SHT20 PE probe humidity temperature sensor digital I2C output
Votesen PE Probe 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, PE Probe VTH200 temperature humidity sensor is CE and ROHS certified.
There are different types of PE probes. The PE Standard Probe is the most cost effective humidity temperature sensor. On the other hand, the PE Enhanced Probe has a better Stainless Steel filter in the probe. The PE probe is widely use in greenhouse, outdoor, construction site such as Concrete Test Block Inspection. For some of your working environments, you might need a probe holder to support and to fix the position of the humidity temperature sensor. You can customize the humidity temperature sensor based on your working environment.
