“…Bluetooth technology measures signal strength for location and is a wireless transmission technology with short distances and low power consumption [37,38]. The positioning can be obtained by installing several suitable Bluetooth LAN access points in the room, configuring the network as a multiuser-based network connection, and ensuring that the Bluetooth LAN access point is always the master device of the piconet.…”

Due to the recent COVID-19 pandemic, many people have faced in-home isolation, as every suspected patient must stay at home. The behavior of such isolated people needs to be monitored to ensure that they are staying at home. Using a camera is a very practical method. However, smart bracelets are more convenient when personal privacy is a concern or when the blood oxygen value or heart rate must be monitored. In this study, a low-cost indoor positioning system that uses a Bluetooth beacon, a smart bracelet, and an embedded system is proposed. In addition to monitoring whether a person living alone is active in a specific environment and tracking the heart rate or blood oxygen value under particular conditions, this system can also send early warning signals to specific observation units or relatives through instant messaging software.

“…With the help of other suitable peripherals such as a camera, linear actuators and drivers, we can use ESP32 to implement a position control system [10] or a Smart surveillance system [11]. The ESP32 microcontroller is also used to perform Device-Free Passive (DfP) tasks such as detection, localization and the tracking of human entities [12], or utilized using GPS as an indoor positioning system [13] or security system [14]. SCADA systems have also begun to focus on IoT in recent years [15].…”

This chapter deals with the implementation of our own monitoring system with home security. The system is designed using IoT modules and uses ESP32 microcontrollers. The chapter describes the design of the system, its hardware components, software implementation, security solutions, communication, the collecting and monitoring of processed data, as well as the quantification of costs for the production and deployment of this system. The proposed system secures a house by detecting an intruder in the building, triggering an alarm and capturing it all with camera images, and then sending data to the owner’s smart mobile phone. The secondary task of the system is to collect data from sensors for monitoring the temperature of an object and presenting it via a web server.

“…An infrastructure-based indoor positioning system can be expensive, either because of the methods required or because of the expensive hardware components. Among all these technologies, BLE is one of the most widely used in ubiquitous computing and many Internet-of-Things (IoT) applications because it has many advantages such as low power consumption and low cost [ 7 , 11 ]. BLE transmitters or beacons are portable and easy to deploy, they have the potential to provide high positioning accuracy, and they can provide advanced services to users.…”

Indoor localization is becoming increasingly important but is not yet widespread because installing the necessary infrastructure is often time-consuming and labor-intensive, which drives up the price. This paper presents an automated indoor localization system that combines all the necessary components to realize low-cost Bluetooth localization with the least data acquisition and network configuration overhead. The proposed system incorporates a sophisticated visual-inertial localization algorithm for a fully automated collection of Bluetooth signal strength data. A suitable collection of measurements can be quickly and easily performed, clearly defining which part of the space is not yet well covered by measurements. The obtained measurements, which can also be collected via the crowdsourcing approach, are used within a constrained nonlinear optimization algorithm. The latter is implemented on a smartphone and allows the online determination of the beacons’ locations and the construction of path loss models, which are validated in real-time using the particle swarm localization algorithm. The proposed system represents an advanced innovation as the application user can quickly find out when there are enough data collected for the expected radiolocation accuracy. In this way, radiolocation becomes much less time-consuming and labor-intensive as the configuration time is reduced by more than half. The experiment results show that the proposed system achieves a good trade-off in terms of network setup complexity and localization accuracy. The developed system for automated data acquisition and online modeling on a smartphone has proved to be very useful, as it can significantly simplify and speed up the installation of the Bluetooth network, especially in wide-area facilities.
