This model is used to track and alert the user to take their valuables which was forgotten to take. The proposed system is show in Figure 1 of drawing section.

Background of the Invention:
The absent-minded people display forgetful behaviour in their daily life. They can have these different causes such as a low level of attention, Hyper focus. Hyper focus is a condition in which a person pays tremendous attention on a single item of focus. Absent-mindedness is a mental disorder. So, these absent-minded people have poor attention and is frequently distraction. Boredom, tiredness, or a concentration on internal thoughts rather than exterior surroundings are the factors which causes Absent-mindedness. People who are absent-minded often exhibit memory lapses and a lack of recall of recent events. This is commonly caused by a range of different disorders that physicians frequently diagnose, such as attention deficit hyperactivity disorder (ADHD) and depression. Aside from causing a slew of problems in daily life, absent-mindedness can also lead to more serious, long-term issues.
To overcome this problem, we developed a project called IOT based object tracking for absent minded peoples. Here we placed the small chip sized component into the thing, at which we want to track. Through our android application we can map the location of the object. The chip size component also has the alarm functionality, if we face any difficulty during map the location of our target object, with the help of alarm we can easily find our object by press find my object button. If user forgot to take the target object, at that time we notify the user to take that object by sending message. This project works with a GPS and Android application. A GPS monitoring unit, geotracking unit, or sincerely tracker is a navigation tool commonly on a vehicle, asset, character or animal that makes use of the Global Positioning System (GPS) to decide its motion and decide its WGS84 UTM geographic position (geotracking) to decide its location [2], The data given by GPS was sent to the NODE MCU (ESP 8266), it is IOT a component which was used to write data into firebase.
When user forgot to take the valuable at that time alert message will send to user mobile for notify the user to take the valuables. In-order to send the message, here we use the GSM module. Global System for Mobile communication is a full form of GSM. It was developed by European Telecommunications Standards Institute. With this GSM module we can send message to particular mobile user.
Node MCU is an open-source firmware for which open-source prototyping board designs are available. The name "NodeMCU" consists of "node" and "MCU" (microcontroller unit). Due to resource constraints, the user must select the module associated with the project Build the firmware that suits your needs. Support for 32-bit ESP32 was also provided. The commonly used prototyping hardware is a printed circuit board, which is Dual in-line package (DIP) that integrates a USB controller with a smaller surface mount Circuit board with MCU and antenna.
Firebase provide Database storage service to the developers. It is a NoSQL program which stores records in the form of JSON like documents [3]. Firebase is a service provided by google.

Firebase provide Backend-as-a-Service to the developers. With the help of Android application retrieve the data from firebase and map the location of the object with the help of google map API. Android Application is a software program designed to run on an Android tool or emulator. The time period additionally refers to an APK document which stands for Android package. This document is a Zip archive containing app code, resources, and meta information. Android apps may be written in Kotlin, Java, and C++ and are run inner Virtual Machine.
Drawbacks of Existing state-of-art and how the invention addresses the drawbacks:
The Apple has released air tag which was used to track the things like keychains, back bag, purse etc. It was launched on 2021 April 31. Its uses Bluetooth technology for tracking. Similar to our project they also track the things via IOS mobile app called Find My App. If user feel some difficulty in tracking, they can easily find their object by alarm sound which will generated by that air tag. The cost of this air tag is starting from Rs. 3190.User can use this tag by connected with their apple iPhone. The disadvantage of this air tag is, it was applicable only for IOS user. Android user can't use this air tag also cost is high when we compare to our project. Compare to apple air tag, this project additionally has the functionality which will alert the user at the time of forgot to take their valuable by sending alert message. This alert message will have the last updated location details in link form, when user click that link, they can track their object with the help of google maps. Also cost wise this project is minimal when we compare to air tag.
Objectives of the Invention:
Objective of this invention is to locate and track the valuables which was forgotten. Also alert the user via message if the user is out of the range (i.e. forgot to take their valuables).
Summary of the Invention:
The project IoT based Object Tracking and Alert System for Absent Minded People is main applicable for absent minded people. The object is located and tracked using GPS module. The object can be found in another way by triggering the buzzer so that the user can find the object by using sound. If the user forgets to take his valuables and leaves the place, an alert message is sent to the user along with the last updated location link.

ESP8266WIFI Module:
Figure 2 of drawing section shows ESP 8266 WIFI Module unit. It is a microcontroller that have comparable functionalities of Arduino. This ESP 8266 module have the inbuilt WIFI module, with the assist of this WIFI module we can communicate with firebase or other cloud service. It has the WIFI module, that is the advantage of this when we compare with Arduino. We can write the code in Arduino IDE software, through USB cable, here we fetch our code to this microcontroller. In bur project we use NodeMCU V3.
The NodeMCU (Node Microcontroller Unit) is an open-source software and hardware development environment built on the ESP8266, a low-cost System-on-Chip. The Espressif Systems ESP8266 has all of the necessary computer components, such as a CPU, RAM, networking (WIFI), and even a modern operating system and SDK. As a result, it's well-suited to a wide range of Internet of Things (IoT) projects.
On the other side, the ESP8266 is difficult to access and use as a chip. You must attach cables with the correct analogue voltage to the chip's pins for the most basic tasks, such as turning it on or sending a keystroke to the chip's "computer." You must also program it in low-level machine instructions that are understandable by the chip hardware. This level of integration is possible because the ESP8266 is used as an embedded controller chip in mass-produced electronics. Hobbyists, hackers, and students who want to utilize it in their own IoT projects will have a difficult time doing so.
The NodeMCU is available in a range of package styles. In all of the designs, the ESP8266 core is employed. In designs based on the architecture, the traditional 30-pin arrangement has been maintained. This is an important point to remember: some designs have a tiny (0.9") footprint, while others have a large (1.1") footprint.

