This temperature & humidity sensor is equipped with waterproof probe. It comes with the 4C CMOSens®  temperature & humidity sensor chip and the probe has gone through dual waterproof protection test.
The temperature & humidity sensor adopt Sensirion techniques. Except the humidity sensor of capacitive type and the temperature sensor of band gap ,  contains an amplifier, A/D converter, OTP memory and a digital processing unit. Compared with early SHT1x series and SHT7x series,  shows a strong reliability and long-term stability. It can measure surrounding environment temperature and relative air humidity precisely.
The Arduino 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.
