Metal detector project is a portable electronic device which detects the presence of metal nearby. Metal detectors are useful for finding metal inclusions hidden within objects, or metal objects buried underground. They often consist of a handheld unit with a sensor probe which can be swept over the ground or other objects. If the sensor comes near a piece of metal this is indicated by a changing tone in earphones, or a needle moving on an indicator. Usually the device gives some indication of distance; Continue reading Metal Detector
GSM based Locker Security System with EEPROM to protect the locker against theft or misuse by other person. This project is controlled by micro controller 8051 with GSM modem. There is a 3×4 matrix keypad to enter the password for operate the locker. If any other person or theft will try to enter the password and if he tries three times with wrong password then our system automatically sends the theft alert message to administrator using GSM modem. There is 16×2 character LCD display which displays all the information like password matched or not, sending theft alert message etc. Continue reading GSM based Locker Security System with EEPROM
As name suggested, Home Automation using Mobile is going to be used for control the home appliances. It enables you to control home appliance like Bulbs, Fan, and Television etc with the pressing of your mobile key from anywhere. There are no needs of specific remote for this, user can use any to control these appliances. So if you forgot to switch OFF the lights or other appliances while going out, it helps you to turn OFF the appliance with your cell phone.
Multiuse Text Messaging by RF is the exchange of brief written text messages between two or more portable devices. Secured wireless communication plays an important role for military, office, industry. Multiuse Text Messaging by RF project is specially made for wireless communication. It doesn’t need any networking service. As many times we need to communicate within a campus or a small area. So, this project can use for this purpose without paying messaging bill. The major point of this project is that it is secured wireless communication. Transmitter encodes the message before sending it which couldn’t decode easily by any receiver. Our receiver circuit knows the decoding format so it easily decodes and user can read the message. In this way user can get securely communicates with each other.
This project is used to communicate or transmit a text message from one place to another place through wireless. The text message is encrypted by using the Microcontroller and the encrypted message was transmitted through wireless Zigbee. At the receiver end the signal was received by the standard receiver and the analog signal was fed to the Microcontroller and it was decrypted by the Microcontroller and the message was displayed over the LCD display.
