Description

The WIN-SN-LUX-M(200k) sensor utilizes a high-grade photodiode and advanced signal conditioning circuitry to deliver precise illuminance measurements across an exceptionally wide dynamic range. Its fully digital output eliminates analog signal noise and provides calibrated lux values directly via the Modbus protocol.

Engineered for industrial durability, the sensor operates reliably in temperatures from -10°C to 60°C and up to 80% relative humidity. The RS485 interface ensures noise-immune communication over extended cable runs, making it ideal for integration into distributed monitoring systems for smart buildings, greenhouses, and outdoor lighting control.

Key Features

  • Ultra-Wide Dynamic Range: Precisely measures illuminance from complete darkness (0 Lux) to intense direct sunlight (200,000 Lux).
  • Industrial-Grade Communication: Standard Modbus RTU over RS485 allows for easy daisy-chaining and integration with industry-standard PLCs and HMIs.
  • High-Accuracy Sensing: Delivers measurement accuracy of ±0.054 Lux, providing reliable data for critical lighting control and energy management.
  • Flexible Power Supply: Compatible with a wide 12-24V DC range and standard 230V AC, simplifying power sourcing in diverse installation environments.
  • Fully Configurable: Key operational parameters such as baud rate (1200-115200), slave ID, parity, and measurement thresholds are user-configurable via software commands.
  • Robust Environmental Protection: Designed with a compact, sealed housing for reliable performance in demanding industrial and outdoor settings.
  • Factory Calibrated: Each unit is pre-calibrated, ensuring out-of-the-box accuracy and eliminating the need for field calibration.
  • Low Power Consumption: Features an average current draw of 100mA with a low no-load current of 20-30mA, optimizing energy use in continuous monitoring applications.

Applications

  • Industrial and Commercial Lighting Control: Precise ambient light sensing for daylight harvesting systems in offices, warehouses, and factories to optimize energy efficiency.
  • Smart Agriculture & Greenhouse Management: Monitoring and controlling supplemental lighting based on natural sunlight levels to ensure optimal plant growth conditions.
  • Building Automation Systems (BAS): Integration into HVAC and BMS for intelligent facade and blind control based on external illuminance.
  • Outdoor Lighting Networks: Monitoring ambient light for automatic streetlight and public area lighting control at dawn and dusk.
  • Photovoltaic System Monitoring: Measuring incident solar irradiance as part of performance analytics for solar panel arrays.

Frequently Asked Questions

What is the communication protocol and how do I configure the sensor?

The sensor communicates via the industry-standard Modbus RTU protocol over an RS485 interface. You can configure key parameters like the baud rate (from 1200 to 115200 bps), slave ID, parity (none, even, odd), and measurement alarm thresholds by sending the appropriate Modbus function codes to the device using any standard Modbus master software or PLC.

What power supply options are supported by this lux sensor?

The sensor offers flexible power input options. It is designed to operate from a 12-24V DC supply, which is common in industrial control panels. Additionally, it can be powered directly from a 230V AC line, making it suitable for building automation installations without requiring an external DC power supply.

What is the measurement accuracy and operating environment for this sensor?

The sensor provides high precision with an accuracy of ±0.054 Lux across its entire 0-200,000 Lux range. It is built for reliable operation in industrial and outdoor environments, with an operating temperature range of -10°C to +60°C and humidity tolerance of 0-80% RH (non-condensing), ensuring stable performance in demanding conditions.
