This document describes a temperature monitoring system using Arduino that displays temperature on an LCD screen and provides alerts via buzzer. The system aims to provide temperature monitoring at low cost without needing manual checks. It uses an LM35 temperature sensor, Arduino microcontroller, LCD for display, and buzzer to alert when temperatures exceed thresholds. While an IOT module was intended to send alerts over SMS or IP, hardware limitations prevented its real-time use. The system provides automatic monitoring and alerting of temperature changes.

Objective
» The project aim to give a display of monitor of room
temperature through LCD for data visualizing purpose.
» The project also aims to provide a automatic alert
through buzzing for temperature rise.This will help
alerting the person incharge for next cause of action
» The project aim to create a iot module which can sent
alert message for temperature rise and ip address for
temperature monitoring..

» a.Sensor Module
» A LM35 is used to detect the surrounding temperature
and sent the data to microcontroller for next action.
» b. Power Module
» The system can be power through adapter or USB.This
project used powers the Arduino project through usb.
» c. Controller Module
» The controller of this system isArduino Uno.The
Arduino board converts the Analog data which is
generated by the sensor to digital data. Arduino will
monitor the surrounding by getting the inputs from the
sensor.The microcontroller on the board is
programmed usingArduino programming language
and Arduino development environment.

» IOT module
» GSM IOT is used as iot board for this project.This gsm
will be sending messages from digital output to
wireless experience such as sms or wireless through ip.
Howeever due to the is hardware limitation, this
module was not be added on real time and simulator.
» e.Indication module
» Our indicatin module consist of LED lights which
indicate the normal and abnormal value.

» - Arduino is powered using the usb cable and the
sensor is connected to Arduino board and Led and
buzzer is connected for alert signal.The data from
sensor will be transfer to microcontroller and will be
processed.Then the then microcontroller will sent
signal to led and busser, if the temperaute is more than
27 , the led red will be light up and buzzer will buzz, if
the temperature is less then 25, the green led with light
up and indicate temperature is normal.
