Humidity, Moisture Sensors: SHT71

The SHT71 is a humidity and temperature sensor produced by Sensirion. The SHT71 is a highly accurate device that is small in size, has excellent long-term stability, and is easy to install and use. These features make it a popular choice for many applications.

Application Fields

The SHT71 can be used in a variety of applications including indoor climate control, automotive climate control, medical equipment, air quality monitoring, and industrial automation. It is capable of providing accurate readings from -40 to 125 degrees Celsius, making it a viable option for a wide range of applications.Indoor climate control is one of the most common applications of the SHT71, as it can be used to measure the humidity and temperature of an environment. This information can be used to regulate the indoor temperature, protect against mold growth, and increase energy efficiency.Automotive climate control is also a popular application of the SHT71, as it can be used to monitor and adjust the temperature and humidity of a car\'s interior. This can help to improve comfort levels for passengers, reduce the need for air conditioning, and extend battery life.The SHT71 is also used in medical equipment such as oxygen level monitors and body temperature monitors. Its accuracy and stability make it an ideal choice for these applications.Air quality monitoring is another application of the SHT71, as it can be used to measure levels of air pollution. The SHT71 is capable of measuring humidity and temperature, both of which can be indicators of air quality.Finally, the SHT71 can be used in industrial automation for monitoring the environment of industrial settings. It can be used to monitor temperature, humidity, and other factors, allowing for safer and more efficient operation.

Working Principle

The SHT71 works by using capacitive humidity sensing. In order to measure humidity, the SHT71 uses two electrically conductive plates which are separated by a polymer film. When the surrounding air has a higher humidity, the polymer film absorbs moisture and swells, causing the gap between the two plates to become larger. This change in the gap size is measured by the SHT71 in order to calculate the humidity.The SHT71 also uses metal oxide sensing to measure temperature. When exposed to different temperatures, the resistance of a metal oxide material changes. The SHT71 measures this change in resistance and converts it into a temperature reading.

Conclusion

The SHT71 is a small and accurate humidity and temperature sensor which is used in a variety of applications. It can be used in indoor climate control, automotive climate control, medical equipment, air quality monitoring, and industrial automation. It uses capacitive humidity sensing and metal oxide sensing to measure humidity and temperature, respectively.
