Build an alarm system to sound when someone walks by.Order Now
Continue the Electronics Course and make an Infrared Security System that can detect motion through body heat. You’ll learn all about PIR sensors, or passive infrared sensors and how you can use them as part of your Security System. First, assemble the hardware, making sure each part is in its correct position on the breadboard. Then, you’ll figure out how you can make the sensor more accurate by adjusting the sensitivity potentiometer. After, you’ll learn about implementing the modulo into your C++ program. Once your Infrared Security System is detecting intruders, figure out how to make it more complex with extra challenge exercises.
What you'll receive in the Infrared Security System project kit:
Push Button Cap
1/4W Resistors: 220Ω, 10KΩ
Jumper Wires M-M: 20cm (6, 2 extra)
Jumper Wires M-M: 10cm (4, 2 extra)
Jumper Wires M-F: 20cm (3, 2 extra)
You’ll unlock important new devices and learn how to make them work together in the Infrared Security System project kit.
Electronic Components. Learn about passive infrared sensors and how to connect them to the UNO R3.
Circuitry. Get the components ready to run by positioning them correctly on your breadboard.
Programming. Understand how to write a code that keeps track of whether or not the system is armed.
