Description

The Sensirion SHT25 is a high-performance digital sensor that combines a capacitive polymer humidity sensing element with a band-gap temperature sensor. It features integrated signal conditioning, an analog-to-digital converter, and an I2C serial interface on a single CMOSens® chip, delivering fully calibrated, linearized digital outputs for both humidity and temperature.

Engineered for long-term stability and minimal drift, the SHT25 is housed in a compact DFN-6 package, making it suitable for automated PCB assembly processes. Its low power consumption and wide supply voltage range of 2.1V to 3.6V make it ideal for integration into space-constrained and power-sensitive applications requiring precise environmental monitoring.

Key Features

High-Precision Sensing: Provides industry-leading humidity accuracy (±1.8% RH) and integrated temperature measurement.
Fully Digital I2C Output: Delivers calibrated, linearized digital signals, eliminating the need for external signal conditioning.

Frequently Asked Questions

What is the operating voltage range for the SHT25 sensor?

The SHT25 operates from a supply voltage of 2.1V to 3.6V DC. It is designed for direct compatibility with 3.3V logic systems commonly found in microcontrollers like ESP32, STM32, and Raspberry Pi. Ensure your power supply is within this range for proper functionality and to avoid damage to the sensor.

How do I communicate with the SHT25 sensor?

The SHT25 uses a standard I2C (Inter-Integrated Circuit) serial communication interface. It has a 7-bit I2C address, and communication follows the standard I2C protocol for reading humidity and temperature data. You will need to connect the SDA (data) and SCL (clock) lines to your microcontroller, along with power and ground.

Is the SHT25 sensor calibrated, and does it require manual calibration?

Yes, the SHT25 is fully factory-calibrated. Sensirion's CMOSens® technology provides individual calibration coefficients stored in the chip's non-volatile memory. This means no user calibration is required—the sensor outputs accurate, linearized digital values directly upon power-up, simplifying system integration.

What is the physical package of the SHT25, and how is it mounted?

The SHT25 comes in a surface-mount DFN-6 (Dual Flat No-Lead) package. It is designed for reflow soldering onto a printed circuit board (PCB). This compact package is robust and suitable for automated assembly processes, making it ideal for high-volume production of embedded systems and sensor modules.
