Definition

Cellular through remote control switch implies control of devices at a remote location via circuit interfaced to the remote telephone line/device by dialing specific DTMF (dual tune multi frequency) digits from a local telephone. This project Cellular through remote control switch has the following features

1. It can control multiple load (on/off/status each load)
2. It provides you feedback when the circuit is in energized state and also sends an acknowledgement indicating action with respect to the switching on of each load ....etc

IR SWITCH AND REMOTE CONTROL


CIRCUIT DIAGRAM :
IR DETECTOR CIRCUIT :

1. The detector circuit uses an IR detector TSOP 1738 commonly available in the market. This is tuned to detect IR pulses at 38Khz frequency and also it tuned not to respond to stray IR coming from natural light or any other source like tube light etc in your home.
2. Since IR detector can produce a sequence of signals when it detects IR radiation we are using a buffer which will, sort of accumulate signal re ....etc

Abstract This paper demonstrates a novel method which
enable users to control their home appliances and systems from
remote using a cell phone-based interface. To access the
control unit, the user should send an authentication code
(DTMF) along with the required/desired function/action to
his/her home control system via Global Sytem for Mobile
communication(GSM). Upon being properly authenticated, the
cell phone-based interface at home (control unit) would relay
the commands to a microcontroller that would perform the
required functio ....etc
