iFarm: Development of Web-Based System of Cultivation and Cost Management for Agriculture

Applications of Smartphone-Based Sensors in Agriculture: A Systematic Review of Research

“…In many cases, it is still not clear from a full text review if any built-in sensors are used in the applications. However, we decided to include certain articles in which although the authors did not clearly specify the sensors used, we can infer from the functionalities of the applications such as retrieving location data via GPS as in [27,28,31]. We also excluded articles written in languages other than English and those of which we could not access full text.…”

“…The ability to keep records of farm workers' activities such as weeding, fertilizing, and harvesting in each area of the farm at specific time, schedule farm workers to different jobs, and communicate work plans to farmers is essential for effective farm management. Murakami et al and Murakami proposed iFarm, a system designed to assist in recording field data and communicating work plans, using smartphones, a cloud server, and web browsers [27,28]. Farmers in the field use an application on smartphones to record field data and send it to a cloud server.…”

“…As a large number of smartphone applications in Table 2 utilize cameras and GPS, we examine further into both hardware sensors. GPS are mostly used for location-aware applications, which send/receive essential environmental information for agriculture (such as pests and diseases [20,25,32], weather, soil [15], water [15], and radiation [26]), farm management information [27][28][29], locations of accident [30], locations of fields [23], and locations of farmers [29], based on users' locations. The aforementioned locationbased information seems to be able to tolerate some levels of location inaccuracy as environmental information or locations of farmers/fields/accidents can be reported in the vicinity of meters.…”

“…Then, we examine challenges of building smartphone applications to meet agricultural requirements. [27,28] 2013,2014 iFarm The application sends location-aware task lists to farmers on the field n/a Location of the user is sent to the central server, which sends only the relevant information about that location back to the user GPS Information systems [20] 2014 VillageTree Application user can report pest outbreak with the device location. The information is processed and a prediction is sent to users whose location might be invaded by the pest GPS Information systems [32] 2010 SMILEX Field worker's fire blight report from the field is coupled with the location data, so the incident report can be shown on the map for better fire blight management GPS , a directional view angle that has been shown in the agricultural research to allow the estimation of LAI to be free from leaf angle distribution and leaf degree clumping Accelerometer Farm management [29] 2013 n/a Accelerometer is used to detect various body movements in order to identify farm workers' activities Accelerometer Farm management [30] 2013 SafeDriving Accelerometer is used to obtain a roll angle and pitch angle of the tractor in order to detect a rollover event Gyroscope Farm management [30] 2013 SafeDriving Gyroscope is used to obtain a roll angle and pitch angle of the tractor in order to detect a rollover event…”

Sensor Fusion of a Mobile Device to Control and Acquire Videos or Images of Coffee Branches and for Georeferencing Trees

“…Mobile devices are used in agriculture mainly to control drones [ 4 ] or vehicles on land [ 5 ], to create ways to store information [ 6 ], or to connect to a network of wireless sensors, in order to manage, store, and upload each one of the measurements to the cloud in real time [ 7 ]. However, mobile devices work as tools for acquisition and processing of information, as well as, control and monitoring of the mentioned information.…”
