Introduction:

In this project we show that how we use the Mobile as an electronics eye. With the help of mobile phone we check and examine the position of the house automatically. In this logic we attach some sensor with the mobile and if there is any miss happening then mobile is automatically dial a number deliver the voice message to the received end. All these logic is to be divided into few parts.



Action of Steps:

• Sensor unit.
• Microcontroller interface.
• Switch on the mobile.
• Dial a number.
• Transfer the message on the mobile.
• Switch off the telephone line after sending the message.


Working:
Intruder sensor:


The infrared intruder sensor is used to sense some unknown person like thief entering in your house without your permission.
In the infrared sensor we use IC 555 as a main component. Pin no 4 and pin no 8 is connected to the positive supply. Pin no 1 is connected to the negative voltage. One capacitor is grounded from the pin no 5 for noise cancellation. Output is available on the pin no 3. Sensor is connected to the pin no 2.

In the case of infra red sensor Pin no 2 is negative bias through the 33k ohm resistor and pin no is positively biased through the photodiode. One infrared transmitter led is focused to the photodiode. Infra red led is directly connected to the positive and negative supply through the 330ohm resistor.

In normal stage when light is focusing on the photodiode then pin no 2 is positively biased photodiode. If pin no 2 is positive then negative output is available on the pin no 3. Now when any body interrupts the light then there is no light on the photodiode and pin no 2 is now gets its voltage from only 33 k ohm resistor. If pin no 2 is become negative then output is shifted to the pin no 3.


Smoke sensor:
The working and the circuit diagram of smoke sensor is same as intruder sensor except we have placed LDR sensor in place of IR sensor and High brightness LED in place of IR transmitter.

In normal stage when LED light is focusing on the LDR then pin no 2 is positively biased photodiode due to low resistance of LDR. If pin no 2 is positive then negative output is available on the pin no 3. Now when smoke interrupts the light then there is no light on the LDR and pin no 2 is now gets its voltage from only 33 k ohm resistor due to high resistance of LDR. If pin no 2 is become negative then output is shifted to the pin no 3. When positive output is available on the pin no 3 and with the help of this voltage NPN transistor is on and npn transistor provide a negative voltage as a pulse to the microcontroller (Pin No39).
