Product Description
SHT21 Humidity Temperature Sensor
VOTESEN VTH Temperature and Humidity Sensor
VOTESEN VTH series SHT 21 digital temperature and humidity module adopts high precision SHT series sensor equipped with a high quality filter shell for large air permeability, fast gas humidity flow and exchange rate. The shell is 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.
VTH probe is equipped with a 10K pull-up resistor and a 1uF filter capacitor. The sensor is fully digital and multi-point
calibrated, with high accuracy, good consistency, long-term stability, low drift, and full temperature compensation for humidity.
The surface of the sensor is covered with a waterproof and breathable membrane to protect it, even if it is immersed in
electricity for a long time, it will not damage the sensor.
There are different types of probe to select and customize the sensor based on your working environment needs.
A. Copper Sintered Protective Cover Probe
The protective cover is nickel-plated after sintering copper particles, which has the characteristics of breathability, high temperature resistance, and corrosion resistance, which improves the life of the sensor. The wiring part uses an aviation plug for quick installation and removal.
B. PE Waterproof Protective Cover Probe
* Optional yellow hexagonal connector or silver round connector.
* The waterproof head material uses a polymer PE sintered filter element, which is waterproof and removes dust, and buffers high-speed flowing gas. The temperature and humidity measurement results are more stable and accurate. It is suitable for soil, outdoor rain, high temperature agricultural greenhouses surroundings.

Product FAQ
Q: What is the common use of a Temperature and Humidity Sensor?
A: Temperature and Humidity sensors are among the most commonly used environmental sensors. It is widely use to provide the actual humidity condition within air at any given point or in any given place. Such devices are commonly used in situations in which air conditions may be extreme or where air conditions need to be controlled due to varying reasons.
Q: Why is Temperature and Humidity Sensor important in some of the industries?
A: Humidity is the presence of water within the air. Measuring humidity within the environment can be critical due to the fact that the higher the humidity, the warmer it may seem. In industries, humidity measurement is often important because it can affect the health and safety of personnel as well as the cost of the product. As a result, temperature and humidity sensors are often quite important.
Q: How do I choose a suitable Temperature and Humidity Sensor?
A: There are a some important specifications you might need to consider when you choosing this product. This includes:
* Accuracy
* Long-term stability
* Ability to recover from condensation
* Resistance to physical and chemical contaminants
* Interchangeability
* Repeatability
