Global Solar Radiation Sensor (Pyranometer) for Weather Stations and Agriculture Monitoring
RS485 Solar Radiation Meter for Meteorological Observation, Environmental Monitoring, and IoT Weather Networks
Product Introduction (pdf)
Product Introduction
The KH.GDF Global Solar Radiation Sensor is a high-precision pyranometer designed for continuous measurement of total solar radiation in meteorological stations, smart agriculture systems, environmental monitoring networks, and solar energy applications.
The sensor uses a high-sensitivity photoelectric detection element to measure incoming solar radiation and convert radiation intensity into electrical signals. Advanced calibration algorithms ensure accurate and stable solar radiation data under different outdoor conditions.
With RS485 Modbus communication, the KH.GDF can be easily integrated into automatic weather stations, telemetry systems, SCADA platforms, and IoT-based environmental monitoring networks.
Its solid-state structure, compact design, and weather-resistant housing provide reliable long-term operation in outdoor environments with minimal maintenance requirements.
How It Works
The pyranometer measures global solar radiation received from the sun and sky across the sensor surface.
The detected solar energy is converted into electrical signals, processed internally, and transmitted as digital data for monitoring and analysis.
This measurement principle provides:
- Continuous solar radiation monitoring
- Stable outdoor measurement performance
- Reliable climate data acquisition
- Easy integration with weather monitoring systems