The two most popular NodeMCU versions are the Arnica (which utilizes the traditional narrow pin spacing) and the LoL in (which has a wider pin spacing and a larger board). Because the ESP8266 is open-source, the market can generate new NodeMCU versions on a regular basis.
NEO 6M GPS Module:
Figure 3 of drawing section shows NEO-6M GPS Module unit. A GPS monitoring unit, geo-tracking unit, or sincerely tracker is a navigation tool commonly on a vehicle, asset, character or animal that makes use of the Global Positioning System (GPS) to decide its motion and decide its WGS84 UTM geographic position (geo-tracking) to decide its location. This GPS have one antenna and small controller. For power supply it has small size of battery. It has 4 pins that are TX, RX, VCC, GND. TX and RX pins are transmitter and receiver pins which is used to send the location details to NodeMCU. Through VCC we provide power supply and GND is connected to GND pin of the NodeMCU. GPS has the satellite navigation system. At initial it takes certain time to connect with satellite. If connection was success, the built-in LED which is available in GPS has start blinking so we will receive the location details along with present date and time. This GPS has the patch antenna which we will used to connect with satellite. A GPS receiver calculates its position by precisely timing the signals sent by GPS satellites. GPS is nowadays widely used and also has become an integral part of smart phones. It operates over 3.2 to 5V power supply. NMEA0183 is a output format of this GPS module.
SIM900A GSM Module:
Figure 4 of drawing section shows SIM 900A GSM Module unit. SIM900A Modem is built with Dual Band GSM based definitely SIM900A modem from SIMCOM. It works on frequencies 900MHz. SIM900A are trying to find those bands automatically. The frequency bands additionally may be set with the useful resource of the usage of AT Commands. The baud price is configurable from 1200-115200 through AT command. SIM900A is a very compact and wireless module. It is suitable for SMS, Voice further to DATA transfer software program in M2M interface. The onboard Regulated Power supply permits you to connect significant range unregulated power supply. Using this modem, you could make audio calls, SMS, Read SMS, attend the incoming calls and etc. through clean AT commands. This is a whole GSM module in a SMT type and made with a totally powerful single-chip, allowing you to benefit from small dimensions. SIM 900A GSM Modem with serial and TTL outputs.
The SIM900A GSM Module is the tiniest and most affordable GPRS/GSM module on the market. Arduino and microcontrollers are employed in the majority of embedded applications. The module communicates with a mobile sim card through GPRS/GSM technology. It uses the 900 and 1800 MHz

frequency bands to allow users to make and receive phone calls as well as send and receive SMS messages. Using the keypad and display interface, developers may design unique apps. Furthermore, it has two modes: command mode and data mode. In each country, GPRS/GSM and multiple protocols/frequencies are utilized. Developers can change the default settings in command mode to suit their needs.
Buzzer Module:
Figure 5 of drawing section shows Buzzer Module unit. An auditory signaling device, such as a beeper or buzzer, can be electromechanical, piezoelectric, or mechanical. The fundamental goal is to convert an audio signal into a sound signal. It's commonly found in DC-powered timers, alarm devices, printers, alarms, computers, and other electronic devices. Depending on the various designs, it may emit various sounds such as alert, melody, bell, and siren.
The pin layout for the buzzer is shown fig 3.4.1.4. There are two pins on it, one positive and the other negative. The positive terminal of this is denoted by the '+' symbol or a longer terminal. The GND terminal is connected to the positive terminal, which is represented by the '-'symbol or short terminal.
> Piezoelectric
> Electromagnetic
> Mechanical
> Electromechanical
> Magnetic
These are the some of the types of buzzers. When a voltage is put across a piezoelectric material, a pressure differential is formed, which is how a buzzer works. In a piezo type, crystals are placed between two conductors. Once these crystals have generated a potential disparity, they use their intrinsic characteristic to push one conductor and pull the other. A sharp sound signal will be created as a result of this continuous action.
Jumper Wires:
Figure 6 of drawing section shows Jumper wires. Jumper wires are basic cables with connector pins on both ends that may be used to link two locations without soldering. With breadboards and other prototype tools, jumper wires are widely utilized to allow for fast circuit adjustments as needed. It's a simple procedure. The most basic of all electrical components are jumper wires. The colors of jumper wires have no meaning, despite the fact that they come in a range of colors. A red jumper wire is the same as a black

jumper wire in this case. Colors, on the other hand, can be used to differentiate between other types of connections, such as ground and power. The most frequent jumper wires are male-to-male, male-to-female, and female-to-female. The terminating tip of the wire is what distinguishes them. Male ends have a protruding pin and can be inserted into objects, but female ends do not have a protruding pin and cannot be plugged into things. Male-to-male jumper wires are the most common and will most likely be required. Connecting two ports on a breadboard requires a male-to-male cable.
