Abstract: The present invention relates to an apparatus, system and method for monitoring plant. A sensor means can be adapted for receiving plant growth information of the plant being received inside a container. An indicating means can be adapted for indicating information of the plant growth information. A wireless communication means can be adapted for transmitting the plant growth information to an external device. A control means can select a working mode of the indicating means and the wireless communication means. Through the cooperative effect of the sensor means, the storage means, the indicating means and the wireless communication means, operators do not have to take along with instruments to perform measurement reading of the on-site plant growth information at a regular time, thereby saving labor cost and time cost of monitoring the plant growth information and improving efficiency of plant monitoring.

Abstract: A method and apparatus for measuring water level in a container using RFID tag is provided. The water level tag group mounted inside the container is tested by a signal transmission and receiving device in order to determine whether there is a complete water level tag group in the testing area or not. Further, one complete water level tag group is chosen, and an inquiry process is made to all RFID tags of the selected complete water level tag group by the signal transmission and receiving device. An effective RFID tag will respond to the inquiry by sending out a radio frequency signal to the signal transmission and receiving device. The signal transmission and receiving device will then perform a data analysis and select a minimum water level value so as to obtain a real-time water level value of the container.
