The SHT20 I2C temperature & humidity sensor adopts Sensirion techniques. The humidity sensor is a capacitive type and the temperature sensor uses a band gap.The 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 the surrounding environments temperature and relative air humidity precisely.
The 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. The sensor won't be damaged even after a long time submerged in 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 LSN50v2 as well as other custom applications.
