## Description

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 dual waterproof protection test. The SHT20 I2C temperature & humidity sensor adopt Sensirion techniques. Except the humidity sensor of capacitive type and the temperature sensor of band gap , SHT20 contains an amplifier, A/D converter, OTP memory and a digital processing unit. Compared with early SHT1x series and SHT7x series, SHT20 shows a strong reliability and long-term stability. It can measure surrounding environment temperature and relative air humidity precisely. The Arduino SHT20 waterproof temperature & humidity sensor adopts dual waterproof protection techniques. 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 submerge 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 the microcontroller such as Arduino. We recommend DFRobot Gravity 4Pin Sensor Adapter convenient.  Sensor Interface: Red VCC Green GND Black SDA White SCL     SPECIFICATION     Operating Voltage: 3.3/5V Communication Interface: I2C / IIC Protection Class: waterproof anti-condensation RH Response Time: 8s (tau63%) Accuracy: ±3% RH / ±0.3 ℃ Measuring Range: 0-100% RH / -40-125 ℃ Dimension: 73mm * 17mm / 2.87 * 0.67 inches Weight: 44g     DOCUMENTS   Product WIKI SHT20 Datasheet
