5/7/2023 0 Comments Home control remoteHome automation is an in demand concept where a single device will control different appliances of a home. Working of Arduino based Home Automation using TV Remote More detailed connection can be found in the circuit diagram. all we need to do is to connect the 4 inputs on the relay board to 4 digital I/O pins of Arduino. Since the board has all the necessary components like transistors, LEDs etc. We are using a 4 – channel relay module in this project in order to control 4 different loads. The output pin is connected to Pin 11 (or any other digital pin) of Arduino UNO. The VS pin is connected to the 5V supply. It is a three pin device where the three pins are GND, VS and OUTPUT. The main component of the project is the TSOP1738 receiver. The design of the circuit is explained below. How to Design Arduino based Home Automation using TV Remote Circuit?įrom the circuit diagram, it is clear that the design of the circuit is very simple and requires very few connection. The remote has all the numeric keys, volume up – down, channel up – down, menu and some additional keys. The necessary components like power on LED, switching transistor, base current limiting resistor, Relay on LED, flyback diode and male headers for power and input connections are already embedded on the board.Ĭaution: We should be very careful when using a relay with AC mains supply.Ī standard mini remote control is used in this project to give the various key inputs. In this project, a 4 – channel relay board is used to control four loads. It consists of a Photo detector and signal demodulator in a single package and the output can be directly used by a microcontroller.Ī Relay helps in controlling a large appliance with the help of a microcontroller. TSOP1738 is a Receiver module for IR Remote controls with a carrier frequency of 38 KHz. If the requirement is to control more number of devices, boards like Arduino Mega can be used. UNO has 13 digital I/O pins and hence, it is possible to control 13 different devices at once. Working of Arduino based Home Automation using TV RemoteĪrduino UNO forms the main controlling part of the circuit.How to Design Arduino based Home Automation using TV Remote Circuit?.The project is based on Arduino UNO and more details of the project are mentioned below. For example, a TV remote control unit can only be used for that corresponding TV.īut in this project, we have designed an Arduino based Home Automation using TV Remote, where a single remote is used to control 4 different devices (possible to control more devices). The main feature of a remote control is that it is specific to a device. They help us operating an appliance like TV, Air Conditioning, VCR, etc. Remote controls are one of the commonly found devices in almost all homes. In this project, a remote control is used to control (simply ON and OFF) several appliances or devices, thus achieving a simple home automation system. Home Automation is a concept where a single device is used to control many aspects of a home like switching on and off different appliances, monitoring temperature, fire alarms, garage doors etc. Arduino based Home Automation using TV Remote is a simple project, where an old TV Remote is used to control different appliances.
