gaia – Wireless Greenhouse Climate Control Board

gaia is a wireless greenhouse climate controal board and monitoring system engineered and designed for the farming industry.

gaia – Wireless Greenhouse Control Board

gaia may be regarded as the ideal greenhouse climate control and monitoring system for the farming industry. gaia can detect and analyse micro-climates: the data collected through in-house sensor is transmitted wirelessly in real time through ZigBee & Wifi to the control board in order to be processed. Compiled data is then accessible. This allows you to take decisions with regards to your needs. gaia also permits to pre-set automated actions that fit the requirements of your plants. Those pre-set parameters will automatically be applied when required.

Product Features

10. The user can set the desired environmental control conditions
11. Support multiple contexts, including the standard mode, heating mode, cooling mode and power-down mode
(a) Standard mode: can be set on and off conditions about the cooling fan, circulating fan, water wall, a canvas of water inside and outside the holding facilities, shading net, and insulation film equipment
(b) Heating mode: can be set on and off conditions about the greenhouse warming environment and all ancillary equipment
(c) Cooling mode: can be set on and off conditions about the cooling down environmental condition that flower blossom and all ancillary equipment
(d) Power-down mode: When a power outage can be set to start the generator and ancillary equipment in the environment on and off conditions
12. A full-screen graphic animation shows the current status of the greenhouse
13. Can store the data that are from the detectors in the greenhouse in the database system, and as access to historical data
14. You can use the dual-screen at the same time appear to control the current situation and historical data
15. The graph can be viewed on the PC to watch the information of all detectors
16. The Status of the electrical equipment usage can be recorded
17. You can use any remote control or remote viewing program (need to set the account and password) to watch and control the electrical equipment in the greenhouse
18. One key control (original electromechanical switch box control or automatic control)
