Smart Agriculture: Gateway As Sensor Hub

IoT gateway in an agricultural greenhouse is the heart of a real-time control system composed of wired and wireless sensors, and electro-mechanical control systems to maintain an optimal growth environment.

Agriculture has benefited immensely by technology in recent times with dramatic increases in productivity.  Advances in agricultural mechanization in the few decades have removed the constraints of animal- and manpower limitation and ushered in the industrialization of agriculture. Today, agriculture technology is moving toward precision and intelligence, advancing hand-in-hand with the broader proliferation of IoT in all fields of human experience to continue to improve productivity.

The agricultural Internet of Things refers to the networked system composed of Internet of Things gateway connected to an array of sensors and sensor aggregators, as well as intelligent mechanical or electromechanical equipment throughout the greenhouse.  Important environmental variables such as temperature, moisture, pH, soil nutrient levels, light exposure, CO2 concentration are becoming important inputs to big data analytics designed to maximize productivity on an increasing granular scale.

Vantron’s rugged industrial gateways act as the nexus of information from all sensors, relay them reliably to the cloud management platform, and feeds back necessary control information to actuate environmental control complements such as irrigation, lighting, fans, or solar blinds.  Vantron’s gateways support a wide variety of protocols for downlink connection with sensors:  Zigbee, serial communications, Bluetooth, WiFi, and LoRa.  With edge compute capability and real-time 3G/4G or satellite uplinks to the cloud platform, a wide range of flexibility in local or centralized control algorithms can be implemented.     


Featured Product:


Vantron’s VT-M2M-G335 gateway is a robust, low-power, easily configurable, and highly cost-effective gateway specifically designed for Machine-to-Machine (M2M) communication for IoT applications.  Based on an industrial-grade TI ARM Cortex-A8 processor, this versatile gateway supports a wide variety of wireless protocols, including GPRS/3G/4G cellular, WiFi, Bluetooth, ZigBee, LoRa, and Iridium (9603) satellite communications.  Wired interface standard includes dual gigabit ethernet, RS232/485, USB, GPIO, and SD card slot, and can optionally support CAN 2.0b as well as other inputs.  With its array of short-range, long-range, and wired connectivity options to choose from, the VT-M2M-G335 is particularly well-suited as the sensor and connectivity hub for a smart agriculture environment.  Windows CE and Linux operating systems are supported, with SDK available.
