Abstract
This electronic document is a �live� template. The various components of your paper [title, text, heads, etc.] are already defined on the style sheet, as illustrated by the portions given in this document In recent years, automation of industries became necessary to monitor and control the various units in industries. Automation reduces manpower and helps efficient operation, which leads to reduction in cost and enhance profits. In the process of automation, a huge number of sensors are used to sense the various physical quantities such as temperature, pressure etc. Whenever a physical quantity exceeds the predefined threshold value then the micro controller or microprocessor will control the parameter by activating proper circuit [1]. A micro controller has only one or two parallel ports, which are not sufficient to connect huge number of sensors. Hence, a chip (AC16) is proposed. This AC16 chip facilitates 16 sensors connected to six micro controller pins thus allowing it to control more number of sensors. The chip (AC16) is addressed by four address pins. Each addressable chip is connected to sensor through ADC. Every chip receives address from micro controller and appropriate chip responds with data from sensor connected to that chip.
