IoT Gateway

IoT gateway is an electronic or embedded device that acts as a bridge between on-site devices/equipments like sensors/loggers/programmable controllers and server hosted on-site or in the cloud. The number of interfaces gateway supports typically determines the type and number of on-site devices it can be interfaced with and also its applications or end usage.

• supports interfaces like BLE, Wi-FI, Ethernet and Bluetooth. Additionally, interfaces like ZigBee or any particular interfaces can be provided if required. In general the gateway design is flexible enough to customize it to accommodate client requirements.
• can be connected with data Loggers, energy meters, and programmable logic controllers (PLC) over serial or Ethernet interface using communication protocols like Modbus, BACNet or proprietary protocols (if protocol document is available/provided)
• can communicate with Analog/Digital Sensor Hubs where individual sensors (temperature, pressure, flow) are aggregated and connected with Gateway over serial bus (SPI) or I2C.

Equally important is Gateway’s ability to compute and communicate with servers/platforms. Gateway offers enough space and computing power to implement analytics. It supports MQTT, HTTP (REST) and TCP-IP to communicate with, cloud platforms like AWS, Microsoft Azure and others.
