This is a simple project which you can build it in 30 minutes ,but it has lot of applications and advantages ,this project is basically an Internet of things project ,here I used a sensors like Vibration, pressure (pot),fire,temperature (lm35) and esp8266 n Arduino uno .this sensors will send the data through WiFi module and Arduino to the blynk app which is installed on an Android app which can be used to view sensor's data over the internet.

Step 1: Components Required.!

Picture of Components Required.!

Arduino - 1


LM-35 -1

vibration sensor -1

fire sensor-1

for pressure we have used potentiometer of 10Kohm-1 .

few jumpers

breadboard if necessary !!

Step 2: Connection !!

Picture of Connection !!

Arduino A0- Fire sensor

Arduino A1- LM35

A2 - Pressure sensor

A5-Vibration sensor !

and esp8266

ch-pd and vcc to 3.3v
gnd -gnd

Step 3: Coding !!

Picture of Coding !!

/#define BLYNK_DEBUG
#define BLYNK_PRINT Serial // Comment this
// Set ESP8266 Serial object
#define EspSerial Serial1
// This can be a SoftwareSerial object (rememb
//SoftwareSerial EspSerial(2, 3); // RX, TX
ESP8266 wifi(EspSerial);
// You should get Auth Token in the Blynk App
// Go to the Project Settings (nut icon).
char auth[] = "YourAuthToken";
void setup()
Serial.begin(9600); // Set console baud
EspSerial.begin(9600); // Set ESP8266 baud
Blynk.begin(auth, wifi, "ssid", "pass");
void loop()

Step 4: Blynk App !!

Picture of Blynk App !!

Blynk was designed for the Internet of Things. It can control
hardware remotely, it can display sensor data, it can store
data, vizualize it and do many other cool things.

open the app

create account

select board type

copy auth token & insert into your program

connect all the sensors !!

and run app

Step 5: Connection !!

where do I connect the sensors

can you post a picture of how the project looks as finished? And can you show how to control it remotely rather than with wifi module.
