With the continuous penetration of the concept of sustainable development, the development concept of "prevention first and governance as supplement" for the environment has gradually been accepted by all walks of life, and more accurate and real-time technologies have been gradually adopted in the field of environmental monitoring to achieve Accurate monitoring of the environment to prevent environmental pollution.
Fugitive dust online monitoring system, also known as fugitive dust detector, online environmental monitoring system, etc., is currently a mainstream device used to monitor various environmental parameters, often involving noise, temperature, humidity, PM2.5, PM10, wind speed The collection of environmental parameters such as, wind direction, etc. is suitable for on-site real-time data online monitoring of various construction sites, road construction, tourist attractions, residential areas, large commercial circles, industrial parks, etc. Through the real-time monitoring of atmospheric pollutants and environmental meteorological conditions, combined with the latest technologies such as big data and cloud computing, the simulation and analysis of the atmospheric pollution process can achieve regional pollutant monitoring and early warning; support the linkage of dust suppression equipment to achieve active and intelligent dust reduction, In order to achieve targeted prevention and control.
On construction sites, dust pollution is very serious. As we all know, the detection of particulate matter is a must-have for the dust detector. The first parameter to be tested will not be introduced here. However, the monitoring of temperature and humidity on the construction site cannot be ignored, and we will introduce it in detail here.
Some people may have questions: Why do we need to monitor the temperature and humidity on the construction site? Here, a brief list:
- Temperature and humidity monitoring provides protection for the personal safety of workers. The construction site is a high-intensity workplace. Workers consume a lot of labor. Too low or high temperature or humidity may affect the mental state of the workers during operation. A little distraction may result in injury or even damage to life and safety. Therefore, it is very important to monitor the temperature and humidity on the construction site. The temperature and humidity in the environment can be monitored at all times, and the temperature and humidity can be adjusted in time to maintain the comfort of the construction site. In addition, if the temperature is too high, the foreman can notify the workers in time. Good heatstroke prevention and sun protection measures, and staff can also be arranged to make some mung bean soup for heatstroke prevention and thirst quenching to prevent workers from heatstroke. It can not only improve work efficiency, but also effectively protect the personal safety of workers.
- Temperature and humidity monitoring also plays an important role in the storage of building materials. Generally, construction sites will purchase a large number of building materials, which cannot be used up all at once. Each material has its own suitable storage conditions. Once the temperature and humidity are too low High, it may cause the deterioration of the material.
- Many construction operations also have requirements on temperature and humidity, and suitable operating environmental conditions are conducive to the quality assurance of this process.
There are also requirements for the selection of temperature and humidity sensors in the dust online detector. The construction site environment is generally harsh, especially when there is a lot of dust. The editor recommends a dust-proof and waterproof temperature and humidity sensor module-HCPV-201W-01 , This is a sensor module that integrates temperature and humidity based on the humichip chip independently developed by South Korea’s Samsung. It has a PTFE filter to prevent damage from dust and moisture; it meets the strict automotive standard AEC-100, long-term stability and Reliability is guaranteed; the sensor outputs the temperature-compensated humidity value through a linear voltage, which can be directly connected to a microcomputer with ADC input, and the temperature output (only for HCPV-201) is directly output by the NTC thermistor. , Can be directly connected to a microcomputer through ADC input, which is convenient to use; ultra-low power consumption, energy saving and emission reduction, has been adopted by many domestic companies that do dust detection systems, and the response is very good.
In use, HCPV-201W-01 can directly replace the HTG3500 series of temperature and humidity sensors of French humirel with PIN to PIN, such as HTG3515CH, HTG3535CH, their pin distribution and definition, output are almost the same, the hardware does not need to be changed, because the two models The NTC thermistors used are not the same model, so the temperature output resistance values are slightly different, and they can be replaced with each other by simply modifying the software.
