Frequently Asked Questions

What is the operating voltage range for the SHT30A-DIS-B sensor?

The SHT30A-DIS-B operates from a wide supply voltage range of 2.4 V to 5.5 V DC. This makes it directly compatible with both 3.3 V and 5 V microcontroller systems like Arduino, Raspberry Pi, and ESP32 without requiring a level shifter.

How do I communicate with this sensor and what are the I2C addresses?

Communication is via the standard I2C serial interface, supporting speeds up to 1 MHz. The sensor provides two user-selectable 7-bit I2C addresses: 0x44 (default) and 0x45, allowing you to connect two sensors on the same bus for multi-point sensing.

Is this sensor suitable for automotive or harsh environment applications?

Yes, the SHT30A-DIS-B is specifically qualified to the automotive AEC-Q100 standard. It is designed to deliver reliable, high-precision measurements across an extended operating temperature range of -40°C to 125°C, making it ideal for demanding automotive, industrial, and outdoor applications.

What is the power consumption profile of this sensor?

The sensor features ultra-low power consumption. In idle (sleep) mode, it draws only 0.2 µA. During an active measurement, the average current is between 600 µA and 1500 µA, depending on the selected measurement resolution and repeatability mode.
