SENSOR: The sensor is a transducer type, it is used to sense or detect events or changes in physical quantities and gives a corresponding analog output. TYPES OF SENSOR: 1. IR sensor. 2. proximity sensor. 3. Temperature sensor. 4. Pressure sensor. 5. Light sensor. 6. Fires sensor.
DIY – Means Do It yourself. Make simple and Low cost LFR-Line Following Robot using AT89c51 Micro controller IC. A line follow robot is autonomous robot that follows here my robot either BLACK LINE IN WHITE BACKGROUND or WHITE LINE IN BLACK Background. The motor drive circuit
Linear Variable Differential Transformer (LVDT) is extensively used transducer in industry and so explained here in detail. LVDT CONFIGURATION Figure 1 shows this mutual inductance transducer. The primary is excited by an external AC voltage. The secondaries, both of equal turns and identical placement about the primary are so connected
The resistance R of a given material is proportional to its length L and inversely proportional to its area of cross section A. Thus R varies as L/A and = P(L/A), where p is the constant of the material known as its specific resistance.
SMD devices are usually moisture/reflow sensitive. Moisture from atmospheric humidity enters permeable packaging materials by diffusion. Assembly processed used to solder SMD packages to PCBs expose the entire package body to temperature between 160C – 260C. During solder reflow, rapid moisture expansion can result in package cracking, delamination of critical interfaces within
How to Test 7 segment display LEDs with Digital Multimeter:- STEP-1: Connect:-Digital multimeter (Testing common anode OR cathode) DMM + probe to Common Pin ( To 5 pins in the centre see animation picture)
The DC motors are used in many applications like process control and automation in industry, Robotics, printers, and scanners also. Speed control is an important factor in these applications. Speed of DC motor depends upon the average DC voltage applied across its armature. If the polarity of
