Temperature Sensors
Переглядів 5512 годин тому
Temperature is a condition of a body by virtue of which heat is transmitted to or from other body. Temperature is a fundamental unit like mass, length and time. Temperature is measured in ⁰C or ⁰K or ⁰F. Three mostly used Temperature Detectors are Thermocouples Resistance Temperature Detectors (RTD) Thermistors Thermocouples are most widely used temperature detectors in industry. The working pr...
Light Sensor

A light sensor is a device that is sensitive to light and can detect light and convert it into an electrical signal. It can measure the intensity, wavelength, frequency or direction of light. A light sensor is something that a robot can use to detect the current ambient light level - i.e. how bright / dark it is. There are a range of different types of light sensors Photoresistor Photodiodes Ph...
Capacitive Sensor

Capacitive senor is used for measuring displacement, velocity, force etc. It is a passive type sensors in which equal and opposite charges are generated on the plates due to voltage applied across the plate, which is separated by dielectric material. A combination of plates which can hold an electric charge is called capacitor. The capacitor may be characterized by q, the magnitude of charge on...
Eddy Current Sensor
Переглядів 83День тому
Eddy-Current sensors are noncontact devices capable of high-resolution measurement of the position and / or change of position of any conductive target. Eddy-Current sensors are also called inductive sensors, but generally, “eddy current” refers to precision displacement instruments( or non-destructive testing probes) and “ inductive” refers to inexpensive proximity switches. High resolution an...

Potentiometer and its types
Переглядів 4414 днів тому
A potentiometer (POT) can be used to convert rotary or linear displacement into voltage. The potentiometers can be classified into following two types. Linear Potentiometer Rotary Potentiometer A potentiometer is the most common position sensor. This type of sensor is basically a fixed resistor with a movable tap that allows the amount of resistance between the tap and either end of resistor to...
Rotary Variable Differential Transformer (RVDT)
Переглядів 6121 день тому
RVDTs are used whenever precision angular motions / displacements are measured. The RVDT uses the same principle as LVDT except that it has a magnetic core. The output voltage of RVDT varies linearly with the angular motion. The shape of the core is cardioid type and is made of magnetic material. The shape is chosen to produce a linear output over specified angular movement. Figure shows the RV...

LVDTs are mostly used transducer to translate linear displacements into electrical signals. LVDT find a number of applications in both measurement and control systems. Their high resolution, high accuracy and good reliability and stability make them an ideal device for applications involving short displacement measurement. LVDT consists of one primary winding P and two secondary windings S1 and...

Happy new year madam
Happy New Year 😊
I have some questions mam
Good evening mam
❤ do more videos
Does geostationary satellites follow all three kepler’s laws?
Thanks for the video! Very helpful! If I could make a suggestion: the use of these effects on the slides more distract than help... other than that, great video!
Nice mam
Nice Explanation mam.
Thank you very much sir
Thanks 👍
🎉best in UA-cam
Super madam
Thanks sir
Thank you mam, I have to take seminar this topic ,it very easy to understand.. ❤
👍
after i execute matlab to test for yout formula, but still have different result for distance but still a nice video
% user defined data : Satellite Re = 6371e3; % Radius of Earth(km) h0 = 554e3; % altitude of satellite ex:starlink-1007 alpha = 53.1; % inclination, elevation angle (>= 10 degree) % according paper's formula d = sqrt(Re^2 * (sin(alpha)^2) + h0^2 + 2*h0*Re) - Re * sin(alpha); % use law of cosine % d = sqrt(Re^2 + (Re+h0)^2 - 2*Re*(Re+h0)*cos(alpha)); % d = sqrt(Re^2 + (Re+h0)^2 - 2*Re*(Re+h0)*cos(alpha-90)); % d = sqrt(Re^2 + (Re+h0)^2 - 2*Re*(Re+h0)*cos(90-alpha));
thanks for this vid!! really helping me learn all of these different types of systems
Where is part 2
what a poor explanation or i may say no explaination at all,is it a reading class ? You are literally reading the slide with no explaination at all,I dont understand how people like you even have 1.25k subscriber ...... It was a complete time waste watching your video
Thanks for sharing. Do you recommend any commercial integrated circuit with these capabilities?
Voice not clear
Maam is there any reference book available for bio amplifier design??
Then where is micro TESLA mam
improve ur voice quality
Easy to understand 😊
Nice explanation mam☺
voice is not clear ma'am 😢
finally got you #deva_sena
THANKS YOU
This Radio
Maam please improve audio
Thanks for your valuable suggestions. i will improve the audio quality in my further videos.
Good
Good info 👍
superrrrr flowerss
Very useful for the students who are studying Satellite communication. Neat and clear explanation mam. Thank you very much mam
Very nice and simple introduction of Satellite communication mam. Animation Pictures are so beautiful. Keep posting such useful videos mam
Nice mam
Thank you mam.
Mam tamil la explain Panna mudiyuma
I will try to explain the contents in Tamil in my future videos ma.
I´m taking advantage of the fact that this is the first comment of the video, a rare thing. I ended up on this board because of the similarity on any input adaptation to the user, beeing eq, or mechanical automation, or any drive by wire device control. Independent of the device, mechanichs or reaction we try to simplify nowadays, I think the progressive adaptability for each individual has to be coherent in any case. So my question is, is that the case?. Can reaction times be reduced regardeless of the action or reaction for a specific person?. Can the same calculations be used for a person even if it is foot pressure or audible reception?
thank you, that's what I've been looking for
So nice to see the video mam
Thank you very much sir.
wow learning with emojis nice concept. Thank you mam for your efforts!
