A GNSS-enabled multi-sensor for agricultural applications

Abstract

Global Navigation Satellite System (GNSS) is becoming increasingly popular for its various advantages and potential for use in myriads of applications. Agriculture is one of the areas where GNSS is being used for enhanced efficiency, yield and better management towards cost effectiveness and environment-friendly approach. This paper describes the implementation of a geolocation enabled multi-sensor system for collection of climate and field conditions of any point of the agricultural field. The system consists of a Raspberry Pi to collect and/ or record data generated through a low-cost GNSS receiver and multiple sensors that can collect temperature, humidity and soil moisture along with precise coordinate of the field location. The system is cost-efficient, compact and consumes very low power from compact power sources ensuring autonomy and ease of operation. The system may be used for management of irrigation, pest control and yield analysis. Cost effectiveness enhances the scope for use of increased number of units over the field for overall efficiency enhancement.
