Tv Remote Controlled Home Automation

Introduction: Tv Remote Controlled Home Automation

About: I am an electronics hobbyist and I love to share my works with others

in this tutorial I am going to show you how to make simple home automation using tv remote

Step 1: Componets Needed

  • BC547B
  • Transistor BD140
  • 1N4007
  • 1K resistor
  • CD4017
  • TSOP RELAY
  • 100UF capacitor

Step 2: Circuit Diagram

Step 3: Working

this circuit uses a TSOP1738 IR receiver module in normal condition, the output pin of the IR module is High, which means the transistor (bd140 PNP) is at logic Low. but when ir signal fall to tsop sensor the output of tsop goes low and transistor will turn on. the output of the transistor is connected to a toggle switch constructed with cd 4017 counter ic

Step 4: Happy Making
