Aranet PAR Sensor
The Aranet PAR Sensor detects ‘photosynthetically active radiation’ a portion of solar radiation that falls between 400 and 700 nanometers and is used by organisms for photosynthesis. During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules. Optimum rates of photosynthesis produce maximum plant yields. There are 6 key factors that define the rate of photosynthesis and the growth of plants. They are Light Levels, Carbon Dioxide Supply, Temperature & Humidity plus Water & Mineral supply. They are all important and Aranet Horticultural Sensors help you monitor all of these variables.
