Coffee bean is one of the most cultivated products worldwide. Ecuadorian Andes have good conditions for the production of coffee, but many farmers have small plantations which difficult utilization of technology to improve crops productivity. Few studies focused on analyzing climatic variables that affect the optimum development of the coffee plant. We have developed a low cost a system to monitor environmental and soil parameters in coffee plantations in real time, in addition of keeping historical records of the measurements, is designed, developed and implemented to facilitate farmers management of crops. Also the system compare sensed values with optimum range for each of them and alert farmer if some action is need using a user-friendly interface.
