IoT Projects with Bluetooth Low Energy

By: Madhur Bhargava

Overview of this book

Bluetooth Low Energy, or Bluetooth Smart, is Wireless Personal Area networking aimed at smart devices and IoT applications. BLE has been increasingly adopted by application developers and IoT enthusiasts to establish connections between smart devices. This book initially covers all the required aspects of BLE, before you start working on IoT projects. In the initial stages of the book, you will learn about the basic aspects of Bluetooth Low Energy—such as discovering devices, services, and characteristics—that will be helpful for advanced-level projects. This book will guide you through building hands-on projects using BLE and IoT. These projects include tracking health data, using a mobile App, and making this data available for health practitioners; Indoor navigation; creating beacons using the Raspberry Pi; and warehouse weather Monitoring. This book also covers aspects of Bluetooth 5 (the latest release) and its effect on each of these projects. By the end of this book, you will have hands-on experience of using Bluetooth Low Energy to integrate with smart devices and IoT projects.

Preface

Temperature and Humidity Sensors


There are already temperature and humidity sensors commercially available in the market for both industrial and home solutions.

Note

You will find numerous climatic sensor solutions on the internet. For example, ONSET is one such company providing Temperature and Relative Humidity Data Loggers & Sensors. To know about it, visit http://www.onsetcomp.com/products/data-loggers-sensors/temperature-relative-humidity-rh.

One of the advantages about choosing a complete sensor solution rather than individual and standalone sensors is that sensor-based solutions are well packaged and come with extensive documentation and support. For example, the following is a TEMPERATURE-HUMIDITY SENSOR + EXTRAS known as DHT22:

This is a low cost and basic temperature and humidity sensor, which is great for learning about sensors and their internals. However, if you are looking forward to building a complete...
