Hey Ludic, lovely and easy to learn as always. Thank You. I need your help with resistor selection, I want to connect a few resistor in parallel (3-4) to a 5v phone charger adapter, so that the resistors should produce heat, but should not burn. What resistor value should i go for (ohm&watt)? And number of resistors connected in parallel?
@@ludicscience wow! Reply in 7 mins... TH-cam took 1 hour to throw reply notification.. Sure, I'll arrange resistors and try it, will definitely reach out if further help is required. Thanks a lot again
Do you have Professional circuit diagram of proximity sensor interfaced with microcontroller using optocoupler ? 1. Microcontroller work on 5Volt and sensor voltage range is 6-36V. 2. Which is the best applied voltage for sensor? 3. do object detection range depend upon applied voltage ? 4. This proximity sensor is inductive SENSOR , so do we need any DIODE in reverse direction between BLACK and BROWN wire ? Its for safety of optocoupler or microcontroller or the transistor you used in explanation ? 5. For safe operation , can we use a transistor to interface at input or output of PC817 ? like you used
@@ludicscience That's what I also thought.. A pulse motor. But you should also make video on pulse motor cum charger working only on single battery. I'm dying to see such video from you
Hi I am using this proximity sensor as a wheel speed sensor in conjunction with a 12 tooth trigger wheel about 120 cm diameter Any idea what max speed ( rpm ) or Herts rate it will be able to deal with ? Thanks
So the aluminum has a negative inductance at 16 and iron has a positive at 19 from 18. I assume it works for water? Do all metals have a different measurement? if so then do they sell a element/metal "Type" detector? if you had a iron core at the center would it detect further away? I think this might have potential for other things. wih more power and a bigger coil you might be able to detect non metalit objects? Imagin using this for gold mining or seperating scrap automaticaly due to better sensors.
@@crawfish069 can yours detect the difference from silver platinum lead titanium etc? If so then metal detectors would benefit from that or to separate recycling automated. Or things that test for fake gold.
Can the sensor be exposed to a small neodymium magnet without damaging it. If so will the sensor react any different long term as an after effect of the exposure to a magnet. If magnets are not an issue is the sensors range in distance the same if exposed to a magnetized object vs a non-magnetized objuect... Just wondering how it plays with magnets...
thank you very much for this video please how to use inductive sensor signal with arduino on arduino analog input does not exceed 5v but sensor emits 12v merc
Sir, please provide detail wiring diagram of the entire connection please. I want to build one for my son's project. The power supply wiring to the coil, sensor, resistor, transistor in detail. Appreciate your help.
I've seen students use this kind of sensor in trash can crushing projects. For example, to count how many cans have been crushed. or separate the trash if it is not metal. And you can use it to detect Pneumatic or hydraulic cylinder pushing in and out. This sensor has a lot of use.
So it only detects metal objects? How about plastic, hands,etc? I need it to detect all surfaces (metal, plastic, hands, etc) except water. Can this sensor do that? Thanks
But would it actually matter? I mean the transistor used here can tolerate the current levels given by the sensor, right? From what I know the resistor is only used to limit the base current so as to not fry it? I am in no way an expert here, as I have just started with electronics 6-7 months ago so please take what I say with a grain of salt
@@AV-81 the transistor is inside between base and emitter a PN junction, a diode over wich will drop only and always 0,6volt. So without resistor there will be a unlimited current, only limited by the max the supply cán send in that base. Only with a very, very fat transistor(maybe a 2N3055 or so will not directly fry by 300mA going into its base) ór if its base gets his current from a high enough impendance currentsource, only then things will nót fry, but an electronic circuit that "works" that way is drawing a lot of unnescessairy current only tot heat some components. So yes, it matters. A baseresistor is almost always very nescessairy.
@@AV-81 If the transistor doesn't break, than the sensor will, because its output is overloaded. You *always* need current limiting unless a datasheet says otherwise. "300mA max" in a datasheet doesn't mean the sensor limits the output to 300mA, it means the sensor will be destroyed if you draw more than that. You have to make sure you don't do that.
@@ludicscience sir I inspired your videos. Towards science experiment. Sir I am from India. Can you tell which country you belong. Also I like all video. I am not your subscriber but you are a teacher to teach as a practice knowledge. Doing experiment and makes a video.
Thank you for this great video. This helped me test the sensor on my forklift. It is used for steering position.
thanks bro. for the all videos you shared
Thank you for the explanation had the last part of the video It was really great.
You are a life saver, sir.
thank you very much for sharing the code with circuit
what is the best voltage to use for a sensor that is rated 6 to 36v
Thanks so much for your help
It's kind of you
Gold leaf electroscope can be changed by a battery or capacitor? If possible please provide a demonstration.

Hi, what is the difference with Hall effect sensor ?
Merci beaucoup !
can we give it power supply of 9v 5amp...or ampere should be less then 300mA??
A very interesting device. Thoroughly surprised I never heard of it. Might need one now! haha

my sesor is always on and when it detect a metal it goes low is it possible to make it reversed like only voltage when there is a metal ?

Hobby metal detectors already distinguish between metals. I have one myself. I can set it to ignore iron for example.

You need a capacitive sensor for that
You forgot a resistor tot limit the basecurrent in the npn transistor. You could use anything from 1k tot 10k but never 0ohm!
