This is an SHT31 Temperature & Humidity sensor housed in a weather-proof enclosure. The SHT31 sensor is designed to be waterproof so you can use it safely in outdoor projects. Please note that although the SHT31 temperature and humidity sensor is waterproof, it is not suggested to submerge it in water. For in-water measurement, the DS18B20 Sensor is highly recommended.

Thanks to Sensirions 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 I2C temperature sensor supports I2C communication and is compatible with 3.3V/5V controllers like Arduino, micro: bit, and ESP32. This high accuracy digital sensor is ideal for environmental monitoring.

SHT31 is the standard version of the SHT3x series digital sensor. It provides humidity accuracy 2%RH@0% RH~100% RH (at 25C), and temperature accuracy0.2C@ 0C ~90C (typical).

Although the temperature measurement range of the SHT31 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. This outdoor temperature and humidity sensor ensures stable performance in varied conditions.
