Room Visitor Counter With Relay Control: Home automation is a really neat use of technology. * Zip ties or wire ties Battery Powered Lamp That Turns on Through the Use of Magnets. In fact, the Automatic R… Luckily I've done it so you don't have to! Automatic Room Light Controller with Bidirectional Visitor Project showcase by Team Amrendra Sahni 9,307 views 4 comments 12 respects Using Arduino and WIZ750SR to control the smart building lighting system. Some time ago I devised (but never got around to build, that's my curse) a system with a pair of IR detectors several cm apart, an IR LED between them and a mirror across every doorway leading to / from a room, all of them feeding their signals to a single controller. Why did I pick the MSP430 and TI Launchpad? I could have opted for an enclosed case, but I started off simple. So without further ado, here's an explanation of what this Instructable aims to show you how to build: -->At least 1/4" long; I used 3/4" metal standoffs because that's what I had. * Low cost (about $2 for a DIP package) That is ''High Voltage''. * The coil driving voltage should be less than or equal to the unregulated voltage input to the microcontroller circuit. Since this is just plastic, you should be able to get by using any type of blade. The room visitor counter (as you might have expected...) counts how many people are currently in the room, given this room only has one means of entry. Therefore, an automatic room-light controller automatically turns on the lights when a person enters into a room, and turns off the lights when the person leaves the room. This really comes down to soldering and circuit layout skill. I just chose this microcontroller because I liked it.NOTES: When everyone exits the room, the light turns OFF. If you are feeling adventurous, it wouldn't be a bad idea to enclose this in a box for better protection and visual appeal. Share it with us! Technical stuff: A PROJECT REPORT ON AUTOMATIC ROOM LIGHT CONTROLLER WITH VISITOR COUNTER IN THE PARTIAL FULFILMENT OF THE REQUIRMENT FOR THE DEGREE 2 ABSTRACT In this project, we will see the Automatic Room Lights using Arduino and PIR Sensor, where the lights in the room will automatically turn ON … We're not talking firepoles here - I mean a doorway. By the way, I'm not affiliated with TI, and I'm not promoting products. Automating the process of turning off the lights when you leave the room is nice if you're a tad lazy like me, and also is a way of being kind to our Earth by saving energy! it would be cool to see the satistical data on which room gets the most use. We often forget to switch off lights or fans when we leave a room. The dimensional drawing can be printed in 1:1 scale, Achtung! I started this project… The detail in this instructable is on a higher level of abstraction. From there, I realized that a natural extension was to have a pair of sensors in every doorway, enabling the system to "know" how many peope are in every room (people who increment some room head count always decrement some other room's head count, if one define "outside" as another room). In this project, we will see the Automatic Room Lights using Arduino and PIR Sensor, where the lights in the room will automatically turn ON and OFF by detecting the presence of a human. After a while the other one leaves, and only then the lights go off (after a brief delay in case someone returns). We learned how to program the family in C++ and Assembly, but really only scratched the surface. We will be using the current schematic in this instructable, but the principles of hardware assembly should be a good guideline in that instructable. Today we are here with automatic room light controller project with bidirectional visitor counter by using Arduino Uno. When Any Person, Animal Or Any Object Comes In The Range of the sensor. Ppt on automatic street light control using ir sensors 1. -->We'll use 4 of these to mount the PCB* 4 nuts, sized and threaded to fit the machine screws Put 'em in all the rooms, and take out all the manual light switches! leaving the lights off when leaving a room whith zero count) Catch #2: Too many wires everywhere. * The female headers are not completely necessary; I used them because I like modularity. Warning! This automatic room controller can be implemented by using a simple microcontroller and wireless IR technologies . I cut the plexiglass from a larger piece using a tablesaw. -->These are for mounting the IR sensors -->This is cheap yet study enough to keep this all together (plus, I use plexi for everything)* 2 threadedstandoffs, metal or plastic I am using the assembly I made in this Instructable. If you have any questions about the code, direct them at the comments, or send me a message; I'm glad to help. Ooh that's actually a really good idea! In This Circuit PIR (Passive infrared ) Sensor Is used which is used as motion Detector. The order does matter; we will find out when we test it whether or not we need to switch the sensor cables. Take note that the Fritzing file does not have the completed relay section due to the way I made the schematic That would definitely be cool, yes; I'm sure you could cut a small slit in the drywall, fit in the sensors an then full in the gaps with plaster of Paris or something of the like!
