Frequently Asked Questions

What is the supply voltage range for the SHTC3 sensor?

The SHTC3 operates from 1.62V to 3.6V DC. This wide range makes it directly compatible with common 1.8V and 3.3V logic systems. For use with 5V microcontrollers, a level shifter or appropriate voltage divider on the I2C lines is required to prevent damage.

How do I communicate with the SHTC3 using I2C?

The SHTC3 uses a standard I2C interface supporting Fast Mode Plus up to 1 MHz. It has a 7-bit I2C address. You can send measurement commands and read back humidity and temperature data packets. The datasheet provides the specific command set and timing diagrams for initiating measurements and reading results.

What is the typical power consumption of the SHTC3?

In its low-power measurement mode, the SHTC3 has an average current consumption as low as 0.5 µA when sampling at 1 Hz. The operating current during active measurement is between 0.43 mA and 0.9 mA. This ultra-low power profile is specifically designed for battery-powered and energy-harvesting applications.

Is the SHTC3 sensor calibrated, and is it suitable for high-temperature environments?

Yes, each SHTC3 is individually factory-calibrated and provides NIST-traceable accuracy. It is designed for a wide operating temperature range from -40°C to +125°C, making it suitable for harsh environment monitoring in industrial, automotive, or outdoor applications where temperature extremes are common.
