Human Detector

              Surveillance is an most important aspect in all over the places. Say (Banks, Jewelry shops, etc..). Now a days even a small hotels and bakery were using surveillance system to protect their properties.

             There are two types of surveillance system were available. They are,

  • Passive surveillance system
  • Active surveillance system
            Now our goal is to built a passive surveillance system which will detect the human trace when the system is fired. The materials required for this purpose are..

Hardware required...

Software required..

About Hardware..

         Controller board.


                Arduino is the one of the most leading controller board platform which provides the Learning environment for the Electronics Hobbyists and the students. There are lots of versions of Arduino board are available. But the common and the most Economical board is Arduino UNO r3.

                      It also provide a Integrated Development Environment to develop our own code and implement it.

Pyroelectric Infrared Sensor

                  PIR sensors allow you to sense motion, almost always used to detect whether a human has moved in or out of the sensors range. They are small, inexpensive, low-power, easy to use and don't wear out.

                          For that reason they are commonly found in appliances and gadgets used in homes or businesses. They are often referred to as PIR, "Passive Infrared", "Pyroelectric", or "IR motion" sensor.

                      Since its around 100 INR any people can afford it. And it could be implemented any where the user wanted.

PIR Sensor

Servo motor

             There are two types of Servo motors are naturally available. AC servo motor and DC Servo motor. For all electronic and embedded applications DC servo motor is used. Because the AC cannot be stored in the batteries.

                  A servo motor is as similar as normal DC motor but it additionally contains a feedback element and the electronics circuit. Feedback element sense the position of the shaft and it allows to move in particular manner.

                The PWM waves are implemented to drive the servo motor. It contains 3 Pins. Vcc, GND and Pulse. Its normally works on (5-12)V.


Micro Servo


LC Display

            Liquid Crystal Display is the most commonly used in Electronics projects. Because it have a characteristic to print all possible characters including numerical digits and the special characters too.

                Additionally it can't require any breakout board or drive. Its all embedded into it. So its easy to use. Here I have used 16x2 LC Display module.

LCD Module


Light Emitting Diode

                The most common and the growing up electronic component of the 21st Century is LED. When you turn around you can see a LED. It have a unique character, that its capable of working on both AC and DC.

                     Its cheap, Light weight, portable and capable of easily replaceable. So it came into picture now. And its a good indicator. Here we used LED for the Indication purpose.


Blue LED


Hookups and Protoboards

              They are normally a prototype building components which are used for the interconnection of the External Peripherals.


Hookups & Protoboard

 Let's move to Construction

                     With the help of the double sided tape just stick your servo and the PIR together as shown below. Make sure that the shaft of the motor rotates without any external disturbances.


Stuck together

        After done it. Do the circuit connections as shown in the following fig. Connect the circuit carefully to avoid the detection Errors.


Schematic

   After connecting the circuit. Your prototype will be like as shown. I hope so..


Complete prototype


   Now its time to Rock and Roll.. Just a single little work is have to done. Open your Arduino IDE and copy paste the code there..  After done it. Directly upload to it to your board.

Arduino IDE


  Take a look @ this.. Its pretty good.


Working Prototype.

                       In this moment I want to thank you my friend (Bulky)  who motivated to do this kind of work. And most importantly I have to show my special thank to my dear friend (Singer) who provided the Camera. Hope you people enjoyed.

Click & Enjoy

Thank you for your Time

Don't forget to raise you Thumb's up

A2XWY; A2XFY Cables meaning; XLPE cables advantages over PVC cables

Technical Specification of Aluminum Cables in terms of codes So many times you have seen coding while specifying cables technical such as A2XWY now what does this means. Now there is nomenclature for the same which is used while describing the same. Where A -  Aluminium 2X- XLPE Insulation W – Steel round wire armour F- Steel Strip Armour WW- Double Steel round Armour FF- Double Steel Strip Armour Y- PVC outer Sheath Wa- Non Magnetic round wire Armour Fa- Non Magnetic Strip Armour AW- Aluminum Wire Armour Now As per A2XWY – This describes that it is Aluminum cable, XLPE insulated, With Steel round wire armour and having PVC outer Sheath. This coding is as per IS 7098(Part1):1988. You have also seen that there is coding for copper so there is no coding required in case of copper cables. XLPE cables advantages over PVC cables/ Thermoplastic cables:- 1.       XLPE cables have higher Power rating about 1.2 times PVC cables 2.       XLP...

Digital Multimeter working principle; DMM working

Image
Digital multimeters are most widely used in every industry as it used for measurement of Voltage, Current, Resistance, Capacitance and various other parameters. DMMs have been available for very several years. Yet it is still challenging to locate advice about how a digital multimeter works. The operation of a digital multimeter is comparatively uncomplicated, although there are obviously differences in how digital mulimeters work if they're from different makers.Despite this, there are several similarities and some general principles of how digital multimeters work. Fundamentals of how a DMM functions The key process occurring within a digital multimeter for any measurement is that of voltage measurement. All other measurements are derived from this basic measurement. So the best technique for understanding how a digital multimeter functions is in understanding this procedure. There are many kinds to digital converter, ADC. Nonetheless the one that is most widely used DMMs in di...

Wireless voltmeter using Arduino and RF 433MHz receiver and transmitter

Image
In this project i showed you how to make a wireless voltmeter using arduino and RF 433MHz receiver and transmitter. You can use this code and concept for many other projects, any project which used sensor with analog voltage output to sense temperature, gas leakage or light , etc. For example you can put a LM35 temperature sensor rather than potantiometer, you just have to putting its formula which convert LM35 output pin voltage to exact temperature. You also can make a wireless AC or DC power meter by doing some change in code and hardware (using hall effect current sensor and single phase voltage sensor). This type of RF module has distance range up to 200 meters according to datasheet but when i bought this RF module from Aliexpress its distance rang was very low, but i set its adjustable RF coil very carefully and i get very higher distance rang.(Don't play with RF coil if your module works good), You also have to use a 6 inch antenna to increase distance range to max as possi...
