Why Do Customers Need an Intelligent Water Quality Monitoring System?

Limitations of Traditional Water Quality Monitoring Methods

Traditional water quality monitoring usually requires technicians to collect physical water samples and perform laboratory analysis or manually check monitoring equipment. Although this method can provide reliable measurement results, it is not ideal for applications that require long-term and continuous monitoring. For example, environmental agencies may need to monitor multiple river sections, while aquaculture farms need continuous information about oxygen levels and water conditions. In these situations, manual monitoring cannot provide timely data.

Complete Solution Components & Hardcore Specifications

1. Water Quality Sensor – Accurate 8+ Multi-Parameter Measurement

The water quality sensor is the foundation of the monitoring system. It directly measures environmental conditions and provides accurate data for analysis and decision-making. To prevent field integration failure, BGT Hydromet supplies all sensors pre-engineered with external waterproof plugs and customized pin assignments processed directly at the factory before shipment.

Depending on project requirements, a single integrated BGT station supports the simultaneous multi-parameter monitoring of 8+ critical parameters. To ensure optimal power budgeting and signal purity, each individual telemetry edge node connects to exactly one sensor array.

2. LoRaWAN Node – Reliable Wireless Edge Telemetry (BGT-SN100 / SN200)

Unlike traditional wired data acquisition systems, the wireless node allows monitoring points to be deployed in locations where cable installation is impossible. Field configurations and logging frequencies can be customized effortlessly using a mobile device via near-field NFC configuration.

Advanced Smart Sampling Logic

The system supports instantaneous sampling, threshold alarm polling, and average sampling. To prevent data distortion from temporary fluctuations, the node can be configured to poll the sensor every 1 or 5 minutes (user adjustable), cache the readings internally, and upload the mathematical average value exactly every 30 minutes.

• Solar-Powered LoRaWAN Node (BGT-SN200): Merges a solar-harvesting panel with a high-capacity lithium backup pack, guaranteeing 30+ days of autonomous continuous operation during overcast or rainy conditions. Highly recommended for long-term outdoor arrays lacking stable grid connections.

• Battery-Powered LoRaWAN Node (BGT-SN100): Driven by ultra-low-power industrial lithium batteries, providing a continuous operational life of 3 full years without manual maintenance. Ideal for compact, low-power deployments.

• Flexible Installation Engineering: Supports wall-mounting or vertical pole-strapping with factory-included screws and heavy-duty hose clamps. For discreet or specialized environmental monitoring, the node is certified to be buried underground at a depth of 3 to 5 cm (Note: The node housing cannot be submerged directly underwater).

3. LoRaWAN Gateway – Long-Range Wireless Communication Bridge

The gateway intercepts edge RF packets and translates them into secure internet backhaul streams. Due to the high-frequency concurrent data processing required, gateways run continuously and must rely on main utility power grid connections (solar power setups require large-scale external battery arrays).
