Design of wireless monitoring system in the chlorophyll content of rapes

Aimed to the remote monitor system of the chlorophyll content on crops, this paper brings forward a method that adopts the spectral analysis technology and Zigbee wireless communication module to realize measuring the chlorophyll content on rapes. It solves the problem that the traditional chemical analysis methods need long time to measure chlorophyll and difficult to non-destructive measurement, breaks the rule of detecting in the lab. This paper establishes the wireless measurement systems based on Zigbee, carries out the non-destructive measurement on the chlorophyll content of rape leaves, and has a guiding significance on precision fertilization.
