This should help serve as a concept for building a power efficient economic and environmental monitoring solution that can be scaled based on the expanse over which environmental data monitoring is desired. This paper present an approach to monitor the environmental data using commodity hardware like the Raspberry PI, sensor tag using BLE. The use of Bluetooth low energy (BLE) integrated in the Raspberry PI board along with the beacon technology for data transmissions helps serve the purse of a power and cost efficient solution. We could easily envisage various ways of processing this data to suite various business and enterprise needs. One such potential source of constant data feed are sensor devices which monitor wide variety of environmental data such as air pressure, temperate, humidity, orientation and further elements. With the advent of Internet of Things (IOT), multiple devices are getting connected with each of them being a big source of potential data. The constant growth of the digital enterprise has led a continuous growth of data sources and data that feeds into a potential big data eco system. Remote users can use it to interact with transducers by just using a regular smartphone or a tablet. As an example, an Android application based on the API is presented. Moreover, all HASITE functionalities can be accessed through an API, which also allows for the integration of third-party systems. According to the tests performed in different realistic scenarios, a transducer is ready to be used in less than 13 s. Thanks to the application of these three elements, HASITE is able to add new transducers by just powering them up. HASITE simplifies the deployment of a home automation system by using wireless networks and both self-configuration and self-registration protocols. These features are especially useful in situations where many transducers are deployed, since their setup becomes a cumbersome task that consumes a significant amount of time and human resources. This paper presents a novel home automation system named HASITE (Home Automation System based on Intelligent Transducer Enablers), which has been specifically designed to identify and configure transducers easily and quickly. The performed experiments show the feasibility of the proposed solution and its superiority, in terms of latency and energy consumption, with respect to approaches based on Generic Attribute Profile (GATT) when multiple users connect to a mote or in scenarios where latency is not a restriction, but where low-energy consumption is essential. ![]() ![]() Thus, the beacon specification is extended in order to increase its ability to manage unlimited sensors in a telemetry system without interfering in its normal operation with Eddystone frames. In order to demonstrate the capabilities of the designed protocols, the most restrictive (LP4S-6) is tested after implementing it for a telemetry application in a beacon based on Eddystone (Google's open beacon format). Thus, three protocols are defined depending on the beacon hardware characteristics: LP4S-6 (for resource-constraint beacons), LP4S-X (for more powerful beacons) and LP4S-J (for beacons able to run complex firmware). This article proposes a family of protocols named Lightweight Protocol for Sensors (LP4S) that provides fast responses and enables plug-and-play mechanisms that allow IoT telemetry systems to discover new nodes and to describe and auto-register the sensors and actuators connected to a beacon. ![]() Among the different commercial IoT devices, Bluetooth and Bluetooth Low Energy (BLE)-based beacons, which broadcast periodically certain data packets to notify their presence, have experienced a remarkable growth, specially due to their application in indoor positioning systems. Due to such constraints, IoT devices usually require lightweight protocols that optimize the use of resources and energy consumption. The Internet of Things (IoT) involves a wide variety of heterogeneous technologies and resource-constrained devices that interact with each other.
