Description

The Renke RS-WS-N01-YM-1 leaf wetness sensor operates on the principle of dielectric constant measurement. Its sensing surface is engineered with a dense vein pattern to mimic a real leaf, enabling it to detect minute droplets and ice formation with high sensitivity. The integrated temperature sensor provides ambient condition data for comprehensive environmental analysis.

Housed in a black flame-retardant epoxy resin casing with an IP67 rating, the sensor is fully protected against dust ingress and temporary immersion, making it ideal for permanent installation in greenhouses, field research stations, and artificial climate chambers. Its RS485 interface supports multi-drop network configurations, allowing for scalable monitoring systems.

Key Features

  • Dual-parameter sensing: simultaneous leaf wetness and ambient temperature measurement.
  • Robust RS485 Modbus RTU communication protocol for industrial integration.
  • IP67-rated, epoxy-encapsulated construction for harsh outdoor and greenhouse environments.
  • High-sensitivity detection via a finely patterned leaf-vein simulation surface.
  • Wide supply voltage range (3-30V DC) accommodates various power sources.
  • Fast response time and excellent sensor-to-sensor interchangeability.
  • Designed for long-term stability and reliability in continuous monitoring applications.

Applications

  • Precision agriculture for monitoring leaf wetness duration to predict and prevent fungal disease outbreaks.
  • Greenhouse climate control and irrigation scheduling based on actual plant surface conditions.
  • Environmental research stations studying microclimate effects on plant health and dew formation.
  • Integration into smart farming and IoT platforms for automated crop management systems.
  • Laboratory studies in plant pathology and artificial climate simulation chambers.

Frequently Asked Questions

What is the communication protocol of this leaf wetness sensor?

The sensor uses the RS485 physical layer with the Modbus RTU protocol. This allows for reliable, long-distance communication (up to 1200 meters) and enables easy integration with PLCs, SCADA systems, and data loggers that support Modbus. You will need an RS485 to USB or RS485 to UART converter to interface with a computer or microcontroller.

Can this sensor be used outdoors year-round?

Yes, its IP67-rated epoxy resin encapsulation provides excellent protection against dust and temporary water immersion. The operating temperature range of -40°C to +60°C allows it to withstand harsh outdoor conditions, including freezing winters and hot summers, making it suitable for permanent field installation.

How do I power the RS-WS-N01-YM-1 sensor?

The sensor has a wide operating voltage range of 3 to 30V DC, offering flexibility in power supply selection. Typical applications use 12V or 24V DC supplies. Ensure your power source can provide the required current, as the sensor consumes approximately 0.75W. For multi-sensor networks, consider the total power budget of all devices on the RS485 bus.

What does the leaf wetness percentage output represent?

The 0-100% RH output represents the relative surface wetness, not ambient air humidity. A reading of 0% indicates a completely dry leaf surface, while 100% indicates a fully saturated or water-covered surface. The sensor's patterned surface mimics a real leaf, and the value correlates to the presence and extent of dew, rain, or irrigation water droplets.
