumption and bus traffic for optimized system design.
