The purpose of this project is to build a custom mobile device that has capability of reading several sensors$,$ parsing and

broadcasting required data over Wi$-$Fi$.$ The received data to PC should be treated in a target of drawing a temperature

map that uses the specific dynamic locations $($global latitude and longitude$)$ and corresponding ambient temperature.

Required equipment for electronic box:

$1.$ Arduino UNO

$2.$ ESP $8266-01$ Wi$-$Fi Module

$3.$ NEO$-6$M GPS Module

$4.$ NTC $($Negative Temperature Coefficient$)$ Thermistor

$5.9$ Volt Battery and its appropriate connector

$6.3\mathrm{.}3$ Voltage Regulator $($LD$1117$V$33)$

$7.$ On$/$Off Switch

$8.$ Appropriate headers and terminal blocks

$9.$ Appropriate resistors and capacitors

$10.$ Perforated Board

Required software for PC:

$1.$ Arduino IDE

$2.$ Appropriate program$($s$)$ to support Wi$-$Fi based communication and to be able to create Graphical Interface to

create temperature map. In this course, code pieces for C# and Python$3$ will be shared. It is allowed to use

multiple programs $($e$.$g$.$ one for receiving and parsing data, one for creating temperature map$).$

The connection diagram should be utilized roughly without pointing out the powering lines as in the Figure $1.$

Figure $1$: Rough connection diagram

The communication details are listed following:

$$ Arduino Uno and NEO$-6$M GPS Module $=>$ serial communication $($using software serial$)$

$$ Arduino Uno and ESP$8266-01=>$ serial communication $($using hardware serial$)$

$$ ESP$8266-01$ and PC $=>$ TCP $($Transmission Control Protocol$)$ via Wi$-$Fi

APPLICATION AND NOTICE

$$ NEO$-6$M GPS Module receives data from GPS satellites and sends data via hardware serial pins with the NMEA

standard protocol. This data should be parsed and interpreted in embedded Arduino UNO software

without using any third$-$party libraries.

$$ ESP$8266-01$ stands as a bouncer, where the data received from Arduino via hardware serial is being broadcasted

directly via Wi$-$Fi to PC with TCP$.$ On the other hand, the data received from PC via Wi$-$Fi is being sent to

Arduino UNO via hardware serial. Whole code to achieve this work will be shared, only some parameters

would be set by the students. It is important to note that the logic level of both hardware, Arduino Uno and

ESP$8266-01,$ is different to each other; the former uses $5$ Volts and the latter uses $3\mathrm{.}3$ Volts. Thus, this logic

shifting should be utilized in terms of hardware when the data is transmitted from Arduino UNO to

ESP$8266-01.$

$$ In order to start a communication between PC and the electronic box, both system should be connected to

common local network by using the same wireless modem. In order to reach the ESP$8266-01$ from PC

program, it is needed to know the local IP address of the ESP$8266-01,$ which can be reached from modem

interface.

$$ Students should create a PC program that receives data from ESP$8266-01$ via Wi$-$Fi with TCP and parse

all data $($ambient temperature and corresponding dual location information$)$ to use in the graphical

interface. With the same or separate program, an interface should be created where the dynamic

locations with electronic box should be scaled on the screen with the corresponding temperature that

creates temperature map
