Fig. 1: Author’s prototype Fig. 2: Block diagram of motion sensor alarm Circuit and working. The circuit diagram of the motion sensor alarm is shown in Fig. 3. It consists of a PIR motion sensor (MS1) ...

Motion detection is an essential part of security systems and PIR sensor is one of the most commonly used sensor for trigging the alarms when motion is detected. This sensor can detect human/animal ...

PIN Code Access: Secure the system with a 6-digit PIN. LCD Display: 16x2 LCD for user interaction and status updates (e.g., "Enter Pin", "Alarm Active", "Motion Detected"). Keypad Input: A 4x4 matrix ...

This home security device is a sophisticated system that integrates an Arduino Uno, PIR motion sensor, buzzer, and SIM900A GSM module. The device serves as an autonomous security solution for ...

Arduino Coding. After gathering all the components, open the Arduino IDE and write the following code (Fig 1). First of all, take a variable for motion sensor pin. Here we have used Arduino digital ...

arduino gsm security alarm. Working of the system is very simple and self-explanatory. When input power is applied to the system, the system goes into standby mode. However, when the terminals of ...

An infrared proximity sensor or IR Sensor is an electronic device that emits infrared light to detect objects and motion in Arduino projects. This active IR sensor module is perfect for obstacle ...

This project aims to help the public in protecting and avoiding criminal cases that are likely to occur in their neighbourhood. Such cases occur when the occupants are not at home or possibly even ...

This paper presents an innovative IoT-based smart home security system that integrates multiple sensors to detect various hazards and provide real-time alerts. Unlike traditional single-function ...
