1 Product Overview

DAQ-GP-PT100 wireless industrial temperature sensor transmitter terminal is a wireless temperature measurement product for industrial field launched by Shanghai Data Acquisition Technology Co., LTD. This product converts the thermocouple and thermal resistance signals into input electrical signals or measured temperatures and reports the data regularly in 4G/LORA and other ways. As a new generation of temperature measurement data cloud products can be widely used in metallurgy, petrochemical, electric power, light industry, textile, food, national defense and scientific research and other industrial sectors.

The sensor terminal supports 4G/NB-IOT/LoRa/WiFi communication mode (NB-IOT/LoRa communication mode is used by default for battery power supply), which overcomes the wireless communication block caused by the special environment of the site, greatly simplifying the site deployment time and reducing construction costs. This terminal can support up to 8 channels of temperature acquisition, with pt100 temperature probe shape variety, wide measuring temperature range, high measuring accuracy, easy to install.

5 Data Reporting Communication Protocol

5.1 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:

{"T":56.72,"ID":"860344048491162"}

Message analysis:

{

"T": 56.72, // The temperature of the first channel

"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.本产品订单满2000元，免费定制通信协议。

6 Platform Docking

6.1 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

6.2 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

7 Application Cases

Equipment operating temperature monitoring
