DTMF Based Robot for Security Applications
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 3
Abstract
The main idea is to implement microcontroller based application which can provide security like video monitoring, fire safety, bomb detection using metal detector and identifying nearby obstacles using ultrasonic sensor. For this we are using DTMF [Dual Tone Multi Frequency] technique which is as in build feature in some mobiles and GSM technology. The sensors used for indicating the variations in the surroundings and are interfaced to the micro controller along with a mobile which supports DTMF by using DTMF decoder on the receiver side. GSM modem is also interfaced to the controller through a driver IC max232 for serial communication. The controller will monitor the present state of these sensors and if there is any change in the state of the sensors, it will send the message to the predefined mobile number. Then we will establish a call between the controlling mobile and the remote mobile. Now any key pressed on the mobile will generate a frequency, which can be heard on the mobile placed on robot. That frequency can be detected by controller by means of DTMF decoder. Keys assigned for control can be User Defined for controlling like robot movements. Here we are using a mobile phone in which the Android app is installed in it through which the camera is linked to the Android web camera via Wi-Fi in laptop and video is monitored in laptop and we are controlling the rotation of the phone to see all sides.
