Product Description
Temperature and humidity sensors usually consist of a temperature sensor and a humidity sensor. They can convert the physical quantities of temperature and humidity in the environment into electrical signals for measurement, display, and control. Temperature sensors generally operate based on principles such as thermistors, thermocouples, and semiconductors. They measure temperature by sensing changes in parameters such as resistance and voltage caused by temperature changes. Humidity sensors, on the other hand, utilize the sensitive characteristics of humidity - sensitive materials, such as capacitive, resistive, and ceramic types, to convert humidity changes into corresponding electrical signal outputs.
Product Features:
High Precision: They can accurately measure environmental temperature and humidity. Generally, the temperature measurement accuracy can reach ±0.1°C - ±1°C, and the humidity measurement accuracy can reach ±2% - ±5%RH.
Wide Measurement Range: The temperature measurement range usually extends from - 40°C to 125°C or even wider, and the humidity measurement range can cover 0% - 100%RH.
Fast Response: They can quickly sense changes in environmental temperature and humidity and promptly output corresponding electrical signals. The response time is generally between a few seconds and tens of seconds.
Good Stability: They have good long - term stability, can maintain accurate measurement performance under different environmental conditions, and have strong anti - interference ability, being less susceptible to factors such as electromagnetic interference and vibration.
Small Size and Light Weight: They are convenient for installation and integration into various devices and systems without taking up too much space.
Multiple Output Forms: There are analog outputs (such as voltage and current) and digital outputs (such as I2C, SPI, RS485 interfaces), which can be easily connected to different control systems and instruments.
Temperature and humidity sensors are used in a wide variety of applications:
Meteorology: Used in weather stations, etc., to provide temperature and humidity data.
Industry: Ensure suitable production environments in industries such as electronics and chemicals.
Agriculture: Assist in environmental regulation in greenhouse farms and livestock farms.
Home: Achieve temperature and humidity monitoring and control in smart homes.
Medical: Ensure that the temperature and humidity in various hospital areas meet the standards.
Warehousing: Protect precision instruments, cultural relics, and other items in warehouses.
