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), ...

We have also built a simple Rain Alarm and an automatic car wiper by using 555 Timer only, you might want to check that as well if you do not want to use an Arduino. That being said, let’s get back to ...

Step 3: Working Of The Circuit The working of this circuit is very simple. At first, the state of the PIR sensor is set to LOW. it means that no motion is detected. When a motion will be detected by ...

Insert the Arduino Nano and MQ-2 smoke sensor in the breadboard. Power up the sensor through Arduino and connect the A0 pin of the sensor to A5 of Arduino. Connect a buzzer and an LED in a parallel ...

Today we are adding one more Security Alarm in our list which is based on Ultrasonic Sensor. This Arduino Controlled Door alarm can be installed near the door to detect the presence of anybody at the ...
