Description
CDG-12B Quantum PAR Sensor
The CDG-12B PAR photosynthetically active radiation sensor for measuring solar radiation within the 400 – 700nm wavelength. It is easy installation and can work continuously in all weathers. When there is sunlight, voltage output proportional to incident light intensity will be generated by the silicon- photo detector in the sensor.
Its sensitivity is proportional to the cosine of incident light direct angle. Each product is with one sensitivity coefficient respectively. PAR sensor can directly output radiation value in unit of μ*mol/m2*s.

Application
Agricultural field:
◉Help farmers and growers accurately understand the intensity and distribution of light in the field or greenhouse, so as to rationally arrange the planting location of crops, conduct shade management, and determine whether supplementary light is needed to ensure that plants get the best light conditions, improve photosynthesis efficiency, increase crop yield and improve quality.
◉Farmers, horticulturists, or relevant operators can use it to monitor the natural light or artificial light environment in real time. This enables them to adjust light time, intensity, spectrum, and other parameters. By doing so, they can meet the light needs of different crops in various growth stages, especially in greenhouse planting, plant factories, and other controlled – environment agriculture scenarios. Their use of this method is widespread, helping to achieve precision agriculture and efficient production.
Ecological study:
◉To measure the distribution and variation of photosynthetically active radiation in natural ecosystems, to understand the photosynthetic capacity of plant communities, to evaluate the primary productivity of ecosystems, to study the structure and function of ecosystems, and to study the interrelationships between ecological processes and environmental factors.
◉Scientists/Researchers monitored the light – use efficiency of different vegetation types under different environmental conditions and analyzed the coupling relationship between vegetation growth and environmental factors such as light, temperature, and water. This provides a scientific basis for ecological environment protection, vegetation restoration, and ecosystem management.
Environmental monitoring:
◉PAR is an important part of the Earth’s energy balance, and changes in it affect photosynthesis in plants and the carbon cycle in ecosystems. Long-term monitoring of temporal and spatial changes in PAR, combined with other meteorological data, helps to study the impact of climate change on ecosystems and the mechanisms by which ecosystems respond to climate change.
