By embedding iot with the fingerprint sensor we can elevate the fingerprint based security system project to the next level.
Diy door lock sensor.
Some locks are even connected to the cloud and allows the user to open close it remotely and share the access to the door with other.
This door lock can be used to operate an electric strike or an electromagnetic door lock.
Smart locks are now widely available and allow users to open close a door by the press of a button on their smartphone.
You ll need a vice a hammer and a metal saw but the whole process only takes a few minutes.
This delay can be adjusted.
So in this project tutorial we are going to build and iot based biometric security system using the gt5111c3 fingerprint sensor nodemcu and solenoid lock.
I wish insteon would give us a tiny wireless diy module like arduino to allow us to build our own input output devices for an insteon network that are more compact and modular than the iolinc until then we ve got to make due with what we ve got.
A small electromagnetic strike unlocks the door.
Recently the hidden door sensor was released and we re getting closer to that dream with the miniaturization of our sensing devices.
When the hall sensor switch detects a strong south pole magnetic field in its vicinity the remaining circuit is switched on for about 10 seconds.
Fingerprint scanner sensors are used at many places like industries offices schools colleges and hotels.
The legs these are the parts that attach to the door.
When the right sequence of triggers is applied via pushbuttons the electromagnetic door lock becomes operational.
It s the perfect method to quickly modify a door and make it more difficult for intruders to come in.
Diy arduino door sensor.
When the right sequence of triggers is applied via pushbuttons the.
A small electromagnetic strike unlocks the door.
Here you have a link to thingiverse in case you want to get it printed.
Our automatic door uses an ir sensor to sense a presence and opens and closes with the help of a servo motor.
The diy automatic door opening and closing system is a simple version of the automatic door that shopping complexes and lifts have.
You ll find all the components you need to make your own diy automatic door opening and closing system in the evive starter kit.
There is space to put the reed switch inside of the enclosure or pass the cables through a hole.
We will thread the sensor s wires through here.
When the hall sensor switch detects a strong south pole magnetic field in its vicinity the remaining circuit is switched on for about 10 seconds.
Remote controlled door lock using a fingerprint sensor adafruit io by adafruit industries.
Having nice enclosures is part of the beautification process so i have designed an enclosure that you can use to put your sensor in.
The circuit of sensor based door lock is shown in fig.
Also don t forget to get pictoblox cause we ll be writing the code in it.
This door lock can be used to operate an electric strike or an electromagnetic door lock.
The code for arduino.
You may not want to cut these yet the length depends on the design of your door lock the length of the shaft on your motor and the final design of the lock turning clamp in the next step.
