Industrial PAR Light Intensity Sensor MODBUS-RTU RS485
This MODBUS-RTU RS485 industrial-grade PAR (Photosynthetically Active Radiation) sensor measures real-time photosynthetically active radiation across the radiation range from 400 to 700 nm. It contains a Silicon photodetector and generates a voltage signal that is directly proportional to the PAR under the light source.
Features
- Compact size, simple installation, quick integration
- High performance: high accuracy, fast response, and superior stability
- Strong Robustness: IP66 Enclosure and it’s watertight and dustproof; can operate under a wide range of temperature: -30°C to 75°C
- Supports universal MODBUS RS485 protocol: connect to all MODBUS RS485 data loggers
- Wide-range Power Supply: ：5~24V DC
Sunlight has a tremendous impact on the lifecycle of almost all creatures on this planet. humans, animals, and plants all rely on the sun and its radiations. For plants, especially, light is a key factor in photosynthesis reaction and controls their survival. Different species of plants (for instance, C3 vs C4 plants) and even different growth stage of the same species demands different degrees of light duration, exposure, strength, and radiation range. Sun exposure, for instance, influences the foliage density, flowering, and fruiting of a plant. Sensors are thus a useful technology to help ensure the effective controlling of important parameters, like photosynthetically active radiation (PAR), contributing to the success of research or agricultural activities.
The industrial-grade PAR sensor featuring high performance, accuracy, and easy-installment, is designed to measure real-time photosynthetic light levels, which is the primary driver of plant photosynthesis. This instrument is able to monitor the PAR in environments with natural light sources across a radiation range from 400 to 700 nm and provides important parameters for researchers and farmers. The sensor contains a Silicon photodetector. When there’s light in, the sensor generates a voltage signal that is directly proportional to the PAR under the light source. You are able to obtain the measurement value in a unit of μmol/m2•s. The instrument supports the MODBUS-RTU RS485 protocol. You can therefore directly connect this PAR sensor with RS485 data loggers or digital voltmeters to create monitoring systems that meet your own demand.
This PAR sensor is robust with IP66 enclosure and is able to withstand a wide range of temperature from -30°C to 75°C, unlocking applications in harsh outdoor environments to support photosynthesis, solar, and ecological research, and to assist smart agriculture, outdoor large-scale plantation, greenhouse farming, tourism, meteorological sensing, etc.
