Over the past few years, with the rapid development of my country’s economy and the continuous expansion of urban construction, various pollutants have been entrained in the air to varying degrees. Harmful substances have been discharged into the air, changing the composition of the air and forming Air pollution. On the other hand, it is the continuous optimization and adjustment of the layout of urban functional areas and industrial structure. Many cities have undergone great changes in the urban environment, the scale of urban built-up areas, and the number and distribution of population. The original urban environmental air monitoring points The locations are lacking in quantity or unscientific in spatial distribution, and cannot continue to meet the technical requirements of urban ambient air monitoring, thus facing the need for optimization such as continuous addition or adjustment.
In order to solve the problem of air pollution, various cities have built air quality monitoring points to grasp the laws. However, because the data of the fixed monitoring points are not completely accurate, and affected by the wind direction and the location of the monitoring points, the monitored data cannot fully represent the real air quality situation, and with the increasing demand for air quality monitoring, a simple fixed monitoring The overall cost required to do so will gradually increase.
The remote air quality detector-AS51 provided by Gongshou.com can not only detect PM2.5. It can also detect CO, NO, NO2, O3, CO2, air temperature and humidity in the air. And can be tracked in real time, and can see changes in air quality at any time. A key aspect of this tester is to focus on sustainability and energy saving through building construction practices.
Remote Air Quality Detector-The precise electrochemical sensor (Alphasense A4 series) in AS510 can monitor CO, NO, NO2, and O3 gas at ppb level. If necessary, other gases (such as SO2) can also be detected. In addition, the high-sensitivity GPS module can accurately locate and measure the area to be detected. Even in buildings, the RMS-based detector has strong anti-interference ability. The sampling rate is on average every 20 seconds, every 15 Transfer data in minutes. This can also be set for different applications.
Remote Air Quality Detector-AS510 communicates with remote database via GPRS. These include storage and previous real-time data when network wires or temporary overloads. Of course, this unit needs SIM card service, which can be provided by Atmospheric Sensors or other suppliers. It is worth noting that the local 16G SD card of the remote air quality detector-AS510 is for expansion storage, and the test results are transmitted via GPRS in order to restore and serve as a data backup. So as to collect more complete data. Among them, his laser optical particle counter (Alphasense) can detect PM1, PM2.5, PM10, etc. and quickly detect air quality parameters, which is convenient and fast, and plays an important role in daily air quality monitoring.
The AS510 air quality monitor is emphasized because it can be installed on the wall and directly connected to the return duct of any air system. When monitoring the particle level in the indoor space, the sensor communicates with the motor controller of the ventilation or filtration system to adjust the motor speed and limit energy consumption according to the demand and the detected particle level.
The powerful communication and connectivity of remote air quality detectors make them very easy to use, using multiple protocols and rich register mapping to control and communicate with most PLCs and building automation systems. These instruments can provide excellent closed loops on any system The control function is even compatible with the Internet of Things.
