WDS308 Dust Monitor sensor
WDS308 integrated dust monitoring sensor is a miniature instrument mainly used in smart cities, smart lamp poles, and smart construction sites to monitor meteorological environmental elements.The equipment system is modular in design, and users can flexibly configure it according to their needs. It can integrate solar power supply system, LED display screen and GPRS wireless transmission module, etc。
Measurement technology:
Integrated structure, a single device synchronously collects parameters such as temperature, humidity, air pressure, wind speed, wind direction, rainfall, radiation, UV, PM2.5/10, noise, etc.
Producthighlights:
Support -20℃~+80℃ wide temperature measurement, 0~75m/s strong wind monitoring and 0~24mm/min rainfall measurement range, adapt to extreme climate scenarios
Transmission mode:
RS485, RS232, SDI12, 4-20mA, 0-5V optional; support ASCII code and Modbus protocol
Advantages of Dust Monitor WDS308
1. Industrial-grade chip: MEMS working principle realizes miniaturization and high precision (such as air pressure sensor resolution 0.1hPa)
2. Transmission mode: RS485, RS232, SDI12, 4-20mA, 0-5V optional; support ASCII code and Modbus protocol
3. Modular design to customize parameter combinations on demand
4. IP66 protective shell, service life 10 years
5.Power consumption ≤0.4w; optional solar energy, mains electricity; can be installed on a hollow mast with a diameter of 60mm-75mmφ, tripod
Green transformation of construction sites
The construction site is located in the city center, surrounded by residential areas, schools and commercial places.The WDS306 dust monitoring sensor is used to monitor atmospheric temperature and humidity, air pressure, wind speed and direction, PM2.5/10, noise and other data. The construction period is expected to be two years, covering various building types such as residential and commercial complexes.In the early stage of construction, the surrounding environment was affected to a certain extent due to the dust problem. In order to improve the construction environment and reduce dust pollution, the construction party decided to introduce dust meteorological sensors and supporting monitoring systems。
Shijiazhuang Institute of Information Technology Assembly Smart Site Monitoring
Hebei Shijiazhuang Information Engineering Vocational College deployed environmental monitoring equipment during the construction phase to collect real-time data such as PM2.5/10, wind speed and direction, and noise, and linked it with the sprinkler system.When the PM concentration exceeds the standard, the fixed fog cannon, mobile fog cannon vehicle and tower crane spray device will automatically start, combined with the enclosure spray to form a “five-layer protection” system to control dust within the construction area。
