DFRobot SHT31 Weather-proof Temperature & Humidity Sensor
DFRobot SHT31 Weather-proof Temperature and Humidity Sensor is housed in a weather-proof enclosure and designed to be used safely in outdoor projects. The sensor is waterproof, but it is not suggested to be submerged in water. For in-water measurement, the DS18B20 Sensor is highly recommended. The sensor uses 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, ESP32.
Note: Although the sensor's temperature measurement range is -40°C to 125°C, it is recommended not to place the sensor at a temperature higher than 80°C since its shell is made of PE material.
