Overview

The SHT31-DIS-F2.5KS is a high-accuracy digital humidity and temperature sensor featuring a wide supply voltage range from 2.15V to 5.5V. It utilizes Sensirion proprietary CMOSens technology to provide fully calibrated and linearized I2C output with a typical humidity accuracy of +/-2% RH. The 8-pin DFN package includes an integrated heater for clearing condensation and ensuring long-term stability in high-humidity environments.

Why Choose This Part

The sensor offers exceptional reliability with NIST traceability and a fast 8-second response time. Its ultra-low power consumption of 0.2uA in standby and small 2.5mm x 2.5mm footprint make it ideal for battery-operated wireless IoT nodes.

Applications

HVAC Systems
Precise climate control in residential and industrial air conditioning units for energy efficiency and comfort.
Weather Stations
Reliable outdoor environmental monitoring across a broad -40 to 125 degrees Celsius operating range.
Medical Respiratory Devices
Monitoring humidity levels in CPAP and ventilator circuits to prevent patient airway dryness.
Data Center Environmental Monitoring
Rack-level sensing to prevent hardware failure due to condensation or static discharge risks.
