This SHT20 I2C temperature & humidity sensor is equipped with waterproof probe. It comes with the 4C CMOSens® SHT20 temperature & humidity sensor chip and the probe has gone through a dual waterproof protection test. The SHT20 I2C temperature & humidity sensor adopts Sensirion techniques. Apart from the humidity sensor of capacitive type and the temperature sensor, the SHT20 contains an amplifier, A/D converter, OTP memory and a digital processing unit. Compared with early SHT1x series and SHT7x series, the SHT20 shows a strong reliability and long-term stability. It can measure the surrounding environment temperature and relative air humidity precisely. There is also a built-in 10k Pull-up resistor and 0.1uf filter capacitor. It enables the sensor to be directly used with the microcontroller such as Arduino. We recommend DFRobot Gravity 4Pin Sensor Adapter convenient.
