BGT-FWS1 RS485 Leaf Wetness Sensor

BGT-FWS1 leaf (Foliar) Wetness Sensor is an important tool for observing and studying leaf(Foliar) wetness, preventing pests and diseases, and spraying sprinkler control. The accurate measurement of the moisture content of the leaf(Foliar) surface can be used to monitor the trace moisture or ice crystal residue. The shape of the sensor is simulated by the blade, which can simulate the characteristics of the leaf(Foliar) surface, so that it can reflect the situation of the leaf(Foliar) surface more accurately. By measuring the variation of the dielectric constant of the upper surface of the blade, the mist, water vapor and ice can be measured.

Leaf wetness sensor

1. High-Precision Monitoring

Dual detection: Measures leaf wetness (0–100%) and temperature (-50°C to 80°C) with ultra-fine resolution (0.01% for moisture, 0.01°C for temperature). ±3% accuracy (0–50% wetness) and ±0.5°C temperature precision ensure reliable data for pest prevention and irrigation control.

2. Rugged & Weatherproof Design

IP67 waterproof rating withstands harsh outdoor conditions like rain, dust, and extreme temperatures (-40°C to 85°C).

Denser simulated leaf veins (15/cm) detect tiny droplets and ice crystals, mimicking real leaf surfaces.

3. Smart Connectivity & Customization

RS485/RS232/UART outputs with MODBUS-RTU protocol enable seamless integration into IoT systems.

Flexible parameter adjustments: Set baud rates (1200–38400), station addresses (1–255), and user-defined device IDs for multi-sensor networks.

4. Low Power & Fast Response

Peak current <30mA and rapid <1s response time for real-time monitoring.

Supports DC 5–24V power input with wide compatibility for agricultural setups.

5. User-Friendly Calibration

Simple 3-step calibration (0%, 50%, 100%) via pre-defined commands for accuracy maintenance.

Key Features:

Precision Agriculture Tool: 0.01% moisture resolution & ±0.5°C temperature accuracy.
Built to Last: IP67-rated, survives -40°C to 85°C.
Smart Farming Ready: MODBUS-RTU protocol for IoT integration.
Energy-Saving: 30μA standby, 10mA active.Customizable: Adjust baud rates, station IDs, and user tags.
Fast & Efficient: <1s response time, low power consumption.
