Photosynthetically Active Radiation(PAR) Sensor for Greenhouse/Farm Plant Growth RS485/Modbus

Photosynthetic Active Radiation Solar Light PAR Sensor:

Photosynthetic Active Radiation Sensor(PAR Sensor)  also known as the number of light quantum,is mainly used to measure the photosynthetic effective radiation of natural light in the wavelength range from 400 to 700 nm,and it is easy to use, which can be directly connected with digital voltmeters or data collectors and can be used under all-weather conditions.

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 photodetector in the sensor. Its sensitivity is proportional to the cosine of incident light direct angle. Each product is with one sensitivity coefficient respectively.It can directly output radiation value in unit of μ*mol/m2*s.

Photosynthetic Active Radiation Sensor(PAR Sensor)  is widely used in the study of agricultural meteorology and crop growth.

Photosynthetic Active Radiation Sensor(PAR Sensor)  Product Description:

This par sensor can be used alone for outdoor monitoring of radiation driving photosynthesis, or it can be used with a fixed weather station. Get accurate and cost-effective measurements of photosynthetically active radiation (PAR) from all light sources used to grow plants.

Photosynthetically active radiation sensors are designed to measure light intensity at frequencies associated with photosynthesis. This par sensor has a measurement range of 0 to 2000 W/m2 and a wavelength range of 400 to 700 nm. 

All aluminum shell material, good waterproof, can be used outdoor for long-term monitoring. Provide you with RS485/0-5V and other signal output methods.

 PAR Sensor Features

The PAR (photosynthetically active radiation) sensor adopts the principle of photoelectric induction. The par sensor working principle: when there is light, a voltage signal proportional to the intensity of the incident radiation is generated, and its sensitivity is proportional to the cosine of the direct angle of the incident light. 

This par sensor uses high-precision photoelectric sensing elements, with high absorption in the 400-700nm spectral range and good stability. The shell adopts special treatment to reduce dust adsorption and effectively prevent the external environment from damaging the internal components. 

Why Choose NiuBOL PAR Sensor?

High accuracy

The built-in sensor adopts high-precision photoelectric sensing element, which has high spectral responsivity and sensitive response to the spectrum of 400~700nm. A high-quality cosine corrector is used to ensure a standard cosine response, which greatly reduces the measurement error.

Long using life

The overall housing of the NiuBoL PAR sensor is made of a special aluminum alloy that will not accumulate dust and rain. This keeps the sensor clean and minimizes errors caused by dust blocking the radiation path. It can also work normally in harsh environments.

Remote monitoring

The par sensor can be connected to the customer’s own data device. Easily access data remotely, so you can view data through computer/APP anytime, anywhere. Accurate indoor/outdoor PAR measurement.
