Seven Sensor Plastic Wind Direction Sensor With Modbus Output 3S-WD-MB-P
The Wind Direction Sensor with Modbus Output is designed for accurate horizontal wind direction measurement in degrees (°) over a 0 to 359 range in compliance with IEC 61724-1:2021 Standards. The sensor body and wind vane work together to detect vane position and transmit wind direction digitally via RS-485 Modbus RTU. This makes integration straightforward with Modbus-enabled dataloggers, SCADA, and PLC systems. It is commonly used in PV monitoring to support module temperature interpretation and in reporting for wind-related warranty cases. The sensor is supplied with a mounting facility and cable.
Why Use a Plastic Modbus Wind Direction Sensor?
In larger installations, analog signals can degrade over distance or suffer from electrical noise. Modbus communication solves this problem by transmitting digital data reliably across long cable runs.
Choosing a plastic housing adds practical benefits outdoors, and it is usually a more economical option compared to metal-bodied alternatives, especially when you are deploying multiple sensors across a site.
The SEVEN Plastic Wind Direction Sensor with Modbus output is designed to deliver reliable wind direction measurement with easy installation and seamless integration.
- Reliable data over long distances: Modbus RTU over RS-485 keeps readings stable, even with long cable runs.
- Less electrical noise: Digital communication is less affected by interference from inverters, transformers, and other industrial equipment.
- Easy system integration: Works smoothly with SCADA, PLCs, and dataloggers that support Modbus RTU.
- Multiple sensors on one line: You can connect several devices to the same RS-485 bus by assigning different Modbus addresses.
- Corrosion resistance: Plastic housing is a strong choice for coastal regions and humid climates where metal parts may corrode over time.
- UV and weather durability: Quality outdoor plastics handle sun exposure well and help reduce long-term surface degradation.
- Lightweight and easier handling: Plastic construction makes installation simpler, especially on masts and rooftops.
- More economical at scale: A cost-effective choice when you need consistent wind direction data across multiple locations.

How Does the Plastic Modbus Wind Direction Sensor Work?
The sensor measures wind direction by tracking the position of the wind vane and transmitting the value digitally via Modbus RTU.
- Wind turns the vane so it points into the wind direction.
- A built-in Hall Effect sensor detects the vane’s angle without physical contact, which helps reduce wear and keeps readings stable over time.
- The sensor converts the measured angle into a wind direction value in degrees (0 to 359).
- This value is sent as digital data using Modbus RTU over RS-485, which is reliable for long cable runs and electrically noisy environments.
- The wind direction data is stored in Modbus registers, so your datalogger, PLC, inverter, or SCADA system can read it at regular intervals.
This working principle makes the sensor well suited for PV plants, weather stations, and remote monitoring sites, where long cable runs, low maintenance, and reliable data transmission are essential.
Where Is the 3S-WD-MB-P Commonly Used?
This Modbus wind direction sensor is widely deployed in:
- Utility-scale solar PV plants
- Hybrid solar-wind installations
- Meteorological stations
- Environmental and climate monitoring systems
- Agricultural PV and smart farming projects
In PV applications, wind direction data supports thermal loss analysis, soiling assessment, and structural risk evaluation, as required by IEC 61724-1.
