Everyone may no stranger to the temperature and humidity when it is mentioned. While we wake up in the morning, we turn on the forecast via our phone and see today’s temperature and humidity data. On the way to work, the temperature and humidity data also be displayed show scrolling in the subway station or the bus. So how can we measure these data? That must mention our temperature and humidity sensor.
Temperature and humidity sensor is equipment or device that can convert temperature and humidity into an electrical signal which can be easily measured and processed. The market’s temperature and humidity sensor usually used to measure temperature and relative humidity. Relative humidity refers to the humidity in the daily life, expressed as RH%. It is the percentage of the amount of water vapor (vapor pressure) contained in a gas (usually air) that is equal to the amount of saturated water vapor pressure (saturated vapor pressure) in the air.
Sometimes we will mention the dew point sensor in production. Dew point sensor, one of the temperature and humidity sensors, is a dew point meter. It is an instrument that can directly measure the dew point temperature. It is an air containing a certain amount of water vapor (absolute humidity). When the temperature drops to a certain level, the water vapor in it reaches saturation (saturation humidity) and begin to liquefy into water. This phenomenon is called condensation. The temperature at which water vapor begins to liquefy into water is called the dew point temperature for short.
And how to collect the temperature and humidity signals? The temperature and humidity sensor mostly uses temperature and humidity one-piece probe as a temperature element to collect the temperature and humidity signals. After voltage stabilizing filter, operational amplification, nonlinear correction, V/I conversion, constant current and reverse protection and other circuits processing converted into a linear relationship with temperature and humidity current signal or voltage signal output, can also be directed through the main control chip 485 or 232 interface output. Temperature and humidity sensor probe housing play an important role in the chip protection. To measure soil temperature and humidity, a probe is inserted into the soil to measure. By this time the waterproof and dustproof ability of probe housing becomes essential.
HENGKO temperature and humidity sensor housing is sturdy and durable, safe and effective protection of PCB module from damage, dustproof, anti-corrosion, IP65 waterproof grade, more effectively protect humidity sensor modules from dust, particulate pollution, and oxidation of most chemicals, to ensure its long-term steady work, close to the sensor theory life. We also add waterproof glue to PCB module and more effectively prevent water from infiltrating into the PCB module causing damage.It can be used in all kinds of high humidity measurement
With the development of technology, the industry for temperature and humidity sensor requirements are increasingly high. HENGKO has 10 years of OEM/ODM customized experiences and collaborative design/ aided design ability. Our professional design team can provide technical support for your high standards. We have more than 100,000 product sizes, specifications and types for your select, customized processing of a variety of complex structures of the filter products also available.
