The world of automation has taken our homes, business sector and the industries by storm. Automation is a mechanization process where machines take over humans. Home automation system involves mechanized control of home appliances with the help of controller and use of diverse technologies. It is an energy saving option and is convenient. Life is simple with a home automation system. iOS and Android-based home automation systems are in vogue and can be connected to electrical and electronic devices at your home to be remotely controlled via wireless communication.
The working of a home automation system is executed through sensors, actuators and other controlling devices. The sensor is used to detect the light, temperature, motion and sensing elements. The data is sent to the controlling device and the sensors can be clubbed with thermostats or thermocouples, level sensors, current transformers, photo-detectors, pressure sensors, etc. It also needs additional signal conditioning equipment for communication with the main controller.
A PC, laptop, Smartphones, touchpad, tablets, etc can be used as controllers; these can be attached to programmable logic controllers capable of receiving information from sensors and control the actuators depending on the program. The load operations can help modify the program. The programmable logic controller facilitates connecting with actuators and sensors via output and input modules irrespective they are digital or analogue.
What are the different kinds of home automation?
The home automation can be implemented through wired or wireless controls. Based on this the home automation systems can be divided into three, power based, wired and wireless.
Power line home automation
The power line system is cost efficient and does not call for extra cable for information transfer but uses the existing power to transfer data. The existing cables can be used to control the interface for the home automation system. The system comes with large complexity and additional converter circuits and other devices. The Power Line option facilitates easy covering of the entire home. On the lows, Power Line may cause noise and needs filters, since it is not as advanced as wired or wireless automation. Some of the examples of Power Line Systems is X10 based technology which is growing in popularity as a protocol for home automation system.
Wired home automation
Using a main controller, the home equipments are connected. Actuators are used to connect to the main controller and the operations are completely computerized and are constantly in touch with the main controller. The wired communication relies on Cat 5 cables for communication. The wired system is connected to the control centre or the control system. These systems can be used in new homes or existing homes. This can be fixed easily and is a safe and reliable option to connect to the home automation system. The wired system is free of demerits yet it is not in great demand as people move towards wireless systems.
Wireless home automation
Wireless technology does not need wires or cables to run the home automation system. The installation is simple and less clumsy when compared to having wires all over your home. The reliability and ease of installation have made it an ideal choice for home automation. Wireless automation can be facilitation through advanced technologies like GSM, Wi-Fi, IR, Bluetooth, Zigbee, etc enabling remote operation. In GSM home automation the control is through GSM modem. Wireless systems using radio frequency instead of home network may not be compatible with other open networks. Before installing home automation system check the above factors.
Touch screen home automation
This type of home automation can be used in our homes as it is inexpensive. The light loads are attached to the microcontroller for control. In a touch screen home automation, the light loads are connected to the microcontroller to provide control. The user can send commands to control the loads. The microcontroller transfers the signals to the encoder circuit using software. The role of the Encoder is to convert data into binary format and transfer to RF transmitter and the receiver section receives the data.
The RF receiver decodes the information and transfers to a microcontroller. This way the command signal is sent to the optoisolator triggering TRAICs. The TRAICs controls the light loads. This way the home automation is possible with GSM.
So which type are you going to opt for?
