SN-WS wind sensor kit: anemometer and wind vane on a pole-clamped arm, IP65 node box with antenna and cable glands

Overview

The problem. Environmental quantities are critical in industrial sites but often go unmeasured: cold-room temperature, humidity in chemical stores, wind on crane and port yards (load sway, crane lock-out rules), panel and ambient temperature on solar farms, tank and well covers left open, motion outside working hours. There is no cable route for a wired sensor network; Wi-Fi/BLE sensors struggle with coverage and batteries; cloud IoT sensors require subscriptions and closed platforms. Alarms such as high wind or temperature drift do not reach anyone in time.

The solution. The sensor node family fits different sensor heads onto a single battery-powered LoRa node. The node sends periodic measurements (e.g. every 10 minutes) and an instant alarm packet when a threshold is crossed; the Wireless Gateway / RTU passes the data to SCADA or to the Telemetry & Process Intelligence layer via Modbus, MQTT or CSV, and WR-001 carries alarms to the staff member's pocket. The mains-powered version adds a local relay output: a crane lock relay when the wind limit is exceeded, a fan when a temperature threshold is crossed.

The family. The anemometer housing and PCB are designed by Elmes; the temperature-humidity node moves from the earlier SHT11-based design to modern SHT3x/SHT4x sensors; the level and door-contact nodes are derived from existing I/O firmware. Thermal, infrared and laser sensors are planned members of the family; they have no prototypes yet and are listed as coming soon.

Features

  • One node, interchangeable heads: temperature-humidity, anemometer, level and door/motion heads share one PCB family; the firmware profile recognizes the fitted head.
  • Local threshold relay (mains-powered): wind limit → crane lock; temperature → fan/heater; works without a central unit.
  • Elmes-designed anemometer housing: cup rotor, wind vane and body; 3D-printed prototype; gust and average values are computed on the node.
  • LED display option: a large temperature-humidity display (P10 LED panel) for warehouses and production areas.
  • TargetOptions: solar power, 868 MHz version, WR-001 pocket alarms, hydrostatic level, dual-technology PIR.
  • TargetEvent buffer and alarm-rate reporting: events are buffered on the node; reporting frequency increases during an alarm.
  • TargetSensor fusion: prediction and early warning from multiple nodes' data in the Telemetry & Process Intelligence layer, shared with Firesens. The AI-assisted false-alarm filter runs in this layer, not on the node.
  • TargetThermal, infrared and laser sensors: a thermal camera, infrared beam barrier and laser distance sensor are planned members of the family; there are no prototypes yet.

Frequently asked questions

Which sensors are available?

Today, at prototype and base-design level: temperature-humidity, anemometer (wind speed and direction), level float and door contact. Thermal camera, infrared beam barrier and laser distance sensors are planned members of the family; there are no prototypes yet.

How long does the battery last?

The target is 3 years or more at 10-minute reporting (temperature-humidity and door nodes). Because the anemometer counts continuously, a solar panel with a rechargeable battery is recommended. Measured results will be added to the specifications.

Can it stop a crane at the wind limit?

Yes, in the mains-powered version: the local relay signals the crane lock circuit when the wind threshold is exceeded, and the safe state on RF loss is configurable. It is an optional module for the Wireless Crane Control System.

Where can I see the data?

Through the Wireless Gateway / RTU via web, Modbus or MQTT; in your own SCADA or in the Telemetry & Process Intelligence cloud dashboard (planned). Alarms also go to the WR-001 pocket pager.

How do you prevent false alarms?

With hysteresis, consecutive samples, a gust filter and sensor fault detection. Multi-sensor fusion is planned; the AI-assisted filter runs in that layer, not on the node.

What is the range?

The battery node uses an internal or housing-mounted antenna; with the gateway's external antenna, kilometer-level range in open field is the target, to be confirmed by measurement. Repeaters are used inside warehouses.

Can it feed 4–20 mA to my existing PLC?

The node does not; the gateway provides the data over Modbus TCP. If a 4–20 mA output is required, the EC-AIO board from the I/O Carrier Boards family is used.

What about the warranty?

A 2-year warranty is planned; batteries and sensor heads are consumables.
