APPLICATIONS

Environmental Measurement

The environment has a significant impact on our health, comfort, and productivity. Aosong Electronics Co., LTD (shortly called ASAIR) sensor solution provides detailed and reliable data on key environmental parameters, such as temperature, humidity, VOC,CO2. Environmental sensing opens up new possibilities for a variety of applications, creating smarter devices to improve our comfort, health and energy efficiency.
 
Ambient temperature and humidity
 
Thermal comfort is an important factor in the temperature and humidity control system. Under what conditions will people feel comfortable or uncomfortable, and under what circumstances will the environment harm human health? At this point, relative temperature and humidity play a key role, so you can improve your health by using a temperature and humidity sensor. The best working temperature is 22~25 degrees Celsius. Scientific research shows that work efficiency is reduced under 22 degrees Celsius and people will will be sleepy over 25 degrees Celsius. So it is necessary to adjust the temperature of the air conditioning office to avoid the temperature too high or too low.

The best foot soak temperature is: 38 ℃~45 ℃.

The best working temperature is 22℃~25 ℃.
The best temperature for a bath is 35 ℃~40℃.
The body's comfortable sleep temperature is 20℃.
The best face washing temperature is 20 ℃ to 38 ℃.
The best eating temperature is 35 ℃~ 50 ℃.
The best hair washing temperature is: 36 ℃~40 ℃.
The optimum drinking water temperature is: 18 ℃~45 ℃.
The best brushing temperature is 35 ℃.
   
Volatile organic compounds (VOC)

The widespread use of new products and building materials has led to increased concentrations of indoor pollutants, in particular volatile organic compounds . It is well known that many of these compounds can damage health and reduce productivity, for example, headaches, Eye irritation or dizziness. The ASAIR gas sensor solution can monitor these indoor air pollutants to help manufacturers develop new smart home and HVAC applications. 
 
Carbon dioxide (CO2)

Carbon dioxide is a key indicator of indoor air quality. Houses have become more energy-efficient because of new energy standards and better insulation, but air quality is deteriorating rapidly. ASAIR sensor solutions can provide accurate and stable monitoring for CO2 , temperature and humidity, enabling customers to develop new solutions to improve energy efficiency while taking into account human health.

Brief introduction of temperature and humidity Sensor


Since temperature and humidity are closely related to both physical quantities themselves and real people's lives, The temperature and humidity sensor is a device or device that can convert temperature and humidity into electrical signals that can be easily measured and processed. Measure temperature and relative humidity.


The digital signal temperature and humidity sensor is divided into two kinds of programs: single bus and IIC bus.


Temperature:  a physical quantity that measures the cooling and heat of an object, one of the seven basic physical quantities in the international system of units. In production and scientific research, many physical phenomena and chemical processes are carried out at a certain temperature. People's lives are also closely related to him.


Humidity:  humidity has been closely related to life a long time ago, but it is difficult to express by quantity.


The most commonly used physical quantity of humidity in daily life is the relative humidity of air. Expressed by RH, the relative humidity is closely related to temperature in the derivation of physical quantities. The higher the temperature of a certain volume of airtight gas, the lower the relative humidity. The lower the temperature, the higher the relative humidity.


Some definitions of humidity:


Relative humidity:  in the Metrology Act, humidity is defined as "the quantity of the image state". The humidity in everyday life is relative humidity, expressed in RH%. The percentage of the amount of water vapor (vapor pressure) in a gas (usually in air) that is saturated with the amount of water vapor (saturated vapor pressure) in the same condition as its air.


Absolute humidity:  refers to the amount of water vapor actually contained in air per unit volume, generally in grams. Temperature has a direct effect on absolute humidity. In general, the higher the temperature, the more water vapor, the greater the absolute humidity; on the contrary, Absolute humidity is small.


Saturation humidity:  the maximum amount of water vapor that can be contained in the air at a given temperature per unit volume. If the excess water vapor exceeds this limit, the excess water vapor will condense and become water droplets. The saturation humidity of air is not fixed, it changes with the change of temperature. The higher the temperature, the more water vapor can be contained in the unit volume of air, and the higher the saturated humidity is.


Dew point:  refers to air containing a certain amount of water vapor (absolute humidity), when the temperature drops to a certain degree, the vapor is saturated (saturated humidity) and begins to liquefy into water. This phenomenon is called condensation. The temperature at which the steam begins to liquefy into water is called the dew point. If the temperature continues to fall below the dew point, the supersaturated water vapor in the air condenses into water droplets on the surface of the object. Wind is closely related to the temperature and humidity in the air, and it is also one of the important factors affecting the change of air temperature and humidity.
