INTRODUCTION
This is an SHT31
Temperature & Humidity sensor housed in a weather-proof enclosure. The
sensor is designed to be waterproof so you can use it safely in outdoor
projects. Please note that although the sensor is waterproof, it is not
suggested to submerge it in water. For in-water measurement, the
DS18B20 Sensor is highly recommended.
Thanks to Sensirion’s
CMOSens® technology, highly integrated capacitive humidity sensing components,
and band-gap temperature sensing components, the SHT31 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, and ESP32.
SHT31 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°C ~90°C (typical).
Note: Although the temperature measurement
range of the sensor is - 40 ~ 125 ℃, we recommend not to place the sensor at a temperature higher
than 80 ℃ since its shell is made
of PE material.
