Detecting motions or movements has always been important in most projects. With the help of the PIR Sensor it has become very easy to detect human/animal movements. In this project we will learn how ...

This project uses an Arduino board with a PIR motion sensor to detect movement. When motion is detected, an LED lights up and a buzzer sounds. It's ideal for simple security systems or motion-based ...

The circuit involves a PIR sensor as the motion detector, a relay to control the power to the bulb, and a transistor to drive the relay. The PIR motion sensor light wiring diagram is shown ... 10KΩ ...

Here is one simple circuit of a general-purpose white LED security light with Passive Infrared (PIR) Motion sensing mechanism. At the heart of the circuit is a PIR sensor module SB0061. SB0061 is a ...

2: Block diagram of motion sensor alarm The circuit diagram of the motion sensor alarm is shown in Fig. 3. It consists of a PIR motion sensor (MS1), Arduino Nano (Board1 ... the sample audio file and ...

The circuit diagram of the automation device using a motion sensor is shown in Fig. 2. It consists of an Arduino Nano board (MOD1), a PIR sensor (S1), a 230V AC to 9V secondary transformer (U1), a ...

To begin explaining how a basic sensor works, we'll use this rather nice diagram The PIR sensor itself has two ... These change pulses are what is detected. /* Chase * Motion Detection * PIR sensor ...

Let me introduce another simple microcontroller-based do-it-yourself circuit that detects motion ... and Arduino IDE compatibility. The code is an Arduino project for the Digispark Attiny85 to turn on ...

We can make an intruder alarm circuit at home which will be almost equally efficient for a specific range of distance and will be very low in cost. This article is about making an intruder alarm using ...
