Advanced LoRaWAN IoT Controller with Digital and Analog I/O – GAOTek

Description

Overview

GAOTek – Advanced LoRaWAN IoT Controller with Digital and Analog I/O is an IoT controller used for remote control and data acquisition from diverse devices. It contains multiple I/O interfaces including analog input, digital input, relay output, serial port, PT100 RTD input, which support remote device data transmission via LoRaWAN® or 3/4G networks. Besides, it supports multiple trigger conditions and actions which can work autonomously even when the network dropped. Combining with IoT Cloud solution, it can monitor and control remote devices via web server or mobile App easily.

Adopting industrial design and IP30 metal case, it is widely used in indoor applications like smart factory, building automation, etc.
