Temperature and Humidity Sensors With Arduino and Android

Future internet will not only comprise computers and computing things but also everything else. IoT is one of the emerging technologies. This chapter explores different kinds of temperature and humidity sensors, their specifications, usefulness, and prospective applications. Arduino boards are also explained in detail. This chapter explores the working principle and applications of different types of humidity sensors. The chapter contains the specification of common temperature and humidity sensors, pinout diagram, and schematic of the interconnection of sensors with Arduino Uno microcontroller. Working and interfacing of the ESP8266 wifi module are also explained. The chapter also provides the architecture and code examples of Android app for sensor data view and manipulation.
