Fingerprint Based Motor Control

Abstract

Irrigation water pump control is an important issue because unauthorized person also can switch ON/OFF (normal pump). Here we propose a solution to this problem by using a fingerprint authenticated starter system. The system provides a secure and hassle free way to start/stop motor. User just needs to scan finger to start pump, no need to carry any key. The system only allows authorized users to start the pump. Users can first register into the system by scanning fingerprints. The system allows multiple users to register as authorized users. When entering into monitoring mode, the system checks for users to scan. On scanning, the system checks if user is authorized user and starts pump for authorized users only. Here we use a microcontroller. The fingerprint sensor is connected to the microcontroller and also we have an LCD display along with push buttons and starter motor. The motor is used to demonstrate as pump starter. The system automates as well as irrigation water pump control using finger print based system.
