【 摘 要 】

The objective of this work was to adapt a manual spray for herbicide application at specific site. For the development of the electronic circuit, a computer program in Assembly language was elaborated, with information on the variation of the electric resistance in LDR (Light Dependent Resistance), referring to the incident and reflected global radiation for four types of different surfaces (dicotyledonous plants, monocotyledonous plants, wheat straw and soil). It was concluded that it is possible and economically viable to utilize the LDR sensor to detect weeds.
