Votesen VTH200 digital humidity temperature module adopts high precision Sensirion SHT20 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. It has been widely used in HVAC, consumer goods, weather stations, test & measurement, automation, medical, humidifiers, especially perform well in an extreme environment like acid, alkali, corrosion, high temperature and pressure. Most importantly, VTH200 temperature humidity sensor is CE and ROHS certified.
