A 330-ohm resistor is connected in series with a 2.5v LED. The PCB design given with this article makes the assembly much simpler. As PCB contain 230V AC main lines care must be taken while assembling the circuit.
Upon scanning the right tag and entering right pass, it will open door and send confirmation message otherwise it will send alert message.

You can connect and access it from your iPhone, allowing you to watch what’s happening within your compound while you are away. Whenever you leave your house and someone opens the door, the card will be pulled out from the cloth clip due to the magnetic attraction and you will receive a call on your phone. Find a home automation company or home cinema installer on Houzz. Narrow your search in the Professionals section of the website to Frankfurt, Hesse, Germany home automation companies and home cinema specialists. You can also look through Frankfurt, Hesse, Germany photos by style to find a media or technology installation you like, then contact the professional who designed it.
Try to adjust the line of sight LEDs so that the buzzer gets Off. Sensorvalue1 is a user defined function and this function is called every 1 second. We are sorry, we don’t sell kits or assembled boards of this project. Adjust R11 preset to control the “Day” and “Night” mode detection. You should discharge the CRT monitor first to avoid the risk of electrocution. If you have a pacemaker or a heart condition, this project is unsafe for you.

Both the Power Supplies are exactly the same and can be powered up using a single 12v adaptor. This system uses a Microchip’s PIC16F877A as a main controller, LM339 as sensor interface, UM3561 as a tone generator and μPC2002 as a speaker driver . LM7805, LM7812 and LM317 voltage regulators are used to obtain +5V, +12V and +3V respectively. Although you may not be able to turn your home into a burglar-proof fortress, or even want to, you can make it difficult for anyone with ill intentions to access your space. And you don’t need a massive budget for a high-end security system.
Remember that CRT monitor that’s gathering dust in your attic? Just because it’s years behind technology doesn’t make it completely useless. Check out this guide on Instructables to transform a CRT monitor into a personal electric fence. Here are more creative ideas to upcycle old TVs. You don't have to spend a fortune to keep your home secure. Check out these easy-to-make DIY home security projects.
IoT Security System Project Description:
As you can see all the pins are clearly labeled with OUT, GND, and VCC. The Red wire which is the VCC wire will be connected with the 3.3v pin of the Nodemcu module. So if your sensor has a logic high/low you may discard the input OPAMP circuit and connect them directly to microcontroller assuming that their output is 5V.
Yes, the circuit instructions were built with the intention that beginners could build it. Check whether the negative terminal of the buzzer and the green wire going to the NO terminal of the relay are connected in the same column. In the void setup function I activated the serial communication.
The sensor detect any motion in its permissible range and triggers the alarm. Make an alarm clock that will only stop once the light is on and the button is pressed using an Arduino Nano. You can attach it anywhere and will it will inform when someone tries to steal something. The positive terminal of the photo-diode in the receiver circuit must be connected to ground. This is the same function I have been using in all of my IoT based projects.
An Alexa enabled door lock with face recognition and remote control. Secure your house by implementing this handy automatic door management system. As the TO didn't tell us which month he will arrive it could be possible that the borders are still closed and no immigration possible. From the arrivals hall follow the signs to the long-distance trains/Fernbahnhof. You need to take the luggage off the trolley before you take the escalators down to the platform. Construct this simple door bell chime and have fun.
Electronics Project Design references and tips for high school students, teachers, colleges and university students, electronics hobbyist and electronics designers. Test your hardware and software skills against the best designers from the rest of the world. Once the contact is momentarily closed, the first timer which is configured as a monostable output will output a high pulse with a duration up to a maximum of 220 seconds. You can also purchase a device like the Defender Security Reinforcement Lock to give door kickers a hard time. Attach contact sensors to your home’s windows and you’ll know right away if someone’s trying to get in. If you were to check your home’s windows right now, chances are you’d find some were carelessly left unlocked or have inoperable locks.
This could be the simplest YET brilliant project / idea. The plastic will retain its shape when cooled down. Carefully peel off the button sticker from the keypad.
Check out the detailed guide on Instructables to hack this project. If your kids love this one, it is time to introduce them to more DIY projects to spark their creativity. If you love taking strolls around your yard just to see how everything is but never get the time to do it, you’ll love this Arduino-controlled 4-wheel drive security robot. It features a pair of cameras, a controller with more than 400 yards range, and a reflector to illuminate the surrounding area.
Here are ten basic DIY projects to significantly improve your home’s security. In this Instructable, i decided to use an old mobile phone to make a simple Home Security Alarm which is very useful and easy to make DIY gadget. This is one of a cool things that can be done with old cell phones. Any working phone with keypad that has speed dialing feature can be used to make this Security Alarm System. In this project, you will build transmitter and receiver circuits using an IR LED and a photo-diode. The circuit is based on obstacle detection when a person or thing comes in between the transmitter and receiver.

This control system consist with the menu driven configuration options, self tests, system report generators, etc. This system also contain 5W (with 4Ω speaker) audio alarm with three selectable tone configurations, which include Police siren, Fire engine siren and Ambulance siren. Do you want to up your home’s security but can’t afford the high price tag on CCTV cameras? This security camera lamp build on Instructables is just what you need to scare off intruders and light up your home’s space. You can opt to purchase a dummy camera or DIY your own using old cans to hack this project. The process of making a mouse security alarm is pretty straightforward, as shown in this Instructables guide.
Your insurance company may discount your homeowner’s premium by up to 20% when you install a monitored home security system. Plant thorny bushes, such as holly, under windows to make your home even less appealing to burglars. No home is burglar proof, but tackling a few of these weekend projects may go a long way toward making your home less vulnerable to a break-in.
