Home Automation using ESP8266 and Touch Sensor

This is a two-channel touch & two-channel wifi home automation project. This project can control four appliances via two touch sensors and a smartphone(wifi). We have built many such project, here are some example

Component Required for Home Automation

Home Automation Components

Project Used Hardware

  • Blank PCB,
  • BC547 Transistor,
  • Resistor(220ohm),
  • Diode(1N4007),
  • Relay(5volt),
  • 3pin Terminal, 
  • SMPS(5volt),
  • Touch Sensor(ttp223),
  • ESP8266 12E,
  • AMS11179(3.3v.),
  • 10k resistor

Project Used Software

  • arduino ide, 
  • blynk(legacy)

Project Hardware Software Selection

To set-up the Blynk app, add switches and then first switch-V1 & second switch-V2. To set-up the code, change wifi ssid, password & change auth token given by blynk.

To program the ESP8266 12E module, you can use different types of programmers like witty cloud development board, nodemcu, and CP2102 USB to TTL converter.

//write the wifi name,password and auth token given by the blynk.
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>
int relay1 = D1;
int relay2 = D2;
char auth[] = "xxxxxxxxxxxxxxxx";
char ssid[] = "xxxxxxxx";
char pass[] = "xxxxxx";
  int pinValue = param.asInt();
  digitalWrite(relay1, pinValue);
  int pinValue = param.asInt();
  digitalWrite(relay2, pinValue);
void setup() {
  pinMode(relay1, OUTPUT);
  pinMode(relay2, OUTPUT);
  Blynk.begin(auth, ssid, pass);
void loop() {
