The initial iteration locates nodes at edge of each field and the latter distributes them randomly. Precision agriculture through WSN distinguishes external factors of monitoring to provide profundity on this field of study. Sensor networks require input from complementary components to complete monitoring and operational routines such as an irrigation system to control water level and humidity. [PERSON] and [PERSON] [21] proposed a \"low power wireless monitoring system\" for mosquito and pathogen related research. The system's purpose is to transmit information regarding humidity, temperature, wind speed and direction and location data for better control of mosquito populations and to prevent the spread related diseases. They've deployed a set of fixed, power autonomous and weather proof wireless climate monitoring devices based on a microcontroller that communicates to a Web based service through a low power Adaptive Network Technology (ANT) module. Moreover, the device security is enhanced through a radio-frequency identification unit (RFID) for secure control and manual user login of the module. The series of data is presented to a web browser application equipped with extensive graphical capabilities, and therein location related information is presented to a Google Maps based platform. Although our project embodies similar concepts, this work is specialized in population control and disease prevention. Additionally, sensors are geostationary and do not feature open source software and hardware properties. The three year design and deployment of WSN by [PERSON] et al. [22] aimed at seabird monitoring on Skomer Island (a UK National Reserve, located off the west coast of Pembrokshire, Wales). The research team developed a real-world deployable sensor network to investigate the habitat of Manx Shearwater (Puffinus puffinus) seabird. The project is based on battery powered sensor nodes communicating bi-directionally via Micro-Mesh-Protocol. The sealed devices were based on generic extension boards (MSB430 MS) and installed near the entrance of the bird's habitat (burrow) monitoring air temperature and humidity, movement on the entrance (passive infrared PIR), identity of individual bird (were marked previously with RFID tags) and weight of individual gird (with custom made scales). Recordings were initially saved in a SD card and selectively parsed to the repository through Micro-Mesh. Data and nodes were controlled by a custom built firmware with low level API based on ScatterWeb of Freie Universitat Berlin. Remote deployed and custom developed WSNs offer dependable recordings on specific implementations, but lack repeatability and broad applicability. [PERSON] et al. [23] proposed a \"test-bed for real-world Habitat Monitoring System (HMS)\" by acquiring remote physical environmental data. Their project can be implemented in any remote location using the Arduino Uno board, WI-FI connectivity and a Graphical User Interface (GUI). The nodes are consisted by a sensing, a power and a communication unit, which are monitoring temperature, humidity and light, while transmitting them towards a base station. The platform supports live data visualization on a hourly basis and the GUI manages the recorded data through a database built for this purpose. The project of [PERSON] et al. is an adaptable platform focused in easy deployment at specific remote areas. Our project is concentrated in the spatial aspect of monitoring, proffers portable operation and is compatible with modern mobile devices. [PERSON] et al. [24] dealt with the development of special nodes in order to monitor environmental parameters in aquaculture. Their method concerned the evaluation of monitoring an aquaculture system by deploying for the duration of six months two sensor network nodes in fish ponds. The overall framework consists three monitoring components: \"smart sensor nodes\", gateway/coordinator nodes--both based on the ZigBee platform--and a PC as monitoring center.
