Plant is affected by environmental factors. For example, these are temperature, humidity and light intensity. The light intensity affected strongly to the plant. The plant produces glucose and oxygen with photosynthesis. Moreover, light intensity is important to purify the contaminants in the atmosphere. In this study, it was examined whether the plant is affected by temperature, wind grade and soil moisture using bioelectric potential characteristics of the plant. Especially plant bioelectric potential to light intensity change was measured. The measurement was carried out in indoor and outdoor. As for the result, the differences of plant bioelectric potential characteristics in the indoor and outdoor were recognized. At that analysis, the integrated value of plant bioelectric potential for 1 minute (vm1) was adopted. Moreover, a high correlation was indicated between the vm1 and light intensity. The correlation coefficient was R2=0.94. It becomes obvious that the plant is affected strongly by light intensity and the plant can understand the environmental factors like light intensity. The characteristics are found by measuring bioelectric potential of the plant. The environmental sensing can be possible by the use of the plant bioelectric potential.
