LED cube is a LED screen but with 3 Dimensions. It relies on optical phenomenon called Persistence of vision. It is used for decoration purpose and creating predefined animations.
Human Motion Detection Using PIR Sensor
This project detects the human motion using PIR (passive infrared) sensor module. This system can be used at any place where security is needed. The application areas of this project are Multi apartment complexes, shopping malls, basement parking area etc. Software used is Keil.
Automatic Room Light Controller
The project counts number of persons visiting a particular room and accordingly lights the room.
When someone enters or exits that room, the counter is incremented or decremented respectively.
When there is no one in the room, the light will be switched off.
This project is based on low cost and portable microcontroller heart rate counting system. The heart rate signals were collected from finger using LDR and light module which was amplified in order to convert them to an observable scale and displayed on LCD panel. This proposed project is applicable for clinic, sports healthcare and other medical purpose.
