Build with SHT30 — Datasheet Specs & AI Design Help

00 — Overview

What the SHT30 does

The SHT3x-DIS family comprises fully calibrated digital humidity and temperature sensors available in SHT30, SHT31, and SHT35 variants. These devices operate on a wide supply voltage range of 2.15 V to 5.5 V and feature an I2C interface supporting speeds up to 1 MHz. The SHT35 model achieves typical accuracy of ±1.5 %RH and ±0.1 °C, while the SHT30 and SHT31 offer ±2 %RH humidity accuracy. With a specified range of 0 to 100 %RH and -40 to 125 °C, these sensors integrate into diverse applications requiring precise environmental monitoring. Their tiny 8-Pin DFN package ensures compact integration without sacrificing performance or reliability.
