Hello sir, can i remove the GSM module instead attach a fan with turns on & off on human detection. @ uttam – Use AT commands to make a call and your problem is solved. Replace the AT commands for sending SMS with that of to make a call. @Bharath – You might have connected the sensor wrongly.
Quick Actions to shut down Fire – 90% of fire damages occur due to lack of early fire detection. A fire attack is usually silent and people will know about fire only when it has spread across a large area. SMS based Fire Alert system gives warning immediately to multiple mobile numbers and hence remedy actions can be taken quickly. This helps to prevent major damages and losses created by a fire accident.
About GSM Proteus Model
In Uart communication we connect TxD pin of first device to RxD of second one. Similarly Rxd of first one is connected with TxD of second one. After connection we set the baud rate of communication in software. Baud rate is simply the speed of communication between two devices communicating on Uart port.
It detects the signals from PIR sensor and sends commands to GSM Module accordingly. The serial pins of the Arduino are used in this project to communicate with GSM module. Normally we are using these phones to communicate with another person by calling, and SMS. In this project, we will use SMS technology to control home Appliances Wirelessly.
can one use sim800 in place
We hope that you liked this project and understand the concept behind it. If you have any doubts regarding this project then feel free to ask them in the comments section which is given below. Also, do check out more projects on Arduino and Raspberry Pi. Join the GND pin of the IR sensor with the GND pin of the Arduino. Attach the OUT pin of the IR sensor with the digital-7 pin of the Arduino. Now take an IR sensor and connect its VCC pin with the 5 volts pin of the Arduino.
A PIR sensor is used for sensing human presence. Controller calls to a predefined mobile number and at the same time it also sends a message to the same number via GSM Module. In this article,we are going to build a Fire Alarm System using Arduino, LM35 Temperature Sensor and GSM Module.

You can connect a pump or solenoid valve or whatever actuators you would like. The real point here is you can not connect any of these directly to arduino. You can only send a command to turn these devices ON/OFF from arduino. Inorder to power these devices, you should use a separate power supply and in most cases you should use a driving circuitry to drive these devices properly via arduino. For detection of the obstacles, we are using an IR sensor with Arduino.
Check the data sheet of your Module, you just need to find out serial communication pins Tx, Rx and power supply pins in your GSM module. Board 1’s pin 6 has been used to activate relay RL1. A loud siren can be switched on via the relay to scare the burglar or intruder away. Reed switches can be mounted on door frames of entry and exit doors. Small magnets should be mounted on the doors themselves. When a door is closed, the magnet and the reed switch should be in close contact with each other.
Transmitter is our cell phone
When the SMS is successfully sent to your phone a message will display on the serial monitor that ‘ message has been sent ‘. When the IR sensor detects something in front of it then the LED will turn on. Remember that, during this time a small motion in front of the sensor can create an error in calibration and the PIR sensor may not produce a reliable output. So, try to avoid very little movement in front of the sensor at the “warm-up” time. At the same time, The PIR sensor requires a “warm-up” time of 20 to 60 seconds to proper operation.
And you time period is good enough for completing this project. You can connect both LM35 and MQ2 in a single circuit to achieve this objective. You can write much easily in Arduino Programming Language.
And Rx and Tx pin of GSM module is directly connected at Tx and Rx pin of Arduino respectively. And GSM module is powered by using a 12 volt adaptor. 5 volt SPDT 3 relays are used for controlling LIGHT, FAN and TV. And relays are connected to arduino pin number 3, 4 and 5 through relay driver ULN2003 for controlling LIGHT, FAN and TV respectively. The security system can dial up to two phone numbers to alert you. It can also send text message to one of the numbers.
The switch can be placed in a hidden location outside the house, but it is not recommended. Leave the house after pressing switch S1 and turn off the alarm via SMS when coming home from work in the evening. A security system using the Arduino Bluetooth Camera and ultrasonic to detect that a stranger has entered house and capture a photo of him. It is a security system using 1Sheeld and its keypad, also included an ultrasonic that can detect if someone entered the home or not.
Attach the digital-10 pin of the Arduino with the TX pin of the GSM module. Join the RX pin of the GSM module with the digital-11 pin of the Arduino. You can also view the live working of this project by opening the serial monitor tab in the Arduino IDE.
This issue can be solved during thhe Arduino programming by ignoring the low output signals that have a short time duration than a predefined time. When there is any motion the output of the PIR sensor goes high. GSM module works with the Arduino with the UART protocol which is also known as the serial data protocol. So who is making their mind to make this awesome project by themselves they are in the right place.
This project is developed using 8051 microcontroller. It can be used to detect any intrusion in houses and offices and send the alerts on cell phones. Let us know how to develop this system, step by step. If fire occurs, room temperature will cross 45 degrees and an inner subroutine SetAlert() will be invoked. SetAlert() is the function that controls number of SMS alerts sent to each mobile number loaded in the program.
Its easy to use and its documentation is pretty straight forward. I worked with many other gsm modules build on SIMComsim900 chip. The Chinese cheap sim900 gsm modules are really hard to use and due to bad circuit designs their power requirements differ from each other. We supply power 5 volts to +ve pin and ground the Gnd pins. If you are from Pakistan, Bangladesh or India make sure you double-check the GSM module and purchase the unlocked version of the sim900A.
