Schelt Technology

Sunshine Duration Sensor

Four identical omni-directional sensors under a hemispherical shading canopy.

Microcontroller contrast-evaluation to discriminate direct sunshine from diffuse sunlight.

Excellent performance even in difficult bright-cloud conditions.

Fully sealed, with a glass dome to protect the sensors.

Simple high/low output is used to indicate sunshine/no sunshine.

Operates at any latitude & longitude, and does not require alignment.

Marine-grade aluminium, hard anodised, for corrosion resistance.

Compact size and light weight.

WST-650 ultrasonic weather station is a compact and lightweight multi-sensor instrument that measures 6 essential weather parameters, which mainly including:

• Wind speed
• Wind direction
• Barometric Pressure
• Air Temperature
• Relative Humidity
• Solar radiation.

Features 

• Multi-parameter measurement
• WST-650 micro meteorological station uses ultrasonic technology to determine wind speed and direction.
• Relative Humidity is measured using an capacitive sensor.
• Piezo-resistive technology is used to measure the barometric pressure
• Air temperature by using diode junction voltage sensor.
• Photoelectric effect technology is used for solar radiation measurement. 
• High accuracy and free-maintenance
• WST-650 weather station has no moving parts, and it is resistant to contamination and corrosion.
• WST-650 weather station measures accurately and produces reliable data in demanding wind conditions and climates without periodic or on-demand maintenance.
• Configurable data output
• Digital signal output support ASCII and MODBUS communication protocol
• Analog signal output support voltage and current output optional.
