# Light bulb on/off with PIR sensor

# Introduction

In this project, using KiMu's Automate Advanced Kit, we are going to build a system that uses a relay switch and a PIR sensor to automatically turn on/off the light bulb based on the motion detection.

# Key skills/Learnings

  1. Problem Solving
  2. Logical Thinking
  3. Working of relay switch & PIR sensor

Note: All activities which involve main voltages (voltage greater than 50V) should be performed under adult supervision.

Step 1: Connect the light bulb to the power plug with a wire(black).
Step 2: Connect one end of the relay to the light bulb with wire(red) and the otherend to the power plug.
Step 3: Connect PIR sensor to U2 connector of the sensor board.
Step 4: For the connection of Relay, Sensor board and power refer to below image.

# Programming with Automate App

# Configuring the app - Remote controls setup

The light can be switched ON/OFF based on a motion in the room using a PIR sensor.

STEP 1- OFF
STEP 2 - ON


Note: Automate can be controlled using a cable by selecting the cable option instead of Wi-Fi under the remote option.

To upload the program, see How to upload the program to the Control Unit with Automate App?

The light bulb can be switched on/off based on the motion, after uploading this program.
