Home Security System Using Cell Phone The project is about a home security system in which a cell phone is used as a device that will alert the owner of the house when an intruder enters the house.The owner just hav e to turn on the system s ystem before leaving his house.When an intruder enters the house in the absence of the owner the owner receives a call from a registered number which is the phone number of the haced mobile phone at his!her house.Cell phones have switches which when pressed short the terminals "gold plated# hence a number is seen on the screen so what i have done is put my cell phone number on speed dial on the phone i haced and when this number is pressed for a while i get a call. so basically what we r doing is a circuit that will short the phone terminals. when a intruder enters the house. $C %&'() is a dual op amp. The output of an op amp is difference of the input times the gain of the op amp. ie. it compares the * inputs. +,T- refer datasheet for more details about the $C. pin * of $C '() is threshold a potentiometer is connected to it so it forms a voltage divider and a particular voltage is set up at pin * which the op amp compares with voltage at pin '. to pin ' an %/0 is connected it behaves in following way. 1# when light shines on %/0 its resistance decreases hence a more positive voltage is set up at pin ' which forces the output to be high.hence high.hen ce there is a potential difference at the terminals of the number on the cell phone. *#when the light is cut off by the door which is opened by the intruder the %/0 resistance increases hence a more negative voltage is set up at pin ' which forces output to be low "2v#. in the e3uivalent op a mp circuit shown 4vid 4vid is appro5imately 2v when output is low and resistance 0o is very small hence the output is shorted to the ground thus shorting the * terminals of the cell phone. 1# 4 Cellphone having press buttons "i used an old one which i had#. *# 4 126 ohm resistor.

The cell phone i used is an old noia phone. 0emove the battery then remove the front cover then the eypad an then the transparent cover over the eys. ve /C voltage when the probes are on correct 9ve ?>ve terminals. $n my case the inner one was positive and the outer one negative. Solder a red wire to the >ve terminal and a blac wire to the 9ve terminal. 4ccording to the circuit diagram solder the circuit.a small dotted board is enough as there are hardly any components. +,T- the circuit remains same if a * legged $0 sensor is used. Solder the red wire from the cell phone ey to the output of the op9amp $C ie. at pin 1 and the blac wire to the ground. Solder the %/0 to a small piece of board and solder wires to it "%/0 do es not have polarity so it can be connected any way to the main board#.
Place the sensor and %4S-0 on opposite sides of a door. focus the %4S-0 on the Sensor such that %4S-0 falls on the sensor when door is closed and it is cut off from the sensor when door is open. $nsert any active sim card into the cell phone and register its number on your cell phone as @security@ or anything you lie.insert the battery and turn the cell phone on. turn on the power supply to the circuit. 4ny intruder will never come through a given door so every door in the house needs this circuit. the main boards will increase the times you have doors and the output of each and every op amp should be 4+/@ed "connected to inputs of 4+/ gate "/igital $C ;72)# and the final output should be connected to the mobile >ve terminal so only 1 cell phone is re3uired. http://www.instructables.com/id/Home-Security-System-Using-Cell-Phone/?ALLS!PS L"#$% - Single Supply 'ual (perational Ampli)iers Utili8ing the circuit designs perfected for Auad ,perational 4mplifiers? these dual operational amplifiers feature low power drain? a common mode input voltage range e5tending to ground!B--? and single supply or split supply operation. The %&'() series is e3uivalent to onehalf of an %&'*7. These amplifiers have several distinct advantages over standard operational amplifier types in single supply applications. They can operate at supply voltages as low as '.2 B or as high as '* B? with 3uiescent currents about onefifth of those associated with the &C1;71 "on a per amplifier basis#. The common mode input range includes the negative supply? thereby eliminating the necessity for e5ternal biasing components in many applications. The output voltage range also includes the negative power supply voltage.
