  • Abstract:
  • Precision agriculture has been widely discussed by the whole world in the last few years, and its advancement is highly dependent on nutrients within the soil. Among its main challenges is the proper detection of NPK content. This paper proposes the development of a colorimeter at the chip level for the purpose of NPK detection. It has a sandwich structure in which there is light source-microchannel photodetector for on-chip detection of analyte. In this the critical components are fabricated with MEMS technology. It is therefore very compact and much smaller than those of the conventional commercial colorimeters; it also shows high precision without much error. Its cost is also two orders lower than that of the conventional one. These advantages make it a promising solution for low-cost, high-precision monitoring in environmental and biological applications, having great potential use in precision agriculture.
