Introduction
Cameran is a simple home security system built using Arduino UNO. Cameran uses an Ultrasonic Distance Sensor to detect how far away someone is from your doorway.
Idea
If someone is 100 feet away, the Arduino security system activates, and a green LED light comes on. If the trespasser comes closer than 75 feet, a warning is signaled in the form of a yellow LED light. This should discourage a trespasser from coming closer. If the trespasser comes closer than 25 feet at the door, a buzzer goes off and a red LED light comes on. A family member or an authorized person can enter a valid 4-digit passcode to silence the alarm. If the passcode is incorrect, the buzzer will continue to sound the alarm and a red LED light begins to flash to indicate that there is a potential intruder.
Prototype in action
For the sake of this prototype, I have designed the home security system using Arduino UNO that
- – activates with a green LED when movement is detected between 75 cm & 100 cm
- – shows a warning yellow LED when movement is detected between 25 cm and 75 cm and
- – lights up the red LED with the sounding buzzer when movement is sensed at less than 25 cm.
Watch the video to see the prototype in action.
Implementation details
Please check my project on the Hackster.io for information on components, schematics and the code.
Pro tip
When working on this project I came across an issue of shorting when I connected the 5V pin to the ground. If you see this issue as well, please check out my post on how to resolve it.
