Sensor piranometer
The Veswe Pyranometer Sensor operates on the thermoelectric principle to accurately measure solar radiation within the 0.3–3 μm spectral range. It features an integrated desiccant drying cartridge that effectively prevents dew formation inside the domes, ensuring unobstructed performance in varying humidity.
A built-in bubble level with adjusting screws allows for quick, hassle-free leveling—eliminating the need for an extra base. Delivering high accuracy (supporting professional calibration) at an affordable price point, this pyranometer offers exceptional value for solar energy monitoring, meteorological stations, and research applications.

About - Pyranometer
The accuracy of this solar radiation sensor is very high and it supports inspection. This pyranometer can be widely used in solar energy utilization, weather station, agriculture, building material aging and air pollution and other departments to measure solar radiation energy. We also have a cheap solar radiation sensor for you to choose from.
Prinsip kerja
The pyranometer sensor working principle: The sensing element is a wire-wound electroplating thermopile, and the sensing surface is a black layer with high absorptivity. Utilize the thermal effect of radiation, absorb solar radiation to produce temperature difference, and output the measured value. It also has a temperature compensation function, which can accurately measure solar radiation.
The upper part of the sensing surface adopts a transparent double-layer glass cover with a light transmittance of 95%, which can not only reduce the influence of air convection on the equipment but also block the radiation of the cover itself. And add a radiation shield to measure scattered radiation.

Pyranometer installation
- Make sure to install the bracket, and the radiation sensor is parallel to the ground (leveling can be done through the leveling knob).
- Use screws to pass through the mounting holes on the sensor to fix the sensor on the mounting bracket.
- After installation, remove the protective cover.
- Please pay attention not to damage the glass cover during the installation process, so as not to affect the measurement accuracy.
- The installation location should be an open place all around and without any obstructions.
- After power on, preheat for half an hour before use.
Solar pyranometer sensor maintenance
- The glass cover should be kept smooth and clean, often wipe it with a soft cloth or fur.
- There must be no water in the glass cover. If it encounters heavy rain, snow, ice, and other long-term weather, it is recommended to cover it.
- It is recommended to check whether the desiccant in the dryer has become damp at regular intervals. The specific manifestation is that the orange turns into a dark color. If this happens, replace the desiccant in time, or remove the desiccant to dry and put it back into use.
- The equipment has been used for more than two years, and the sensitivity must be re-calibrated by the manufacturer or measurement department.
FAQs - Pyranometer
Pyranometer is a type of sensor that measures the solar irradiance or the power of sunlight in watts per square meter (W/m²). They are widely used in meteorology, climatology, solar energy studies, and agriculture to monitor and study the available solar radiation.

Output RS485:
Brown wire connected to positive power supply (10~30V DC), black wire connected to negative power supply, yellow wire connected to 485-A, blue wire connected to 485-B.
Analog output:
Brown wire connected to positive power supply (10~30VDC), black wire connected to negative power supply, green wire connected to positive signal, white wire connected to negative signal.
- When customers receive the pyranometer, please confirm the product model, etc.
- Do not connect the wires with power on. Only turn on the power after the wiring is checked and confirmed.
- The pyranometer sensor is a precision device. Do not remove the glass cover at will.
- If the reading value is 0, check whether the product protective cover is removed and whether there is sunlight.
- Please check whether the wiring is correct.
- Check whether the power supply meets the mark.
- The equipment is damaged.
- Thermoelectric solar radiation sensors measure full-spectrum solar radiation (about 300~2800nm), have a slow response time but high accuracy, and are often used in scientific research and standard measurements.
- Photoelectric solar radiation sensors mostly use silicon photocells, which are only sensitive to visible light and part of near-infrared, suitable for large-scale engineering monitoring but have a narrow measurement range.
- Photovoltaic power station efficiency monitoring
- Agricultural meteorological observation
- Building energy efficiency assessment (LEED certification)
- Scientific research and educational experiments
- Environmental monitoring station
