DESIGN A ALERT SYSTEM FOR A DEAF USING ARDUINO

Abstract

The project is an Alert System For A Deaf, where the sensor used to detect something or someone in front user house. The bulb will blinking when sensor detected something or someone in front user house And will stop blinking automatically when nothing have in front user house. This project made of Arduino UNO, Ultrasonic sensor, relay 5v, jumper wire, battery with connector, mini breadboard and 3pin plug with cable. This project useful for deaf to know when someone knock the door, to know if someone try to open the door or window to know if courier coming to delivery her order. This sensor can detect until 200cm length. This project focused to help a deaf to do daily routines without something bad happen. A deaf will more alert for any happen in their home or anywhere they go. The project is also having a positive impact for a long time.
