We use so many appliances at home that often it becomes a headache to keep track as to whether everything is switched off or not, especially after stepping out of the house. Home automation or smart home is a key that keeps you away from all these worries by automating the appliances and connecting them to a common network.It is basically a home where everything including the lights, alarm clocks, television, doors, windows, blinds, heating and cooling systems can talk to each other. Not only this, all such automated devices also receive as well as interpret their owner’ instructions and then behave accordingly. The success of home automation, to some extent, relies on the availability of smartphones as they can be easily connected to other devices through the internet and are highly portable.
Clap Operated Remote Control for Devices
This circuit is based on two commonly used IC that is NE555 timer and CD4017 IC with few more components. 555 timer IC wired as an monostable oscillator. In this circuit NE555 monostable generates a clock for the circuit, which provide a oscillating wave to the output pin 3 of IC1. Monostable or one short multivibrator has only one stable state and we have to trigger it externally to return it back to its original state. CD4017 is a CMOS counter/ divider IC . It take clock signal from the clock input and turn on the 10 output in sequence, each time when it receives clock input pulses. It is the most popular IC and extremely useful in various project like Light Chaser, Matrix Die. In order to understand the working of IC one must know about its individual pin.
How to Decode RC-5 Protocol Used in Philips TV Remote Control
RC-5 protocol was developed by Philips in the late 1980s and it is still most widely used. A remote control is a component of an electronics device most commonly a television set originally used for operating the device wirelessly from a short line-of-sight distance. Commonly, remote controls are Consumer IR devices used to issue commands from a distance to televisions. Remote controls for these devices are usually small wireless handheld objects with an array of buttons for adjusting various settings such as television channel, track number, and volume. Most of these remote controls communicate to their respective devices via infrared signals.
Remote Control for Devices using Cell Phone
Many of us face problem when we out of our home like if we want to on the motor, so that when we reach home water will be filled in over head tank or we want to on other appliances like light fan etc. Hence to solve this problem we have describe a simple circuit which will on your device or appliances remotely and it will become off automatically after preset time interval. Many circuits have been developed so far to solve this problem but main advantage of this circuit is uses readily available components and this circuit is not expensive as well because this circuit is made using without microcontroller.
Remote control for various industrial applications
The figure shows the block diagram of complete communication system, which can be divided into three main sections; namely a master unit, remote unit and signal transmission through free space optics. The remote unit is used to control the master unit. The hierarchy of operation is as follows.For Remote Module.: DTMF Keypad will provide control signal to DTMF Encoder; DTMF Encoder generates the tone frequency signal; IR Transmitter converts the above into a light signal.Free Space Optics: IR Signal generated by IR transmitter to Master Unit through Free space; IR Receiver reads the light signal and converts it into the tone frequency signal; DTMF to BCD decoder convert the above signal to BCD;De-multiplexer provides control signal for required switching.
Remote Control For Home Appliances
Using remote control for home appliances is a great choice. They can be used to on and off the appliances like TV, AC, DVD player, motor etc with the help of our TV remote. LEDs can be used to on and off. IF LED1 is glowing, it means device is off and if LED2 glows than the device connected is on. This is a low cost circuit is based on the CD4017 counter IC which receives trigger pulse from IR sensor and switch on the relay. Since, the device is connected to relay it is also switched on.Upon receiving the second pulse motor become off. You can control your toy car from 5 meters range. This is a simple circuit based on infrared sensor IC TSOP1738. TSOP1738 contains photo detector and pre-amplifier both in one package. It is a three terminal device. Pin 1 is for ground, Pin 2 is for power supply and pin 3 is used as output.
Insight: The internal working of a remote control
The Oxford Dictionary defines a remote control to be a “control of a machine or apparatus from a distance by means of radio or infrared signals transmitted from a device”. So, when we decided to go inside a conventional remote control, we were stuck: which one to take? There are those for LCD TV, others for gaming consoles, for the car entertainment systems and some that work for all kinds of systems. At the very first sight, one can notice difference in designs, features, the manner they are powered and several such features. But upon giving a slight thought, it is easy to understand that all the remotes are performing the same basic task: controlling outputs of an electric/electronic device. So, here we are, with a Sony RMGA020 LCD TV Remote used for their 32 inch KL television series. Interestingly, Sony calls their remote to be “Remote Commanders”. Since the trend nowadays is to equip remotes with a hoard of features and create the main gadget as simple as possible, calling them “Remote Commanders” is fair enough.
Remote Control for Motor
The circuit described below is used to on and off the motor just by clicking your TV or AC remote. This low cost circuit is based on IR sensor, transistor with few more components to “on” the relay and a motor is connected with the relay which also become “on”. After receiving the second pulse motor become “off”. You can control your motor from 5-7 meters range. It can be operated with all most all the remotes present in home as it works on 38Khz frequency. You do not require to move from your place, just press the remote device become “on” and “off” respectively by getting signals from remote. The circuit also provides you the visual indication (“on” or “off”) of the device with the help of LED.
