Smart home automation using microcontroller
- 1. SMART HOME AUTOMATION USING MICROCONTROLLER Presented by: V.Karthikayan R.Rajasarma
- 2. INTRODUCTION: • Our paper is about home automation with the use of power saving tequnice. • Automation is noting but closed loop operation with the help of microcontroller and sensor. • In the automation we are using Aurdino controller with * Temperature sensor * Ultrasonic sensor * PIR sensor * Water flow sensor * LDR
- 3. SENSORS: Temperature sensor is used and measured for temperature. It works is monitoring the temperature value. It used IC number is LM 35. PIR (passive infrared sensor ) is a identified sensor. It is identify the living things only. It used IC number is HCS-R501. ULTRASONIC sensor mainly used for measuring the distance. It has another used for position sensor. It model number is HC -SR04.
- 4. Water flow sensor it measured for the liquid type materials. It worked for maximum 5V DC supply. It measured for 30lit maximum. Sensor number is YF-G1. LDR (Light depend resistor) is a light control variable resistor. Brightness value is high resistance value is high because current flow is low. Brightness value is low resistance value is low level because current flow is high.
- 5. CONTROLLERS: ARDUINO UNO is a one type of micro controller. It has worked for constant voltage 5V dc supply. It used for programming language in embedded system. It has 14 digital pin is used and analog input pin is 6. The transmitted pin is (TX) and received pin is (RX). A 3.3 volt supply generated by the on board regulator. Maximum current draw is 50 mA
- 6. GSM (Global System for Mobile Communications) It used through the SMS information . Connect with ARDUINO, RASPBERRY PI, NODE MCU, ESP 8266, etc. Best suited for GSM based Microcontroller Projects (better than SIM300 ). The transmitted pin is (TX) and received pin is (RX). It used for the 2G and 3G signals only .
- 7. Ethernet is a family of computer networking technologies. It has a one type of controller. It has a LAN (Local area network) or inter net device control and monitoring. It has send and Receive the signal for maximum ranges. That maximum level Temprature is 0 to 70 °C .
- 9. HomeAutomation(HA) With HA you control and monitor devices and information is given. Triggerthings basedon time. Measured for temperature , lightning and etc. Security •Monitoring doors andwindows Fire, smoke,water. Entertainment • It used for control with TV , AMPLIFIER , HOME THEATER and etc..
