A PixelSensor configured for PAR measurements can monitor up to 8 wavelength bins (spectral bands) from 400 to 800nm


With accurate monitoring of natural light and LEDs, growers can adjust illumination from red and blue LEDs to boost power output and optimise plant growth cycles


Using these valuable insights, the operator can optimise the growing environment, allowing them to increase crop yields and enhance the nutritional value by adjusting different light characteristics. Furthermore, the Wave platform can identify opportunities for growers to reduce their energy bills and carbon footprint. Kachelek added: ‘We recommend a grower has


at least two WaveGo devices per facility. One can be used for automatically logging light levels in a particular area. The other can be used for spot measurements and creating overall performance maps.’ In a recent white paper, Ocean Insight explains how its Wave platform works when monitoring the LED output in greenhouse operations. A high-resolution spectrometer was used to measure the output of red and blue LEDs, sunlight, and the combination of the LED output and sunlight. Using these spectral


measurements, greenhouse operators can adjust their lighting schemes in real-time, optimising their efficiency. Wave provides an exceptional level of detail, operating with a 3nm optical resolution to help operators see the fine detail in the resulting spectrum. This helps operators compare the impact of different light sources, verify light consistency and analyse lighting in different areas. For some greenhouse environments, the


detailed measurements of a spectrometer may not be required. Instead, a sensor can be used to monitor sunlight and differentiate between various LED colours, providing a cost-effective solution.


The white paper also explains how this


system works, using a standalone multispectral sensor to continuously monitor PAR energy. The PAR PixelSensor comprises eight sensors, each of which monitors a different range of the optical


spectrum between 400 and 800 nm, and can be either integrated into a LED luminaire or placed close to the crops as a standalone sensor. Whatever real-time monitoring solution is


required, Wave provides operators with a wealth of intuitive reporting tools, allowing them to save key measurements and compare them with other data sources. Wave can also integrate with third- party cloud and lighting controllers, making it a highly customisable solution. Ocean Insight will continue to develop the


Wave platform, providing a rich set of light monitoring tools. Kachelek concluded: ‘We will continue to add new lighting calculations and features to the app. We will also push to integrate more directly with existing horticultural workflows and interface to other building management systems that growers may already be using to manage temperature, humidity, and other types of sensor devices.’ EO

Real-time monitoring of LED greenhouse lighting How optical sensing helps manage colour and power output


For growers and lighting providers, optical sensing tools that monitor light dynamically will be a key element of smart greenhouses. Sensors can be integrated into lighting fixtures, installed between crops and connected wirelessly for real-time control of greenhouse illumination and data management.
