Research output: Contribution to journalArticlepeer-review


The values of Normalized Difference Vegetation Index (NDVI) are directly related to the capacity of plant photosynthesis and important to crop growth. In this research, an attempt was performed to develop a real-time NDVI measurement device that eliminated the noise such as shadows and background soil. The developed NDVI sensor has the advantage of portability and the capability of real-time measurement of plant growth. The sensor has flexibility in operation, either manually or remotely. The system can be used with several interfaces to enable the communication using on-board Wi-Fi for image acquisition and NDVI measurement. Thus, the vision of this system is to develop an NDVI measurement sensor for using in field monitoring. The NDVT sensor could be manufactured commercially in a low-cost and would be convenient compare to other expensive similar commercial products.
