Based on ultrasonic ranging 8051
no vote
Application background THIS CODING PART IS BASED ON DISTANCE MEASUREMENT USING ULTRASONIC SENSOR.WE HAVE USED RF TRANSCEIVER TO SEND THE DISTANCE THROUGH RF TO REDUCE THE SPEED OF THE MOTOR. THIS APPLICATION IS USED TO AVOID ACCIDENTS.THIS ULTRASONIC SENSOR PLAYS AN IMPORTANT ROLE IN THIS PROJECT. Key Technology THIS PROJECT IS BASED INTERFACING ULTRASONIC SENSOR WITH 8051.WE NEED TO CONVERT THE ANALOG VALUES INTO DIGITAL AND THE CONVERTED VALUES IS SENT TO THE 8051.WE NEED EXTERNALLY AN ADC CONVERTER LIKE 0804 IC.SINCE 8051 DOESNT HAVE AN IN BUILD ADC CONVERTER.I HAVE USED RF TECHNOLOGY.

Application background This is a project based on Library management using RFID technology .I have used PIC controller to interface RFID. The RFID is used as a login for a particular person who enters the library and for logout purpose also in this project.When the user wants to place a book in the library shelf ,to indicate the correct shelf I have used a green LED and to wrong shelf I have used red LED .This is indicated by the RFID tag placed in each book .When the tag ID matches with the ID in the controller placed in the shelf,green LED glows else red LED glows.This is used for shelf management in Library . Key Technology The software consist of Embedded C which is developed using MPLab IDE v 8.63 from microchip .The software

Temperature monitoring with GSM interfaced with pi
no vote
Normally the condition change in refrigerators are not monitored by us,it depends on the particular items kept in fridge. This project is based on Temperature monitoring in refrigerators. When the temperature falls below -10 degree Celsius the temperature sensor kept in the fridge alerts the PIC controller.Since below -10 degree considered as over cooling, t he PIC send a message to the user through the GSM as ABNORMAL TEMPERATURE. When a normal temperature it doesnt response. In this project we have used PIC16F877A controller interfaced with GSM and temperature sensor.We have used AT commands for sending message to the user. The user receives the message with Exact temperature in the refrigerators ,so he can maintain it correctly.
