Description

The SHT30-DIS-F2.5KS from Sensirion is a next-generation digital humidity and temperature sensor based on proven CMOSens® technology. It combines a capacitive polymer sensing element for humidity with a band-gap temperature sensor, delivering fully calibrated and temperature-compensated digital signals via a fast I2C interface. The sensor’s robust design ensures high signal integrity and resistance to environmental contaminants.

Engineered for demanding applications, it features a wide supply voltage range, ultra-low power consumption, and optional ALERT and RESET functionality for advanced system control. Housed in a compact 8-pin DFN package, it is designed for high-volume integration into HVAC systems, weather stations, industrial process control, and portable instrumentation where precision and reliability are critical.

Key Features

  • High-Accuracy Digital Sensor: Provides calibrated humidity (±3% RH) and temperature (±0.3°C) readings with excellent long-term stability.
  • Fast I2C Communication: Supports clock frequencies up to 1 MHz with two selectable addresses (0x44, 0x45) for multi-sensor setups.
  • Wide Operating Ranges: Functions from 2.15V to 5.5V supply and across a -40°C to 125°C temperature span.
  • Ultra-Low Power Profile: Ideal for battery-operated devices with average current consumption below 1 mA and a 0.2 µA idle current.
  • Enhanced System Control: Features optional ALERT (high/low limits) and RESET pins for robust application design.
  • Robust & Compact Packaging: Housed in a miniature, surface-mount 8-pin DFN package (2.5 x 2.5 x 0.9 mm) for space-constrained PCBs.
  • Factory Calibrated & Linearized: Delivers ready-to-use digital values, eliminating the need for customer calibration.

Frequently Asked Questions

What is the operating voltage range for the SHT30 sensor?

The SHT30-DIS-F2.5KS operates from a wide supply voltage range of 2.15V to 5.5V DC. This makes it directly compatible with both 3.3V and 5V logic systems commonly found in Arduino, Raspberry Pi, ESP32, and other microcontroller platforms without requiring a level shifter.

How do I change the I2C address on the SHT30?

The SHT30 provides two selectable I2C addresses via the ADDR pin. Pulling the ADDR pin to VDD (logic high) sets the address to 0x45, while connecting it to GND (logic low or leaving it floating) sets the default address to 0x44. This allows up to two sensors on the same I2C bus.

What is the typical response time and measurement rate?

The sensor offers configurable measurement speeds. In high-repeatability mode, the conversion time is approximately 15 ms. In high-speed mode, it can perform a measurement in as little as 2.5 ms. The data can be polled at rates exceeding 1 Hz for dynamic environmental monitoring.

Is the SHT30 sensor suitable for outdoor or harsh environments?

Yes, with its operating temperature range of -40°C to 125°C and robust CMOSens® chip design, the SHT30 is well-suited for demanding environments. However, for prolonged outdoor use, proper PCB conformal coating or an IP-rated enclosure is recommended to protect against direct moisture and contaminants.

Does the sensor require calibration?

No, the SHT30 is factory calibrated and provides fully linearized digital output. Each sensor is individually calibrated and the calibration data is stored digitally on the chip, ensuring accurate readings out of the box and eliminating the need for user calibration.
