What the Auto Control System Includes:

The system is built from four parts: a weather station, sensors, a master control and a microcomputer. The weather station and the sensors are the eyes of the set up, reading the environmental factors that matter to the crop, temperature and light intensity among them.
 

How the Control Loop Works:

Those readings are fed back to the computer, which compares them with the parameters the grower has set. When a reading drifts away from the set value, the computer drives the facilities in the house to bring it back: window opening, film roll-up, cooling and heating. In other words the house is not run by guesswork, it is run by what the sensors report, and the environmental factors are held at the values that suit the crop.
 

What It Means for the Crop:

The point of the control loop is a growing environment that stays where the crop needs it. Ventilation is opened when the house warms up and closed again when the temperature falls, film is rolled up for the day and back down at night, and heating picks up the load in cold weather, all of it against the same set of parameters rather than against a person walking the house from end to end. Because the values are held steady through the day and night, the crop meets fewer swings, and the work that used to be manual venting becomes supervision.
 

Equipment and Support:

The control system is supplied as part of the equipment range, together with the greenhouse accessories range it is mounted with, ventilation equipment and irrigation and fertilizing systems, so the whole house is specified as one set instead of being assembled piece by piece. You can read more our greenhouse factory, or ask us which configuration suits your house: call +86 191 5068 3942 or send an E-mail to sales@cngreenhouses.com.
 
Reference material on controlled environment growing is published by organisations such as the FAO, and commercial greenhouse practice is reported by trade media such as HortWeek.
 

Frequently Asked Questions:

Q: Do you also provide greenhouse accessories and systems?
A: We produce tunnel greenhouses, single-span film greenhouses, multi-span greenhouses, PC sheet greenhouses, glass greenhouses and sawtooth greenhouses. We also supply the complete supporting systems: cooling and heating, irrigation, fertilization, hydroponics, ventilation, lighting and automatic control.
Q: Do you have experience with projects similar to mine?
A: We export to more than 32 countries, including Russia, the UAE, Kuwait, Nicaragua, Canada, Chile, South Africa and Uzbekistan. We ship worldwide.
Q: How do I pay for a greenhouse order?
A: We accept T/T and L/C. The specific terms are confirmed in the contract before production starts.
Q: What does the automatic control system consist of?
A: Four parts: a weather station, sensors, a master control and a microcomputer. The weather station and sensors read environmental factors such as temperature and light intensity, and they report back to the computer.
Q: What can the system control in the house?
A: Window opening, film roll-up, cooling and heating. The computer compares the sensor readings with the parameters you set and drives those facilities to bring the reading back to the set value.
Q: Do I still have to watch the greenhouse myself?
A: The system reacts to the sensor readings rather than to someone walking the house, so the set values are held through the day and night. In practice the manual venting work becomes supervision, and your attention goes to the crop instead of the vents.
