Gravity: SHT31‐F
Digital
Temperature and
Humidity Sensor
SKU:SEN0334
INTRODUCTION
Gravity: SHT31‐F digital temperature and humidity sensor is based upon the
Sensirion SHT31‐F sensor IC. Thanks to Sensirion’s CMOSens® technology, highly
integrated capacitive humidity sensing components and band‐gap temperature
sensing components, the SHT31‐F offers high reliability and long‐term stability
with low power consumption, fast response and strong anti‐interference ability.
The sensor supports I2C communication, and is compatible with 3.3V/5V
controllers like Arduino, micro:bit, ESP32. It is easy to achieve precise and high‐
reliability temperature and humidity sensing for urban environment monitoring,
intelligent buildings, industrial automation, smart home and other Internet of
Things applications.
SHT31‐F is the standard version of the SHT3x series. It provides humidity accuracy
±2% RH @ 0%RH~100%RH (at 25°C), and temperature accuracy±0.2°C @ 0℃‐90℃
(typical).
The SHT31‐F chip features a PTFE membrane dedicated to protecting the sensor
opening from liquids and dust according to IP67. It thus allows the sensor to work
under harsh environmental conditions, where spray water and high exposure to
dust might be challenging for accurate sensor performance. Due to minimal
package volume and the membrane’s high water vapor permeability, the
response time of the relative humidity and temperature signal is identical to the
value achieved by the uncovered sensor. Although the membrane option provides
perfect protection against water and dust ingress, it does not in general prevent
contamination from volatile chemicals.
