An object locator is a device designed to assist its user in finding misplaced household and personal objects in a home. We probably spend hours every month looking for items around the home, often in a similar situation. In fact, almost every person in the world suffers this problem. But now this is not really a big problem because now there’s an inexpensive gadget to help people quickly find important items by tagging them and using an RF locator to pinpoint their position in seconds. Advantages of such locators include extensibility and low maintenance. In the past few decades, an unprecedented demand for wireless technologies has been taking place. Mobiles, Laptops, assistants (PDAs), and mobile phones, to name just a few examples, are becoming part of the everyday life of a growing number of devices that communicate wirelessly. RF radiofrequency are currently the main parts of the electromagnetic spectrum used to transmit information wirelessly. RF is becoming more popular every day and it is being preferred due to its inherent advantages like low power requirements, security, effective short distance communication as compared to its Radio counterpart. So we are using this technology in our project. In this project we aim to design and build a hardware model of RF receivers and simple RF remote can be used as the transmitters. It is very useful for blind persons to identify their objects using RF transmitter.      

Components Used:

• RF Transmitter, Receiver modules.
• 9V Battery.
• Buzzer.
