4G / WiFi/RS485/LoRa/NB Wireless CO2 Sensor

4G / WiFi/RS485/LoRa/NB Wireless CO2 Sensor

1  Product Overview

 DAQ-GP-CO24G wireless infrared carbon dioxide sensor terminal is a wireless carbon dioxide concentration measurement product launched by Shanghai Data Acqisition IOT  Technology Co., LTD. Principle: This product uses the non-dispersive infrared (NDIR) principle to detect CO2 present in the air. Since different kinds of gases absorb specific wavelengths of infrared light, the relationship between gas concentration and absorption intensity (Lambert-Beer law) is used to identify gas components and determine their concentration, which has the advantage of being less susceptible to environmental interference than chemical sensors.

The equipment is mainly composed of infrared light source, optical path, infrared detector, optical sensor composed of software algorithm and its supporting wireless transmission protocol processing part. This product can be widely used in gas pipeline, intelligent agricultural breeding, chemical plants, production workshops and other fields of carbon dioxide concentration monitoring.

By default, the sensor terminal supports 4G/WiFi/LoRa and other communication methods, and supports MQTT, HTTP and other communication methods, which can overcome the wireless communication block caused by the special environment on the site, greatly simplifying the field deployment time and reducing construction costs.

5Data Reporting Communication Protocol5.1  Protocol Parsing Instructions

For UDP / TCP / MQTT / HTTP and other push methods, users should provide the public network IP (or domain name) address and port number of the cloud server to receive the data.

Example of JSON format:

{"CO2":731,"ID":"860344048491162"}

Message analysis:

{

"CO2": 731, / / CO2 gas concentration value, unit in ppm

"ID": "860344048491162" / / Device ID

}

5.2  Agreement Customization

If you need to customize other communication protocols, you can contact the business personnel to communicate them.

6.Platform Docking6.1 Default Platform

The product is connected to our designated industrial Internet of Things platform by default, and the platform interface is as follows:

Computer-side browser interface

Mobile terminal WeChat access interface

6.1  The User Specifies the Platform

Take the connection of Ali Cloud platform as an example. After users create products and add devices on the Ali Cloud Internet of Things platform, users need to provide a triad: {ProductKey, DeviceName, DeviceSecret} and the MQTT theme to be released.

For example, the value of triples is:

ProductKey = b0FMK1Ga5cp

DeviceName = 862991419835241

DeviceSecret = y7MTCG6Gk33Ux26bbWSpANl4OaI0bg5Q
