How to make Motion Security System With Arduino - Robomart

The project with the motion-sensitive sensor -based security system will do our Arduino. In  many ways, the security detection algorithms. What will our security system with sensors with Arduino are sensitive to the movement of the project . The system detects motion alarm circuit will inform us of entering.

 Step 1: Required ​Materials: 

• Buzzer
• Arduino
• Led
• PIR Motion Sensor 

    

Step 2: Diagram of Electronic Circuit:

Step 3: Description

After uploading the software our alarm system is ready.

Note :  While passive 'HIGH' case, while active 'LOW' What happens in case when Project actively used for buzzer. You are the exact opposite to be passive buzzer, the software in the 'HIGH' and 'LOW' to change the situation.
