This motion sensor based security system detects any trespassing that occurs in the range of the motion sensor. Depending on the movement of the object it sends a signal to the arduino board. This SMS sending gives the user a great safety feature remotely. It also has one arduino burglar alarm in the system. Because there is some settling time involved in learning its environmental conditions. This time is approx seconds. During this time there should be a slow motion in sensors field of view. PIR sensor has a range approx 20feet and depends on environmental conditions. It is designed to adjust in slowly changing conditions this generally happens when day progresses.

It responds by giving a high signal on the sudden change in its environment. In the previous tutorial, we have interfaced PIR motion sensor and piezo buzzer with the arduino. And the interfacing and programming are quite easy to understand. The interrupt in this project makes it very reliable in detection of PIR Sensor. PIR motion sensor is connected with arduino digital pin 2 using the interrupt feature.

The piezo buzzer is connected to the arduino digital pin 13 for indication of the alarm. The main feature of this arduino burglar alarm project is to send the SMS to the mobile phone of an owner when it detects any trespassing or movement in the PIR sensor area. You can use the SIM or equivalent. The second important part is using interrupt we are reading the motion sensor value.

So the question is why to use the interrupt. An interrupt is a great way of serving the input connected to the CPU like arduino. Depending on the importance of the input we use the interrupt. Using interrupt, the CPUs execute its normal program which is less important. And keep an eye on the most important input like fire alarm input, smoke sensor, and burglar alarm. And CPU wants never miss reading this input while executing the other low priority code.

By connecting this input to the interrupt pin and programming the CPU for that. If input occurs on the interrupt pin, CPU serve it first by pausing other less important code.

Microcontroller Based Home Security System with GSM Technology

As we have used the interrupt to read the motion sensor input. When arduino receives the signal from the motion sensor. Fig 3: When the GSM modem and computer are interconnected, there is communication over the mobile network. The GSM modem used for the work is configured using standard AT commands that can carry out operations of conventional phone. The major usefulness of the module is its ability to interface with other circuit elements like the microprocessor hence making it possible to embed it with other system.

Table 1: AT is the abbreviation of Attention. Every command line starts with "AT" or "at". That's why modem commands are called AT commands. Table 2: It computer-on-a-chip and contains all the elements of computer. It has built-in functions to minimize the need for external circuits and devices to the design in the final applications. As an output port, each pin can sink eight TTL inputs. When 1s are written to port 0 pins, the pins can be used as high impedance inputs.

In this mode, P0 has internal pull ups. External pull ups are required during program verification. When 1s are written to Port1 pins, they are pulled high by the internal pull ups and can be used as inputs. As inputs, Port 1 pins that are externally being pulled low will source current IIL because of the internal pull ups. Port1 also receives the low-order address bytes during Flash programming and verification. When 1s are written to Port2 pins, they are pulled high by the internal pull ups and can be used as inputs.

As inputs, Port 2 pins that are externally being pulled low will source current IIL because of the internal pull ups.

In this application, Port 2 uses strong internal pull ups when emitting 1s. When 1s are written to Port3 pins, they are pulled high by the internal pull ups and can be used as inputs. As inputs, Port 3 pins that are externally being pulled low will source current IIL because of the pull ups.

Port 3 also receives some control signals for Flash programming and verification. RST Reset input. A high on this pin for two machine cycles while the oscillator is running resets the device. This pin drives High for 96 oscillator periods after the Watchdog times out. Note, however, that one ALE pulse is skipped during each access to external data memory. Otherwise, the pin is weakly pulled high. Setting the ALE disable bit has no effect if the microcontroller is in external execution mode.

Note, however, that if lock bit 1 is programmed, EA will be internally latched on reset. EA should be strapped to VCC for internal program executions. This pin also receives the volt programming enable voltage VPP during Flash programming. XTAL1 Input to the inverting oscillator amplifier and input to the internal clock operating circuit. If the smoke is present IR signal is attenuated due to presence of smoke. IR receiver conductivity is converted into voltage and compared with threshold voltage set by variable resisters.

If smoke is present, conductivity of IR receiver is reduced and if it falls below threshold then it configures a certain pin of microcontroller high. At this point when power is supplied the microcontroller remains or stays in a low state waiting for an input signal. Port 2. Port 0 is used as output port from microcontroller to input of the buzzer. When an input pass through anyone sensors input, this is sensed by the microcontroller is interrupts.

As such the microcontroller stops other software program running. It goes to access the address bus of the input signal and loads the program stored in the address register, after loading, it sends to control register, compute the signal based on the stored program and runs the instruction. It sends out streams of instruction to the output register or ports.

The sensor unit senses temperature, gas, obstacle and touching. The sensor is responsible to sense all detection value and changing it into energy it could be received through microcontroller. The controlling unit recognizes up on information from sensor and sends to GSM modem. Then GSM modem sends the detected signals to the users, particularly to the mobile phone of the house owner. On the other hand if intrusion and gas or fire is occurred the buzzer will provide the sound and microcontroller will check the result and sends to the GSM modem then through GSM network architecture the owner of house receive the message containing the status of their home.
