The solar radiation sensor, also known as a pyranometer or solar radiometer, is used to measure solar irradiance (W/m²) or accumulated energy (J/m² or Wh/m²) in real time.
Solar radiation sensor or pyranometer
The solar radiation sensor is not just a scientific instrument: it is a strategic ally for energy companies, smart agriculture, green urban planning and research centers.
The Plantae solar radiation sensor can be installed independently or integrated into the Plantae Meteo station.
The sun is the primary source of energy for plant life. Knowing how much solar radiation a crop or garden receives is not just technical information; it is:
- Key information to optimize growth.
- It helps to optimize costs.
- Improve sustainability by optimizing the use of water and fertilizers.

The solar radiation sensor measures the light incident on a surface in W/m² (instantaneous irradiance) and the energy accumulated over a period of time in J/m² or Wh/m², returning this data to the platform in real time.
Estos datos permiten tomar decisiones precisas en agricultura y jardinería, transformando espacios verdes en sistemas más productivos, saludables y eficientes.
By measuring in W/m² and J/m², it offers data that transforms sunlight into smart decisions, economic savings and environmental commitment.
The transition to a more sustainable world requires accurate data. One of the most important parameters is incident solar radiation, the amount of energy that reaches the Earth's surface and which determines both the efficiency of photovoltaic panels and the planning of energy, agricultural, and urban projects.
