How does Air quality monitor achieve 24-hour unattended operation?

Air quality monitor can simultaneously monitor elements such as negative oxygen ions, PM2.5, PM10, temperature, humidity, air pressure, oxygen content, noise, wind speed, and wind direction. It is suitable for forestry, scenic areas, parks, environmental protection, meteorology, agriculture, and other fields, providing 24-hour uninterrupted real-time monitoring and supporting data storage, analysis, printing, and multiple alarm methods.

Air quality monitor is a real-time environmental meteorological monitoring and dissemination system used in forestry, scenic areas, parks, environmental protection, meteorology, agriculture, and other fields. This system primarily focuses on centralized monitoring and management of air quality in scenic areas and parks. It is an automated monitoring system capable of unattended operation and 24-hour uninterrupted real-time monitoring and recording. The system can monitor and record air quality over large areas and transmit data to a PC in real time.

Air quality monitor monitors elements including negative oxygen ions, PM2.5, PM10, temperature, humidity, air pressure, oxygen content, noise, wind speed, and wind direction. The negative oxygen ion monitoring system employs a cylindrical electrode aspiration method, using a high-voltage electric field to ionize air molecules and detect negative ion concentration. PM2.5 and PM10 are measured using laser scattering. Meteorological elements such as temperature, humidity, and air pressure are detected using diode junction voltage method, capacitive method, and piezoresistive method, respectively. Wind speed and direction are measured using ultrasonic principles. The system features a modular design, with interchangeable sensors and comes standard with a professional mounting bracket, allowing for wall or column mounting and convenient operation and maintenance.

Data is transmitted in real-time to a PC for storage and analysis using monitoring software, which can output and print historical data and graphs. The system supports multiple alarm methods, including on-site audible and visual alarms, telephone alarms, SMS alarms, and network client alarms. The system automatically issues an alarm when monitored data exceeds a set threshold. Users can view and analyze data through data management software, and archive and print charts or reports. The system supports remote data viewing via cloud platform, web, and WeChat official account.

The Air quality monitor system can be widely used in ecological parks, wetland parks, waterfall parks, and forest parks across various regions. In the ecotourism sector, it can be deployed in scenic areas and forest parks to display real-time negative oxygen ion concentrations, providing data support for "natural oxygen bar" certification. The system supports sensor expansion; sensors with 485 interfaces and Modbus protocols can be used directly. The system has been partnered with thousands of parks and scenic areas, demonstrating stable backend operation and a low failure rate. The entire unit features lightning protection, making it suitable for long-term outdoor use.
