Editor's note: This review has been updated to account for the August Connect WiFi accessory released on 2/13/2015. The August Smart Lock nails most of the things I'd want in a connected door lock. It's easy to install. It looks good (yes, despite its size) and the August app (in iOS, at least) gives you the right balance between flexibility and keeping things safe and simple. The fact that it works with your existing deadbolt is also a plus. The $250 asking price (international availability pending) puts August on the more expensive end of the smart-lock spectrum. The August Smart Lock also suffers from the same limitations as other connected locks. Because it's a Bluetooth-only device, controlling the lock with your phone when you're out of range requires either a compatible third-party hub or August's new $50 Connect accessory that you'll need to buy separately. Bluetooth also means you'll suffer from minor but still annoying lag when you first open the app to interact with the Smart Lock.

If the lag means you won't likely swap your physical key out for the August and a connected smartphone, this lock still gets enough things right that it's become our new favorite automated door control. We will certainly see more connected locks come to market over the next few years. This is the one they need to beat. We've reviewed a handful smart locks , and all of them but August involve wholesale replacement of your lock hardware. In the case of the August Smart Lock, it's designed to use your existing deadbolt and keyset, replacing only the thumbturn on the inside face of your door. For the most part the complete lock sets have been fine, but we ran into trouble when we reviewed the Kwikset Kevo . The Bluetooth-based functions of that lock work well enough, but the deadbolt is not as secure as the company claimed. As we said in our review last year, the Kevo's Bluetooth tech is impressive, but the product as a whole suffers since you can't separate it from the lock hardware. Because the August is a retrofit product, the quality of the deadbolt is up to you.

As long as your existing lock uses one of the 100 or so compatible deadbolts on this list, you can add the August lock to it. Read the directions with your August lock to make sure you match up the various pieces of mounting hardware with your existing deadbolt, but overall installation is simple and should only take about 15 minutes. Essentially, you take off the thumbturn, and use your lock's existing screws to attach the August mounting plate and adapter to your door. To hang the August lock itself on the mounting plate, you lift up two little "wings" on each side of the lock, situate the lock on the plate, and the push the wings down to hold the lock in place. In theory this installation should be simple, and if you align everything correctly it will be. If it doesn't all slide together easiler, you'll be tempted to push the lock in hard and force the wings down if you don't get a perfect fit at first. I broke one August by turning it too hard. If it doesn't latch on to the plate easily, start over.

Once you install the lock, or likely even after you take it out of the box, you'll notice that it's big. At almost 2.25 inches thick and 3.25 inches across, it's smaller than the boxy control units that come with most of the other smart locks we've seen, but between its size and its unique shape, August gives a bulky first impression. I got used to its looks after a few days. There's a certain Duplo-inflected charm to its stubby, over-sized appearance. program car garage door opener hondaThe silver case and the line pattern etched into the finish also look good (black, red, and "champagne gold" options also available). windows and doors abingdonI also like that the metal ring around the lock functions as a mechanical turn for the deadbolt. cheap internal doors cardiff

It's crucial that any smart lock performs its basic lock/unlock functions regardless of whether it has power. August's approach does that well. You use four included AA batteries to power the August. To connect it to your phone, download the August app, turn on Bluetooth, and follow the software walkthrough. It works with iOS 7-plus-based devices from the iPhone 4S forward, and with any Android 4.4 or greater-based device that also has low-power Bluetooth. door panel curtains lowesThe only difference between the two versions is that Android lacks a handy auto-unlock feature. pre hung door specsAugust tells us it's working on adding it to Android in a future update. 1996 toyota rav4 2 door for saleDuring set up you'll create an account and manage a "Keychain" designed to handle multiple locks. 2012 4 door ford raptor for sale

You can name each lock, and if your account is dubbed the "Owner," you can manage all of the settings and distribute e-keys to anyone with a compatible smartphone or tablet. August carves out an advantage for itself with its free, unlimited e-key distribution policy. Kwikset and other smart-lock makers charge you per key once you go past a certain allotment. That approach has always felt stingy, and I'm glad to see August expose it as such.The Basic necessity of security can be attained by designing various door locks such as mechanical locks or electrical locks. These kind of door locks are designed with one or more keys, but for locking a large area various locks are needed. Generally, traditional locks are heavy and that are not strong as they can damage simply by using some tools. Electronic locks are better over mechanical locks, to resolve the security problems that are connected with the mechanical locks. In recent days every device uses digital technology. For example, identification of digital device using token, door lock system using digital technology, automatic door opening and closing, automatic door lock systems, etc.

These kind of systems is used for controlling the movement of a door without using a key. The proposed system uses an Arduino board and RFID readers The RFID reader is a wireless device used to transfer data for recognizing and tracking tags connected to objects. The tag includes electronically stored information. Some kind of tags is run by electromagnetic induction from magnetic fields formed near the reader. RFID reader includes an RF module and it acts as a both TX and RX of radio frequency signals. The transmitter of this module contains an oscillator to make the carrier frequency. A modulator to intrude data commands upon this carrier s/L and an amplifier to increase the signal enough to wake the tag. The receiver of this module includes a demodulator to extract the reverted information and also holds an amplifier to support the signal for processing. A microprocessor is used to form the control unit, which employs an OS and memory of this module filter and stores the information.

Arduino is a microcontroller board based on the Atmega family. It consist of 14 digital I/O pins. An Arduino board includes 6 analog i/ps, a USB, a reset button, an ICSP header a 16 Hz quartz crystal, and a power jack. It covers everything desired to support the microcontroller. It is simply connected to a computer with a USB cable. Interfacing of RFID with Arduino can be done by the following steps The necessity of power supply for RFID readers varies from one product to another. There are many RFID readers are available in the market with 5v, 9v and 12v. But, here a 12v RFID reader is used for an interfacing. You may confirm the RFID reader and RFID tags are frequency compatible RFID gives mainly two possible outputs, one is TTL compatible o/p and another one is RS232 compatible o/p. A TTL compatible o/p pin can be connected to an Arduino board directly. While the output pin of an RS232 compatible must be changed to TTL using an RS232 to TTL converter The automatic door lock system circuit diagram using an Arduino is shown below.

This circuit is mainly used for an interfacing of RFID reader with an Arduino. This project can be enhanced by connecting an LCD display to display the outputs. The circuit of this project uses three separate parts, namely a reader, a controller and door lock. Where a reader reads the RFID tags, a controller is used to accept the data from the RFID reader and control the o/p of the door lock and RGB LED. When the door lock is placed on a door and tested with a battery to check the installation. In many cases we need a simple circuit on the door lock, that means the automatic door stops locked when there is no flow of current. When 12 volts DC is supplied through the electromagnet in the door lock system, a plate in the door lock offers a way to permit the door to be pushed open easily. The RFID reader is placed on the outside of the door and it is detached from the controller confidentially so no one can avoid the security by breaking open the RFID reader and trying to short circuit the reader.
