Description
Overview
GAOTek reliable 4g cellular router for advanced connectivity is an OpenWrt based Linux OS industrial IoT gateway, which provides C/C++, Python programmable embedded environment for IoT developers and programmers to implement their industrial applications in a flexible and easy way. It has rich I/O like RJ45, RS232/RS485, DI/DO, USB, WIFI, GPS, and protocols such as MQTT, Modbus RTU/TCP, Modbus to Json, TCP/UDP, to collect and transfer the data from diverse sensors and controllers to the cloud, and remotely control the industrial equipment. Besides, its captive portal feature is ideal for WIFI advertisement applications of transportation. It has option of dual sim or dual module for failover or load balance, provides secure, robust and reliable wireless and wired connectivity for your mission-critical industrial applications, and it has been widely used for air compressor monitor and control, bus WIFI advertisement, water pump control, electricity substation monitor, etc.
