Information and Communication Technologies (ICTs) and the use of mobile devices have revolutionized practically all areas of human effort, giving users of these devices the ability to perform tasks that were possible through desktop computers. One of the areas that have helped from these technologies is agriculture, creating the term "Precision Agriculture (PA)". This article describes a low-cost infrared camera prototype to obtain the Normalized Difference Vegetation Index (NDVI). NDVI is used to estimate the quantity, quality, and growth of vegetation based on the measurement (via remote sensing) of radiation intensity in certain bands of the electromagnetic spectrum that vegetation reflects. This prototype is based on images taken to crops in controlled environments, two shots of the same objective are taken (one image in the standard color spectrum and a second image in the infrared spectrum, processing both images is how the NDVI index is obtained. A case study with applicability for agronomy is also presented where users without ICT experience can make use of these technologies in any kind of device (especially smartphones) to determine the health levels of plants in the same place without having waiting for processing or having to take the images to a specialized processing center.
