This is a customizable alarm system built using Arduino Mega, designed to detect motion using ultrasonic and IR sensors, and trigger a buzzer alarm when intrusions are detected. The system can be ...

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 ...

The heart of this project is Arduino Uno which is the ... In the end, a LOW signal is sent to the LED, buzzer and the PIR motion sensor’s output pin. void setup() { Serial.begin(9600 ... So this was ...

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) ...

The output returns to, and stays at Low (L) when the motion has stopped. This output signal duration can be adjusted from near 0.3s to 18s by the onboard potentiometer. Another sensor suitable for our ...

The wire from digital pin 3 of Arduino gives sound output as a PWM signal of 10kHz frequency. This is to be filtered and amplified. Filtering takes place automatically in the amplifier. The alarm ...
