HERNANDEZ PEREZ, Alberto  and  VINAS, David Elías. Electronic system design for recording the electrical response mimosa plant because of white light stimulus. Rev. Téc. Ing. Univ. Zulia [online]. 2015, vol.38, n.1, pp.58-63. ISSN 0254-0770.

We presented an electronic system for recording electrical response in a mimosa plant, due to white light stimuli is presented. For this, we designed and implemented electronic circuits responsible for converting the electrochemical activity of the mimosa plant into electrical energy, which is fitted with operational amplifiers and sent through an interface to a computer. The acquired information is stored in a text format file (*.txt) or Excel (*.xls, *.xlsx) and saved to a PC. In the case of the electronic record is put in charge of temperature sensors which monitor the same during the capture process and electrochemical electrodes that register electrical activity and signal converted in the environmental conditions to which the plant is subjected.
