MQ-SG40W IP67 Solar LoRaWAN Smart Edge Gateway for Agriculture

MQ-SG40W

IP67 Solar LoRaWAN Smart Edge

Gateway for Agriculture

Overview

MQ-SG40W is an industrial-grade, IP67 weatherproof LoRaWAN smart edge gateway designed for smart agriculture, remote irrigation, and off-grid field automation. Unlike standard gateways that only forward data to the cloud, MQ-SG40W acts as a Field Edge Controller (MCU). It features a built-in LoRaWAN Network Server (ChirpStack) and local edge computing capabilities, enabling offline autonomy — meaning your irrigation schedules and valve-pump safety interlocks continue to run even when the internet goes down.

Equipped with a standard 60W solar panel and 30AH battery, MQ-SG40W is built for standalone operation in remote agricultural areas without grid power. It supports 4G, Wi-Fi, and Ethernet auto-failover, ensuring highly reliable data transmission.

Key Features

• IP67 Weatherproof & Solar Powered — Fully sealed outdoor enclosure paired with a standard 60W solar panel and 30AH battery. Engineered for continuous, off-grid operation in harsh field environments.
• Edge Computing & Local Autonomy — Runs local automation rules, valve-pump interlocks, and irrigation programs. Executes tasks locally and syncs with the cloud when reconnected.
• Built-in LoRaWAN Network Server (ChirpStack) — Standard ChirpStack v4 built-in. A single gateway is enough to build a local LoRaWAN network without external cloud dependency.
• Multi-Network Failover — Supports 4G LTE, Wi-Fi, and Ethernet with automatic switching (Priority: Ethernet > Wi-Fi > 4G) for maximum data link reliability.
• 8 LoRaWAN Channels — Supports 8 multi-channel RX and 1 TX, ensuring robust LoRaWAN communication.
• Global Frequency Bands — Configurable for EU433, CN470, EU868, US915, AU915, AS923, and IN865.
• Open for Secondary Development — Built-in Ubuntu OS with Node-RED, Node.js, and Python environments. Includes an isolated RS485 port for easy expansion.
• Multiple Integration Protocols — Supports UDP Packet Forwarder, ChirpStack MQTT Forwarder, AWS SNS, Azure, GCP, HTTP, and Blynk.

Technical Specifications

Edge Control & System Architecture

As an Edge Controller, MQ-SG40W sits between the cloud and field devices (sensors, valves, pump controllers). It manages data flow and executes critical logic locally.

• Local Safety Interlocks — Prevents water hammer, dry running, and overpressure at the edge level, regardless of cloud connectivity.
• Task Autonomy — Irrigation programs (Program/Station) and fertigation tasks are stored locally. If the cloud link is lost, the gateway continues to execute the schedule and reports back upon reconnection.
• Protocol Translation — Converts compact LoRaWAN hex payloads into JSON for the cloud (or Modbus-TCP for local SCADA systems), ensuring seamless integration.

Web Configuration & Management

• System Access — The gateway features an intuitive built-in Web UI. Connect via LAN, Wi-Fi AP, or remote 4G access. (Access credentials and initial setup instructions are provided in the hardware manual for security).
• Network Settings — Configure WAN, LAN subnet, Wi-Fi STA, and 4G APN settings directly through the interface.
• Gateway & RF Settings — Set the Gateway ID, Region Plan (frequency), and UDP/MQTT forwarding rules.
• ChirpStack Integration — Access the built-in NS to manage Device Profiles, Applications, and Nodes. View encrypted raw frames or decrypted payloads.
• Device Maintenance — System logs, firmware upgrades, time synchronization (RTC + NTP/NITZ), and system reboot.

Typical Applications

• Smart agriculture & precision farming
• Remote irrigation and valve control
• Orchard and vineyard field automation
• Soil moisture and weather station data acquisition
• Pump and fertigation control
• Off-grid solar-powered edge control networks

FAQ

Q1: What is the difference between this gateway and a standard LoRaWAN gateway?
A: A standard gateway only forwards data. MQ-SG40W is an Edge Controller. It executes irrigation programs locally and maintains safety interlocks even when the cloud is offline.

Q2: Does it require an external cloud server to operate?
A: No. It has a built-in ChirpStack LoRaWAN Network Server. You can deploy and manage a local network without cloud dependency. Cloud integration is optional.

Q3: What happens if the internet connection goes down?
A: The gateway switches to offline autonomy. It continues to run local schedules and safe interlocks. Once the network is restored, it syncs the data and status back to the cloud.

Q4: How is the outdoor gateway powered?
A: MQ-SG40W comes standard with a 60W solar panel and a 30AH battery system, allowing for off-grid operation.

Q5: Which global frequency bands are supported?
A: It supports EU433, CN470, EU868, US915, AU915, AS923, and IN865. You can select the region plan in the Web UI.

Q6: Can I do secondary development on this gateway?
A: Yes. It runs on Ubuntu with Node-RED, Node.js, and Python pre-installed. You can access the console via SSH or serial port for custom development.

Q7: How does the network failover work?
A: The gateway prioritizes Ethernet > Wi-Fi > 4G. It automatically switches to the active network link if the primary connection fails.
