Security Alarm

Problem Statement :

Night duty security guards need a reliable and effective security alarm system to protect them from potential thefts while on duty. The lack of a proper security system puts the security guard at risk and compromises the safety of the premises they are guarding. The system should be designed to be tamper-proof and capable of working even in adverse weather conditions. Furthermore, the system should be easy to operate and should not require extensive training for the security guard. Without a proper security alarm system, the security guard is left vulnerable and at risk, which could result in the theft of valuable assets, property damage, or even physical harm to the security guard.

Hardware use :

Arduino Uno R3

Arduino is an open-source electronics platform based on easy-to-use hardware and software. It is designed for anyone interested in creating interactive projects, from beginners to experts. Arduino boards are programmable using a simple language that is similar to C++.

Arduino Nano

Arduino Nano is a small and compact microcontroller board based on the ATmega328P microcontroller. It is similar to the popular Arduino Uno board but is much smaller in size, making it ideal for projects with space constraints.The Arduino Nano board has 14 digital input/output pins, 8 analog inputs, and a 16MHz quartz crystal. It has a USB interface for programming and communication with a computer, and it can be powered either via USB or an external power supply.

RF module Receiver & Transistor

RF (Radio Frequency) modules are commonly used to wirelessly transmit and receive data or signals over a short distance. They are often used in remote control systems, wireless sensors, and other communication applications.

Relay module

A relay module is an electronic component that allows you to switch an electrical circuit on or off using a low-power signal. It is a type of switch that is controlled by an electromagnet, which opens or closes the circuit when it receives an electrical signal.

Explain Working Process

In this circuit, when the push button is pressed on the transmitter side, it sends a signal to the RF module which sends it wirelessly to the receiver side. The Arduino on the receiver side receives the signal and activates the transistor, which in turn activates the relay. The relay then switches on the load, allowing current to flow through it.

I have got a problem receiver and the transistor communication range is very Low.

I search on youtube how to range increase. that I found it … follow the video 👇👇
