WIRELESS SECURITY SYSTEM
In our venture, we will detect any one is entering our place, to discover any gas spillage and fire in that place. Infrared transmitter which will emanate IR waves when we give control supply. The IR beneficiary will get the IR waves which were discharged from an IR LED. The flag will be enhanced with the assistance of an operational enhancer. At that point the operation amp yield will be given to an exchanging transistor.
At that point the yield will be given to a DTMF generator. By utilizing DTMF code generator we can produce sixteen sorts of DTMF yields. DTMF yield is Dual Tone Multi Frequency yield. The LPG gas sensor is settled close to the gas chamber. On the off chance that there is any spillage in the gas, the sensor faculties and sends the relating electrical yield flag to enhancer circuit. The intensifier circuit brings about further intensification of signs. The opened up flag is given to microcontroller. The microcontroller sends a flag to caution to demonstrate that there is a spillage of gas. Additionally, it sends the relating sign to the hand-off. The empowered hand-off works the solenoid valve. The valve gets shut by flag from the microcontroller.
On the off chance that there is any fire in that specific place the fire sensor detects it and sends the comparing electrical yield flag to intensifier circuit. The intensifier circuit brings about further enhancement of signs. The opened up flag is given to microcontroller. The microcontroller sends a flag to alert to show that there is a fire, we can distinguish that the fire caution is because of the expanded fire power. As indicated by that comparing sign is given to driver circuit and there happens an alert flag.
We can utilize sixteen IR sensor yields and we utilize touch sensor on dividers. In the dividers we settle an anxiety sensor when we push the divider it will create a voltage and afterward it opens up the low voltage into an ADC voltage level. At that point it will be given to a zero intersection locator. The exchanging transistor yield will be given to a FM transmitter, and after that the FM regulated waveform will be transmitted noticeable all around.
At the collector end we utilize single IC for getting the FM signals. A solitary IC i.e., something like CXA1019S will get the FM flag yield will be given to a DTMF decoder, the DTMF Decoder will translates the DTMF decoder will be especially valuable to recognize the sensor. The DTMF Decoder yield will be given to a microcontroller, and after that the DTMF code number will be shown in a LCD show. At that point the BCD yield will be shown. The caution circuit will enact the alert with the assistance of a driving circuit
