Introduction: Build Your Own IOT Device !!
Please Do vote :)
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.!
Arduino - 1
vibration sensor -1
for pressure we have used potentiometer of 10Kohm-1 .
breadboard if necessary !!
Step 2: Connection !!
Arduino A0- Fire sensor
Arduino A1- LM35
A2 - Pressure sensor
A5-Vibration sensor !
ch-pd and vcc to 3.3v
Step 3: Coding !!
#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
// You should get Auth Token in the Blynk App
// Go to the Project Settings (nut icon).
char auth = "YourAuthToken";
Serial.begin(9600); // Set console baud
EspSerial.begin(9600); // Set ESP8266 baud
Blynk.begin(auth, wifi, "ssid", "pass");
Step 4: 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
select board type
copy auth token & insert into your program
connect all the sensors !!
and run app
