Review of SHT30 Sensor for Arduino and other microcontrollers

Repost of Review from: Artsofcircuits.com Description SHT30 is high accuracy, Fully calibrated, linearized, and temperature compensated digital output (I2C interface) Digital Temperature and Humidity Sensor Shield For WeMOS-D1 ESP8266 WiFi boards. SHT3x-DIS Sensor is the next generation of Sensirion’s temperature and humidity sensors. It builds on a new CMOSens® sensor chip that is at the heart of Sensirion’s new humidityand temperatureplatform.The SHT3x-DIS has increased intelligence, reliability and improved accuracy specifications compared to its predecessor. Its functionality includes enhanced signal processing, two distinctive and user selectable I2C addresses and communication speeds of up to 1 MHz. Additionally, the wide supply voltage range of 2.4 V to 5.5 V guarantees compatibility with diverse assembly situations. All in all, the SHT3x-DIS incorporates 15 years of knowledge of Sensirion, the leader in the humidity sensor industry Features Wide supply voltage range, from 2.4 V to 5.5 V I2C Interface with communication speeds up to 1 MHz and two user selectable addresse Typical accuracy of 1.5 % RH and 0.2 °C for SHT3x Very fast start-up and measurement time Technical Specifications Humidity Sensor Specifications Parameter Condition Value Units SHT30 Accuracy tolerance1 Typ. 3 %RH Max.
