MONITORING THE COUNTING OF THE VISITORS

MONITORING THE COUNTING OF THE VISITORS

Here this project is used to design a project in which we can create a bidirectional visitor counter. The main intention behind this project is that whenever a person or the no. of persons is entering a room or leaving a room then it will be displayed on the screen. When a person enters the room, the count will be automatically increased and when they are leaving, the counting will automatically decreased. The IR sensing…

A MICROCONTROLLER BASED PROTECTION AND CONTROL OF A LOW VOLTAGE MOTORS BY USING ZIGBEE TECHNOLOGY

A MICROCONTROLLER BASED PROTECTION AND CONTROL OF A LOW VOLTAGE MOTORS BY USING ZIGBEE TECHNOLOGY

An induction machine plays a vital role in industry and there is s strong demand for their reliable and safe operation. They are generally reliable but eventually do wear out. Faults and failures of induction machines can lead to excessive downtimes and generate large losses in terms of maintenance and lost revenues, and this motivates the examination of condition monitoring. On condition monitoring involves taking measurements on a machine while it is operating in order…
