  PIR sensor and relay interfacing with ARDUINO  ( Automatic light by PIR sensor) PIR SENSOR(Motion Detector) :-__ Hey guys, Do you know how we  can  detect motion of human? yes, we can detect motion of human by PIR sensor. PIR sensor use for many more applications  such as automatic switching operation of outdoor lights, lift lobby, common staircases, automatic switching operation of garden lights based on the presence of a human being, for covered parking area, automatic door operating system in shopping malls, and so on What is PIR sensor? A  passive infrared sensor  ( PIR sensor ) is an electronic  sensor  that measures  infrared  (IR) light radiating from objects in its field of view. They are most often used in PIR-based  motion detectors . PIR sensors are commonly used in security alarms and automatic lighting applications . When the warm body leaves the sensing area, the reverse happens, whereby the sensor generates a n...

  Sound waves, which are all around us, are simply organized mechanical vibrations traveling through a medium, which may be a solid, a liquid, or a gas. This applies to both the everyday sounds that we hear and the ultrasound used for flaw detection. What is ULTRASONIC? Ultrasonic  vibrations of frequencies greater than the upper limit of the audible range for humans—that is, greater than about 20 kilohertz. The term  sonic  is applied to  ultrasound  waves of very high amplitudes Hey guys , some time we need to detect a measuring a object how much far from us as we have to detect enemy at Airforce RADAR or Marine RADAR and also used in industry to detect a defect in material etc. Principle of ultrasonic detector Ultrasonic sensors  emit short, high-frequency sound pulses at regular intervals . If they strike an object, then they are reflected back as echo signals to the sensor, which itself computes the distance to the target based on the time-span be...

Hey guys, here we learn about something lcd display and how to coding that display. what is LCD ? LCD stands for liquid crystal display   These are commonly used in the screen industries to replace the utilization of CRTs.   Cathode Ray Tubes   use huge power when compared with LCDs, and CRTs heavier as well as bigger. These devices are thinner as well power consumption is extremely less. The   LCD 16×2 working principle   is, it blocks the light rather than dissipate. This article discusses an overview of LCD 16X2, pin configuration and its working. LCD 16×2 Pin Diagram Pin1 (Ground/Source Pin): This is a GND pin of display, used to connect the GND terminal of the microcontroller unit or power source. Pin2 (VCC/Source Pin): This is the voltage supply pin of the display, used to connect the supply pin of the power source. Pin3 (V0/VEE/Control Pin): This pin regulates the difference of the display, used to connect a changeable POT that can supply 0 to 5V. Pin4 (R...
