DAQ-IOT 4G/RS485/LoRa/WiFi/NB Wireless Irradiance Sensor

 

1 Product Overview

     
 

DAQ-GP-LR4G wireless irradiance sensor terminal is a wireless solar radiation measurement product launched by Shanghai Data Acquisition IOT Technology Co., LTD. The sensor uses the photoelectric principle and can be used to measure solar radiation in the spectral range of 0.3~3μm. The radiation sensor adopts high-precision sensor, wide spectrum absorption, high absorption in the full spectrum range, and good stability; At the same time, the induction element is installed outside the dustproof cover with a light transmittance of up to 95%. The dustproof cover adopts special treatment to reduce dust adsorption, effectively prevent the interference of environmental factors on the internal components, and can accurately measure the amount of solar radiation.

DAQ-GP-LR4G can directly read the current solar radiation value, and the connection mode is simple. Small and beautiful appearance, occupy a small installation space. The products are widely used in solar energy utilization, meteorology, agriculture, aging of building materials and air pollution and other departments to measure solar radiation energy.

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.

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:

{"light radiation":731,"ID":"860344048491162"}

Message analysis:

{

"light radiation": 731, //Light radiation, W/m^2

"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 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

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 Matters Needing Attention

This product factory default built-in iot SIM card, 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.
