GWM300 Wireless transmission module

GWM300 is an Internet of Things wireless data transmission terminal device. It provides three communication interfaces: RS485, RS232, and TTL. It supports point-to-point data transmission. Parameters can be configured through the USB communication port to facilitate communication with flow meters, temperature meters, pressure meters, and analytical instruments. Connect with various industrial field instruments and upload data to the cloud platform through the 4G network, thereby realizing remote monitoring on the computer or mobile phone (APP, WeChat applet, etc.). Widely used in electric power, petroleum, heat, communications, industry, meteorology, water conservancy, agriculture, transportation and other fields.

Application
Customer Case

Refrigerated container temperature monitoring solutions

Background

By monitoring the temperature in real time, refrigerated containers can ensure that the goods are within the appropriate temperature range during transportation, thereby preventing the goods from spoiling or deteriorating, avoiding harm to personal safety, ensuring that the transportation of goods complies with relevant regulations and standards, and at the same time improving transportation efficiency. Reduce transportation costs.

Pain Point

1. Wireless transmission, no distance limit

2. Real-time monitoring, high measurement accuracy

3. PC/APP remote monitoring, grasp the latest situation anytime and anywhere

4. Intelligent alarm (message/email/mini program)

5. Free cloud platform, intelligent data analysis and recording

Solutions

The entire temperature monitoring system consists of temperature sensors, secondary instruments, wireless transmission modules and monitoring cloud platforms. The temperature sensor measures the temperature of the refrigerated container and transmits the data to the secondary instrument for summary analysis. The data is packaged and uploaded to the cloud platform through the wireless transmission module for real-time monitoring. Not only can temperature abnormalities be discovered in time and corresponding adjustment measures can be taken, but it can also provide historical temperature data records and reports to help users conduct quality control and analysis of the transportation process.
