HARVESTING – Smart greenhouse lighting management system

HarvestStation is an intelligent lighting management system. It not only controls the dimming of the luminaire, but also develops detailed lighting strategies. It supports lighting partition control, full cycle control, DLI sunlight data statistics, temperature and humidity data statistics. It can effectively balance sunlight and artificial lighting and save lighting power consumption as much as possible. Statistics can also help growers better improve their lighting strategies and increase productivity.

– Detect nominal sunlight value and statistically record sunlight DLI data.
– According to the set DLI requirements, the artificial light illumination is automatically adjusted according to the change in sunlight.
– An ensemble system can wirelessly control up to 40 lighting zones.
– A lighting zone can control up to 300 luminaires.
– The industrial-grade encrypted Zigbee wireless communication protocol is adopted in the system, and the recorded data can be stored in the cloud, which is safe and reliable.
– All controllers in the system can achieve IP66 protection level, easy to clean.


Host controller: The host controller is the central control unit of the system. It will collect the data always sent by the PAR and Temp/Humi detector, then control the dimming and archive the data statistics according to the requirements defined by the program. The host controller can connect to the Internet via network cable or WIFI signal and save the lighting strategy and statistics data configured by the user in the cloud.

PAR and Temp/Humi detector: The PAR Temp/Humi detector is the data collection unit of the system. it continuously collects sunlight PAR data to form DLI statistics. It also collects temperature and humidity data near the detector.

Users can view historical data statistics through the software. It can display statistics for the current day, current month, and current year.

Dimming controller: The dimming controller is the executive dimming unit of the system. It can output a 0-10V dimming signal to control the light output of the fixture connected to it. The dimming controller is controlled by the host controller, which communicates wirelessly with the host controller via Zigbee.

Dimming amplifier: The dimming amplifier is the dimming extension unit of the system. One end is connected to the dimming controller, the other end is connected to the next dimming amplifier, and the output end is connected to the light fixtures. The dimming amplifier can still output a 0-10V dimming signal to control the lights.


Sunlight in the greenhouse will cause some light loss after penetrating the top glass and trussing it. It is recommended to install the PAR Temp/Humi detector inside the greenhouse. Below the glass, above the sun visor. It can be located slightly higher than the truss. Once the PAR Temp/Humi detector is operating normally, it collects the insolation data after entering the glass and forms a statistical record that the grower can query. In DLI control mode, the host controller can control light dimming based on changes in sunlight collected by the PAR Temp/Humi sensor.

In DLI control mode, user can control the lights running time. During the user-defined photoperiod, the fixture will provide supplemental illumination when sunlight is low and the fixture will turn off when sunlight is increasing. The system will comprehensively calculate the DLI data provided by sunlight and artificial light, and dynamically change the brightness of the light.


In DLI control mode, when the system detects the sunshine data is too low, it will judge that it is currently cloudy and the lights will turn on to provide additional illumination.
