(Smart Home Monitoring And Fire Alert Solution) :-
Creating a smart home monitoring and fire alert solution involves integrating various sensors, devices, and technologies to enhance safety and provide timely alerts. Here's a general outline of the components and features you might consider for such a system
(Components) :-
- Node MCU Microcontroller
- Oled
- MQ135
- Flame Sensor
- Dht11
- Buzzer
- Voltage Regulator
- SIM800 #Adaptor 9V
Node MCU is predicated on the Esperessif ESP8266-12E Wi-Fi System-On-Chip. It is based on Lua-based firmware and is open-source.
- The frequency ranges from 100Hz to 1KHz:-
- Operating Voltage: 2.5 to 3.3V
- Operating current: 800 mA 3.3V
- 600mA on-board voltage regulation
The DHT11 is a commonly used Temperature and humidity sensor that comes with a dedicated NTC to measure temperature and an 8-bit microcontroller to output the values of temperature and humidity as serial data.
- Operating Voltage: 3.5V to 5.5V
- Operating current: 0.3mA (measuring) 60uA (standby)
- Output: Serial data
- Temperature Range: 0°C to 50°C
- Humidity Range: 20% to 90%
- Resolution: Temperature and Humidity both are 16-bit
- Accuracy: ±1°C and ±1%
The MQ-135 Gas sensor can detect gases like Ammonia (NH3), sulfur (S), Benzene (C6H6), CO2, and other harmful gases and smoke.. This threshold value can be set by using the on-board potentiometer. The analog output pin, outputs an analog voltage which can be used to approximate the level of these gases in the atmosphere
- Operating Voltage: 2.5V to 5.0V
- Power consumption: 150mA
- Detect/Measure: NH3, Nox, CO2,Alcohol, Benzene,Smoke
- Typical operating Voltage: 5V
- Digital Output: 0V to 5V (TTL Logic ) @ 5V Vcc
- Analog Output: 0-5V @ 5V Vcc
4. Flame Sensor:-

A flame-sensor is one kind of detector which is mainly designed for detecting as well as responding to the occurrence of a fire or flame.
The features of this sensor include the following
- Photosensitivity is high
- Response time is fast
- Simple to use Sensitivity is adjustable
- Detection angle is 600
- It is responsive to the flame range
- Accuracy can be adjustable
5. Buzzer:-
An audio signaling device like a beeper or buzzer may be electromechanical or piezoelectric or mechanical type. The main function of this is to convert the signal from audio to sound. Generally, it is powered through DC voltage and used in timers, alarm devices, printers, alarms, computers, etc. Based on the various designs, it can generate different sounds like alarm, music, bell & siren.
6. OLED Display:-
OLED’s are the future of displays, as they possess some of the greatest advantages over both conventional display technologies of LCD’s and LED‘s.
This 0.96″ OLED Display Module offers 128×64 pixel resolution. They are featuring much less thickness than LCD displays with good brightness and also produce better and true colors.
This OLED Display Module is very compact and will add a great ever user interface experience to your Arduino project. The connection of this display with Arduino is made through the I2C(also called as IIC) serial.
7. Voltage Regulator:-
LM2596 DC-DC Buck Converter Adjustable Step Down Power Supply Module
Specifications:-
SIM800L is a miniature cellular module which allows for GPRS transmission, sending and receiving SMS and making and receiving voice calls. Low cost and small footprint and quad band frequency support make this module perfect solution for any project that require long range connectivity. After connecting power module boots up, searches for cellular network and login automatically. On board LED displays connection state (no network coverage - fast blinking, logged in - slow blinking).
Specification:-
All Sensor Is Integrated with Esp8266 on zero PCB and enable the wifi of Node MCU.Basically First Node MCU Show the HOTSPOT and you can configure the Wifi SSID and Password .We Also Use SIM800 Module so that you can insert Sim and you can send sms for any person.
In our project we will write the code on Arduino Platform . The data is show on locally in Oled Display and by the help of wifi it connect with cloud by mqtt broker. Mqtt Broker is the bridge between device and cloud platform and we will show the data on NODE-RED . Node-RED is a flow-based development tool for visual programming developed originally by IBM for wiring together hardware devices, APIs and online services as part of the Internet of Things. Node-RED provides a web browser-based flow editor, which can be used to create JavaScript functions.You Can Make Dashboard so that you can also check the data.
(Working) :-
Working is quite simple first you will insert airtel,vi sim except jio sim because our module support only 2G sim and then you can power up the device and config the wifi it is one time if the wifi password is change or your network is change then you can again configure wifi . when wifi is connected then data will show you on cloud and Oled display.When Fire is detected then it will show on Oled display and Buzzer get on and it also show you on cloud dashboard and it also send alert sms by the help of gsm module
How Config The Wifi In Esp8266 :-
(Dashboard Flow) :-
This is our flow in Node-RED to make the UI /Dashboard . In this we select mqtt in node and gauge node and one is text node .You can run node-red locally in your computer as well.
