Zigbee Based College Bus Data Monitoring System

The college-bus database monitoring and controlling system in the college need to be continuously monitored by the computer. These monitoring system include bus transition monitoring system, where continuous monitoring and parameter checking required.

Most of the current monitoring and controlling system having human interfaces and some difficult task like maintaining such data with accuracy. It is impossible for the college bus-worker and management staff to continuously work only for such task. So to solve this problem, we can provide wireless network link like ZigBee.

The characteristics of ZigBee like low power, low cost, range up to 100 meter and network forming ability make ZigBee technology an ideal choice for wireless monitoring and controlling network in this system.

In our proposed College-Bus Data Monitoring system we are using ZigBee module, p89c51rd2 microcontroller system and one pc interfaced with it, who monitor continuously. This module  send the unique code for each bus at the time of entering or exiting college campus to the ZigBee enabled p89c51rd2 microcontroller system interfaced with computer.

In computer by using data logger software we are storing that updated data in database with time & date. so like this we will have all bus transition data automatically with accuracy without maintaining any hand written database.

Bomb Detection Robot Project

The design scheme of this robot is based on the recognition metal based on the principle of mutual inductance. This is verified by on-board reference comparison. The metal detection circuit is mounted on a robot which is controlled by RF.

This Bomb Detection Robot project is developed on embedded platform, whose software platform use the firmware written in embedded C. The metal detection circuit contains a coil which when placed over a metal, changes the response of the system and inturn the system signals the remote node about the detection and rings a buzzer on the robot.

The whole Bomb Detection Robot project is implemented on 8051 based AT89S52 controller and the compiler used is RIDE/KEIL. the remote metal detecton values are displayed on the LCD. The controlling of the robot is enabled with zigbee network.

Hotel Power Management System Using LDR

Abstract

This is a unique Hotel Power Management System Using LDR project designed to save electrical bills especially in hotel environment.

It normally happens that costumers come to the hotel and while going out from the hotel they often leave the lights and fan ON. Normally the consumers surrender the key to the reception staff while leaving. If the reception staff failed to check the room more amount of power will be wasted.

This Hotel Power Management System project is designed to monitor the movement of the persons in the room with LDR sensor, this sensor will send signal to the controller and the controller checks the light intensity if the light intensity is less in the room, the controller will respond and will turn on the power.

8051 Microcontroller,
KEIL Compiler,
LCD,

Accurate Electricity Monitoring of the Household Appliances

Aim: The main aim of this project is “To reduce the interference and to get the accurate electricity monitoring of the household appliances”.

EXISTING SYSTEM: In the existing method electricity can be monitored by using the parameters like voltage and current these 2 Parameters can be sensed by using the voltage and current sensors. but the controlling of the devices in the house is not possible in the existing system. to overcome this disadvantages we are going for proposed method.

PROPOSED SYSTEM: The A Power Sensor Tag with Interference Reduction for Electricity Monitoring Of Two-Wire Household Appliances project consists of voltage sensor and current sensor and loads. The house hold appliances like bulbs consume power.

The parameters current and voltage can be sensed by using the 2 sensors. And the values are posted onto the GPRS. According to these values we can calculate the demand response. The interference of the wire is also calculated. if the values of the voltage and current are exceeding the threshold condition then the load can be tripped off.

This current and voltage sensors coming in energy meter. We will place energy meter instead of current and voltage sensors.

Micro Controller (8051), Ultrasonic Sensor, A/D Converter, 16X2 LCD.

ABSTRACT:

Real time peak detection can be implemented by using ultrasonic sensor. Ultrasonic Sensors also known as Transceiver which is work on a principle similar to radar.

Ultrasonic sensors generate high frequency sound waves and evaluate the echo which is received back by the sensor. Sensors calculate the time interval between sending the signal and receiving the echo to determine the distance to an object.

Ultrasonic sensors can be used for measuring height of the objects like buildings, vehicles etc. To measure the height of the object, the sensor measures the distance to the surface of the object.

Automatic Switching Of Induction MotorEXISTENCE:

The basic idea for the project is water level indicating circuit. The water level indicator is operated with the help of IC 555 timer. The IC 555 timer is provided with inputs as soon as the level of the water in the sump or reserve tank reaches to a predetermined level. As soon as the water touches the predetermined level, the water level indicating circuit indicates its users by alerting through a beep sound.

PROPOSAL:

The above existed idea of water level indicator circuit is used twice to indicate the levels in the sump as well as the overhead tank and the output of the two water level indicators are given as the input signals to microcontroller. The Microcontroller is programmed in such a way that if water level is above the minimum water level in lower tank, water gets pumped to upper tank and as soon as the upper tank gets filled, motor switches off automatically.

TOOLS REQUIRED:

  1. Two water level indicators Software required:
  2. An overhead and underground tank Keil C Software.
  3. 8051 Microcontroller
  4. Power supply

  FEATURES AND ADVANTAGES:

  1. Constant and reliable water supply.
  2. Functions with minimal or no human interface.
    3. Easy maintenance; install and forget for years.
  3. Low cost and it is absolutely affordable by all.
  4. Prevents dry running of motor and so water, energy, power not get wasted.

APPLICATIONS:

  1. Monitoring and controlling of water level in reservoirs, dams are important in applications related to agriculture, flood prevention etc.
  2. Domestic, industrial, medical fields etc.

CONCLUSION:

The main objective of the project is to automate process of water pumping in a tank, ability to detect the level of water in a tank, switch on/off the pump. Hence from our proposal of “Automatic switching of induction motor,” water wastage gets controlled by constant and reliable water supply.
