Interfacing of 4G LTE with ATSAMD21 Microcontroller for Real Time Monitoring of Industrial Parameters

This study demonstrated that the production data from the weighing machine of the industry need to be monitored by the owner from anywhere in the world through wireless communication. Weighing machine in the industry is used for packing the items in a bag with proper measured quantity. These bags packed in a given time period must be calculated and the data must be sent to remote web server like Thing speak. In the industry, PLC ladder logic is used in the weighing machine for the control of the machine and the data from the machine i.e., the number of bags packed by the machine for a specific time period is recorded and the data is transmitted using 2G network now. Thus, this may delay the transmission of the recorded data to the cloud which reduces the efficiency of the data. This cannot be the assured data used for calculating the bags packed in the given time period. To overcome this problem, 4G network is used here for the faster transmission of the data. As 4G LTE has more advantages and additional features than 2G and 3G network such as faster than 3G, has extremely voice quality, easy to access the internet and better upload and download speed. Hence the ATSAMD21 Microcontroller is integrated with the 4G GSM module for the faster and wireless transmission of the data to the cloud. This improves the efficiency of the data transmission and thus helps the owner to monitor the production data from anywhere and the data is accurate.
