Product Details

1 Product Overview

DAQ-GP-CL4G cleanliness monitoring terminal is a multi-function particle counter based on 4G wireless transmission, launched by Shanghai DAQ IoT Technology Co., Ltd. It draws an air sample through a built-in air pump, and a built-in microprocessor then calculates the number of particles of different sizes. It can collect dust particle counts, temperature and humidity, dew point, and wind direction/speed data in the environment.

The cleanliness monitor supports 4G/WiFi/RJ45 communication. It is simple and convenient to operate, with a clear and intuitive interface. It has a built-in lithium battery and a standard Type-C charging port, making it easy to carry. It is suitable for environmental air quality detection in authoritative institutions such as blood centers, CDC centers and quality supervision institutes, as well as production enterprises and research departments such as pharmaceutical workshops and semiconductor workshops.

6 Communication Protocol

6.1 Protocol Parsing Description

Multiple push methods such as TCP/MQTT; users receiving data must provide the public IP (or domain name) address and port number of the cloud server.

Example JSON data message:

{“flag0.3”:51707.00,“flag0.5”:9214.00,“flag1”:622.00,“flag2.5”:56.00,“flag5”:16.00,“flag10”:0,“tmp”:16.75,“humi”:26.28,“dp”:-2.78,“diff”:-0.01,“ID”:“30204BR221TODE88”}

Message parsing:

{

“flag0.3”:51707.00, // number of 0.3μm particles

“flag0.5”:9214.00, // number of 0.5μm particles

“flag1”:622.00, // number of 1μm particles

“flag2.5”:56.00, // number of 2.5μm particles

“flag5”:16.00, // number of 5μm particles

“flag10”:0, // number of 10μm particles

“tmp”:16.75, // temperature value

“humi”:26.28, // humidity value

“dp”:-2.78, // dew point value

“diff”:-0.01, // differential pressure value

“ID”:“30204BR221TODE88” // device ID

}

6.2 Protocol Customization

If you need to customize other communication protocols, please contact our sales staff.

7 Platform Integration

7.1 Default Platform

By default, the product connects to our designated open industrial IoT platform, whose interface is shown below:

PC browser interface

Mobile access interface

7.2 User-Specified Platform

Taking Alibaba Cloud platform integration as an example: after the user creates a product and adds a device on the Alibaba Cloud IoT platform, the user needs to provide a triple {ProductKey, DeviceName, DeviceSecret} and the MQTT topic to publish to. For example:

ProductKey = b0FMK1Ga5cp

DeviceName = 862991419835241

DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q
