Project Name : Ultrasound Fog Lamp
Theme Name : Disaster Management
Disaster Management Present day fog lamps work on optical light which cannot penetrate through dense fog. Infra-red fog lamps are also being used, but they are expensive. We realized that ultra sound being a longitudinal wave can pass through fog deviated and hence can aid in guiding a vehicle through fog. So we constructed a fog lamp like device, based on the principle –
“Working of SONAR”.
We placed on ultrasound transmitter receiver pair in front of the vehicle and converted the ultrasound received after reflection into electricity. This electricity is used to activate a light bulb or a buzzer so that the driver is alerted of the presence of an object in front of him/her.
The ultrasound fog lamp is an innovative solution which is efficient and cost effective. This can save lives.
