Abstract:
In
order to accurately determine the growth of greenhouse crops, the system based
on AVR Single Chip microcontroller and wireless sensor networks is developed,
it transfers data through the wireless transceiver devices without setting up
electric wiring, and the system structure is simple. The monitoring and
management center can control the temperature and humidity of the greenhouse,
measure the carbon dioxide content, and collect the information about intensity
of illumination, and so on. In addition, the system adopts multilevel energy
memory. It combines energy management with energy transfer, which makes the
energy collected by solar energy batteries be used reasonably. Therefore, the
self-managing energy supply system is established. The system has advantages of
low power consumption, low cost, good robustness, extended flexible. An
effective tool is provided for monitoring and analysis decision-making of the
greenhouse environment.
