Indoor air quality detector
Before we use an instrument, it is very necessary to understand its working principle, because its principle determines its use method and some functional characteristics. Indoor air quality detector is an instrument used to judge the quality of gas. Its response speed is relatively fast, which can help us know the air quality in an environment in time. Since some users are not particularly familiar with the working principle of the air quality detector, let me briefly introduce it to you below.
Indoor air quality detector working principle
Indoor air quality detector is relatively common in our daily life. It can detect various parameters such as formaldehyde, PM2.5, TVOC and temperature and humidity in real time. The instrument adopts a compact design, which is small and exquisite, and is easy for users to carry. The gas concentration is detected by the sensor, which can accurately measure the concentration of polluting gas, and quickly calculate the air quality index AQI. If the concentration in the current environment exceeds the standard, it will immediately alarm. The working principle of the air quality detector is to use Formaldehyde sensor, PM2.5 sensor, TVOC Sensor, Temperature & Humidity Sensor and other devices to inhale the gas into the instrument and amplify the weak signal collected by the sensor through the operational amplifier, and then remove some noise interference. After processing by special technology, the measurement data can be displayed on the screen in real time.
It can be known from the above that the working principle of the Indoor air quality detector is mainly realized through sensors. When detecting different types of gases, different sensors should be selected, so as to ensure that the obtained measurement results are accurate. Due to the good detection performance of the air quality detector, its application field is relatively extensive.
Indoor air quality detector application:
The air quality detector is mainly suitable for ambient air monitoring institutions, gas detection centers, environmental management companies, decoration companies, construction companies, workshops, factories and mines, or some instruments with special functions can be used in scientific research, teaching, laboratories and other industries.
In addition, the air quality detector can also be used in living rooms, offices, hotels, restaurants, shopping malls and other places where air quality needs to be tested. Because it is a portable instrument, it is easy to move and apply, and the testing location can be changed at any time.
The air quality detector measures various gases in the air through its sensors, and then can display the detection data on the screen through some methods, and it can also be used in a wide range of fields to help users quickly know the air quality in the current environment.
