## Description

This SHT20 I2C temperature & humidity sensor is equipped with a waterproof probe. It comes with the 4C CMOSens® SHT20 temperature & humidity sensor chip and the probe has gone through a dual waterproof protection test. Note the waterproof part is the probe section that can be mounted into an environment. Take care with your setup to ensure adequate sealing is achieved for the back-section of the sensor if it will be exposed to high humidity.

The SHT20 I2C temperature & humidity sensor uses **Sensirion** techniques. The humidity sensor is of capacitive type and the temperature sensor is a bandgap. The SHT20 contains an amplifier, A/D converter, OTP memory and a digital processing unit. Compared with the early SHT1x series and SHT7x series, SHT20 shows strong reliability and long-term stability. It can measure the surrounding environment temperature and relative air humidity precisely.

The inner PCB has perfusion and encapsulation protection, and the probe enclosure is made of PE waterproof materials. This is a special waterproof breathable material that allows water molecules to seep in while blocking water droplets from seeping in at the meantime. The sensor won't be damaged even after a long time submerged in the water. There is also a built-in 10k Pull-up resistor and 0.1uf filter capacitor. It enables the sensor to be directly used with a microcontroller such as Arduino. We recommend[ DFRobot Gravity 4Pin Sensor Adapter](https://www.dfrobot.com/product-1626.html) convenient.
