ANALYSIS OF LAND USE AND LAND COVER CHANGES OF WARRI METROPOLIS USING GIS AND REMOTE SENSING
ABSTRACT
This project is based on design and construction of a microcontroller process batch counter using limit switch. The project is basically on microcontroller controls circuitry. The microcontroller controls the operation, decision and functions of the device. The system consist of a conveyor belt an electric control unit and switching unit, the system conveyor carries the load or item from one end “A” to another end “B” of which the load passes through the limit switch position thereby closing the contact to enable the system count the object and register it on the seven segment display board. The device is used in batch and mass production manufacturing and branding of products.
