Sensirion SHT2x Digital Humidity Sensor I2C Output for Greenhouse Agriculture
Votesen VTH200 digital humidity temperature module adopts high precision Sensirion SHT2x sensor equipped with a high-quality filter shell for large air permeability, fast gas humidity flow and exchange rate. The shell is waterproof and will keep water from seeping into the body of the sensor and damaging it, but allows air to pass through so that it can measure the humidity (moisture) of the environment.
Sensirion SHT2x shows better reliability and long-term stability. They are an industry standard, widely used humidity and temperature sensor. Humidity is measured using a capacitive sensor while temperature is measured using a band-gap sensor. You can choose the most suitable chip for your application: SHT20 - Low cost, SHT21 - Standard, SHT25 - High Accuracy. VTH200 with SHT2x can measure surrounding environment temperature and relative air humidity precisely. Most importantly, VTH200 humidity temperature sensor is CE and ROHS certified.
