(We also have to provide GND)  1-wire protocol is an advanced level protocol and each DS18B20 is equipped with a serial code of 64 bit which helps in controlling multiple sensors via single pin of microcontroller.  As DS18B20 follows 1-wire protocol so we can control this sensor via single pin of Microcontroller.  Data received from single wire is in the ranges of 9-bit to 12-bit. DS18B20 Introduction  DS18B20 is a digital temperature sensor which follows 1-wire protocol and can measure temperature from-55 o C to +125 o C (-67 o F to +257 o F) with an accuracy of +-5%. Finally, some schematics applications are exposed. We will also share some links of projects where we have interfaced it with Arduino or other microcontrollers. Pin-out description, working mode, protocol etc will be explained.

We will present a detailed overview of this temperature sensor in today's post. DS18B20 is generally used in industrial projects where high accuracy is necessary. Because of it's 1 wire protocol, we can control multiple sensors from single pin of Microcontroller. It follows 1 wire protocol which has revolutionized the digital world. DS18B20 is a temperature sensor which can measure temperature from-55 o C to +125 o C with an accuracy of +-5%. In this article we will introduce a one wire temperature sensor, well suited for WSN apps and IoT Applications. UART works by converting data into packets for sending or rebuilding data from packets received. We can only connect two UART devices together. In order to get good results we need also to connect GNDs Figure 1: Basic UART Connection Diagram One wire is for transmitting data (called the TX pin) and the other is for receiving data (called the RX pin). Figure 1 shows a basic UART connection diagram.

Here, we present connecting two UART devices together is simple and straightforward. It is a hardware device (or circuit) used for serial communication between two devices. UART stands for Universal Asynchronous Receiver/Transmitter. We will also write a simple sketch to explore serial interface for Arduino modules and present three applications with their code. 1) Introduction: In this work, we show what is UART communication and how it works. The protocol of communication is well explained and we finally, present three examples of using serial communication UART with Bluetooth, GPS sensor and for communication with another processor raspberry Pi. In this preprint we give an introduction on UARTs basically in Arduino modules. It allows user to communicate in serial mode or connect a device in wireless mode. UART is one of the most useful serial interface, it is presented in microcontrollers and in single board computers.
