Description

The WIN-SN-LUX-M sensor utilizes a high-quality photodiode and advanced signal conditioning circuitry to deliver accurate and stable luminous intensity readings. Its digital output via Modbus RTU ensures noise-immune data transmission over long distances, making it suitable for distributed monitoring networks.

Engineered for reliability, the sensor features a rugged enclosure capable of withstanding industrial conditions. The integrated relay provides a direct control output that can be programmed to trigger based on user-defined LUX thresholds, enabling automated lighting and shading systems without requiring an external controller.

Key Features

  • High-resolution light sensing with a broad dynamic range up to 65,5k LUX.
  • Industrial-standard RS485 interface with configurable Modbus slave ID and baud rates (9600-115200 bps).
  • Integrated Form C relay output (SPDT) for direct control of lighting loads or alarms.
  • Dual power input options: standard 12-24V DC and optional 230V AC for versatile installation.
  • Designed for long-term stability in environments from -20°C to +60°C and 0-70% relative humidity.
  • Compact and low-power design with an average current consumption of approximately 100mA.
  • Includes a shielded twisted-pair cable (22 AWG) for reliable signal integrity.
  • Simple mounting and configuration via accessible Modbus registers.

Applications

  • Industrial lighting automation and daylight harvesting systems.
  • Smart building management for HVAC and lighting control based on ambient light.
  • Greenhouse and agricultural environment monitoring for optimal plant growth.
  • Outdoor lighting control in streetlights, parking lots, and tunnels.
  • Data logging and environmental monitoring in distributed IoT networks.

Frequently Asked Questions

What is the communication protocol and interface of the WIN-SN-LUX-M sensor?

The sensor communicates using the industrial Modbus RTU protocol over a standard RS485 interface. This allows for reliable, noise-immune data transmission over distances up to 1200 meters. The slave ID, baud rate (from 9600 to 115200 bps), and measurement parameters are all configurable via Modbus registers.

How do I power the sensor and what are the electrical specifications?

The primary power input is 12-24V DC. An optional 230V AC power version may be available. Under typical operation, the sensor draws an average current of about 100mA. Ensure your power supply can deliver sufficient current and is properly grounded to minimize electrical noise on the RS485 line.

Can this sensor directly control lights or other equipment?

Yes, the module includes a built-in Form C (SPDT) relay. You can configure specific LUX threshold values via Modbus. When the measured light intensity crosses this threshold, the relay changes state, providing a direct dry-contact output to switch lighting loads, alarms, or other AC/DC devices without an external PLC.
