The DL-1000 is a series of particle and gas measurement module that can measure the concentration of aerosols such as PM1, PM2.5, PM10 and the number of particles (0.3μm, 0.5μm, 1μm, 2.5μm, 5μm, 10μm) in the air. In addition, a variety of fume concentrations, such as TVOC which may be harmful to human health can also be measured. DL-1000 can trigger an alarm when the concentration is too high. It can be used to record PM1/2.5/10, TVOC, temperature, humidity and dew point data, including date and time stamps, and is able to store up to 180,000 downloadable records. Real-time data can be accessed from the DL-1000 series Data Logger from anywhere and at any time by using the free Windows software, the iOS App or the Android App, as long as it is connected to the same local network as the Data Logger being connected to. Popular industrial protocols such as DCON, Modbus RTU, and Modbus TCP, as well as the emerging machine-to-machine (M2M)/IoT (Internet of Things) connectivity protocol - MQTT are supported. The DL-1000 series Data Logger can be connected via widely used communication interfaces including RS-485, Ethernet and PoE, meaning that the device can be easily integrated into existing HMI or SCADA systems, and is easy to be maintained in a distributed control system. The DL-1000 series provides IP43 grade protection approval and is designed for industrial applications in harsh environments. The rugged RJ-45 ensures tight, robust connections, and guarantees reliable operation, even for applications that are subject to high vibration and shock.

Supports the MQTT Protocol for IoT Applications Features

Multi-platform Remote Access Software
Real-time data from the DL-1000 data logger can be accessed from anywhere and at any time by using the iAir Utility, the iOS or Android App, or via a regular web browser, as long as they are connected to the same local network as the data logger being connected to.

The iAir Utility is a powerful tool that is designed for configuring the modules, monitoring real-time data, grouping DL-1000 modules to view and manage the status of distributed groups. It can also perform downloading of the log data, and then the data can be exported to a CSV file and further being imported into any industry standard software or spreadsheet for analysis.
 

In smart city applications, the smart street lighting system usually integrates a variety of communication technologies and have evolved beyond just providing illumination. In recent years, the construction of high-density street lighting has become one of the most important sources for government to collect environmental information around the road. DL-1000 series products feature standard industrial communication protocol - Modbus RTU/TCP, and can be integrated with smart streetlights to achieve outdoor air quality monitoring such as monitoring of: O3, CO, CO2, SO2, NO2, TVOC, HCHO, and Particle Matter 1/2.5/10. Due to the accumulated aerosol may be kept around the sensor and potentially lead to sensor blockages and result in incorrect recordings over time, DL-1000 supports replaceable dust filter patch to easily change the patches inside the filter hood without the need to uninstall the device for replacement.
