Description

The SHT85 digital humidity and temperature sensor represents Sensirion’s best-in-class platform, building upon the proven SHT3x sensor core for enhanced long-term stability. Its unique SIP-4 package design optimizes thermal coupling to the environment while decoupling from potential heat sources on the host PCB, ensuring measurement integrity.

The sensor utilizes a capacitive sensing element for humidity and a band-gap sensor for temperature, both factory-calibrated and delivering a digital signal via the I2C interface. The integrated PTFE membrane provides IP67-level protection against dust and temporary immersion in water, safeguarding the sensor without compromising the fast 8-second (t63%) response time for humidity measurements.

Key Features

  • Superior Measurement Accuracy: Typical accuracy of ±1.5% RH and ±0.1°C with excellent long-term stability.
  • Extended Voltage & Temperature Range: Operates from 2.15V to 5.5V DC across a -40°C to 105°C measurement span.
  • IP67 Protected Sensor Face: PTFE membrane shields the sensing element from dust and liquids, ensuring durability in demanding environments.
  • Fast Digital Response: Provides a humidity response time (t63%) of 8 seconds for dynamic environmental monitoring.
  • Factory Calibrated & Certified: Includes a calibration certificate for traceable accuracy right out of the package.
  • Optimized Thermal Performance: Package design minimizes self-heating effects and promotes accurate ambient readings.
  • I2C Communication Protocol: Simple two-wire digital interface for easy connection to most microcontrollers and SBCs.
  • Low Power Consumption: Maximum supply current of 1000µA enables use in portable and wireless sensing nodes.

Applications

  • HVAC and Building Automation Systems for precise climate control and energy management.
  • Industrial Process Monitoring and Environmental Chambers requiring stable, accurate humidity and temperature data.
  • Weather Stations and Agricultural Monitoring Networks for outdoor environmental sensing.
  • Medical Devices and Incubators where reliable environmental parameters are critical.
  • Data Center and Server Room Monitoring to prevent equipment damage from condensation or overheating.

Frequently Asked Questions

What is the operating voltage range for the SHT85 sensor?

The SHT85 operates from a wide supply voltage range of 2.15V to 5.5V DC. This makes it compatible with both 3.3V and 5V logic systems, including Arduino, Raspberry Pi, and various battery-powered IoT platforms without requiring a level shifter.

How do I connect and communicate with the SHT85 sensor?

The SHT85 uses a standard I2C (2-wire) digital interface. Connect the VDD (2.15-5.5V), GND, SDA (data), and SCL (clock) pins to your microcontroller. The sensor has a default I2C address and supports standard Sensirion commands for reading humidity and temperature data.

What does the IP67 rating on the SHT85 mean for its use?

The IP67 rating indicates the sensor's face is protected against dust ingress and can withstand temporary immersion in water up to 1 meter for 30 minutes. This allows for reliable operation in humid, dusty, or outdoor environments where condensation or occasional splashing may occur.

What is the typical accuracy and response time of the SHT85?

The SHT85 offers a typical accuracy of ±1.5% for relative humidity and ±0.1°C for temperature. The humidity sensor has a fast response time (t63%) of approximately 8 seconds, enabling it to track rapid environmental changes effectively for dynamic control systems.

Does the sensor come pre-calibrated?

Yes, the SHT85 is factory calibrated, and each unit includes a calibration certificate. This ensures high out-of-the-box accuracy and traceability, eliminating the need for user calibration in most applications and providing reliable data from the first power-up.
