1  Product Overview

SC-GP-CT01 wireless current and temperature acquisition sensor terminal is equipped with low power consumption and high sensitivity of the open type transformer, through the principle of electromagnetic induction, the primary side of the large current into the secondary side of the small current, and then used for current monitoring, can be very sensitive to detect the size of the line current, and at the same time to the designated platform server wireless report data regularly.

The sensor terminal supports 4G/NB-IOT/LoRa/WiFi communication mode (the battery power supply adopts NB-IOT/LoRa communication mode by default), which overcomes the wireless communication block caused by the special environment on the site, greatly simplifying the field deployment time and reducing the construction cost. This terminal can support up to 8 current acquisition, with a wide range of open and close transformers, high quality magnetic core materials, open and close structure, easy to install, used for AC motors, lighting equipment, air compressors, heating ventilation and air conditioning devices, building self-control system, industrial urban network, rural power grid renovation projects and other scenes of current monitoring and acquisition.

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:

{"A":56.7,"B":55.8,"C":49.3,"D":1.2,"deviceID":"860344048491162"}

Message analysis:

{

"A": 56.7, // Circuit 1 current value

"B": 55.8, // Circuit 2 current value（optional）

"C": 49.3, // Circuit 4 current value（optional）

"D": 1.2, // Circuit 4 current value（optional）

"deviceID": "860344048491162" // Device ID

}

5.2 Agreement Customization

If you need to customize other communication protocols, you can contact the business personnel to communicate them. This product orders over 1000 yuan, free custom communication protocol.

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 status/duration monitoring

8 Matters Needing Attention

(1) The product supporting transformer probe does not have waterproof function, such as outdoor use, need to be waterproof treatment.

(2) This product factory default built-in iot SIM card, the first year free, the next year from the traffic fee of about 20 yuan per year including free technical support costs. Please inform us in advance if you need to use your own SIM card.
