Motion Sensor Bed-lights (NO PROGRAMMING)

[@judeboxlie]

This guy explained so well that I think I would be able to do it by myself ! Thank you Grensom

[@midlivad]

Great clip, one of the best I have seen so far. Clear and easy to understand instruction + super clear content delivery.

[@tejasmarathe6911]

Successfully using this for months now. Just had to take out those resistors and then the circuit started working just fine. Thank you.

[@insanthereal3975]

Hey bro mine circuit output is coming around 7-8 v...bt led strip need 12v to lit

[@R1chardH]

Ive put this off too long mostly because I don't have a clue and want to do the wardrobes as well but will need to wire additional pir sensors in for that, but this video has inspired me again

[@JoeCauley]

any way I could buy this from you? This is EXACTLY what I need!!

[@DavidHansen92]

Dope.. will probably be giving this a go myself. Lot of functionality for a small price.

[@youssefmosalam4638]

Where is the battery? Or where is the supply source ?

[@officialbodega1535]

you can see it in the prototype @1:47 he refers to the battery as VCC (Collector supply voltage) @1:29

[@preds.bundalo5408]

Very cool project. Thanks for sharing.

[@causewhynot4084]

Love it so muchhh hahah!! Idk if it’s possible(easily), but you should try one where it only lights up where you are walking, it kinda tracks you!

[@mrgeerders]

I'm gonna make a few of these for my new RV since everyone leaves the pantry light on and shuts the door! Very helpful!.

I'm going to build so much cool stuff this winter.

[@RajatKumar-tf1ow]

I tried those in my minors' final years... You actualised them. You are reading my mind lol. Great job man. Looking forward for more videos .(I loved the way you explain those circuitry, way better than my professors 😊) Love from India.🤗

[@gokukn2336]

hi bro.. what is the power source he or you used for this project.. AAA batteries x 2 or Ac power source..? please reply.. Does it work on AA or AAA batteries..?

[@ShikshaThisSide]

Oh waoooo I the way u explain is awesome nd your projects r absolutely lit. Keep it up do more projects coz I wanna learn more and more from your videos.💕

What is wired into the breadboard? and is it mostly or testing the connections?

[@janvavra6515]

Hi! I want to build it too and I have an issue. Can I use mosfet 60V 50A ??

[@AhmedHaggag]

Dose it trigger when you move around the room?

[@SoloBronze]

Hi, Just made this with 3 x AAA batteries and without the resistors. It works great with a short LED strip, but as soon as I connect a longer strip it just keeps turning on and off at will. Is this due to the lack of resistors or the power supply, or both?

[@andychesaru632]

Something you did not mention,for this to work you will need a Logic Level MOSFET,that can activate at 5v. Most of the MOSFETs operate at 10 V,therefore a higher resistance appears. Other than that,great video! Love it.

[@Grensom]

Yes you are right, I did not really mention anything about that in this video as it is important to know that in order to get this project to work. I have the link in my description linked to a logic level MOSFET, so hopefully people will look there for the part if they are unfamiliar with MOSFETs.

[@Rob_III]

Will an IRF640 Power MOSFET 200V 18A work? Would I have to make adjustments to the schematic? www.infineon.com/dgdl/irf640n.pdf?fileId=5546d462533600a4015355e7b76c19eb

[@JohnPender]

I need to make a modified version of this for my kitchen pantry and all of my smaller closets.

[@noahkingjohnson1234]

Question 3:30 what was that piece you cut up? And 3:41 what is that piece and where did you put it? And I still don’t understand where is the power supply? So what do you use for the power?

[@Grensom]

3:30 that is a “perf board” and at 3:41 is my 12VDC to power the circuit. I ended up connecting the [+] and [-] to a barrel jack and connected a 12VDC Wall Power Adapter. I wired everything together based on the diagram in the video at 2:31

[@noahkingjohnson1234]

@@Grensom i can’t see where you put the 3:41 piece, can’t see it anywhere on the module?

@Grensom You have mentioned 1k ohm resistor here in this video but on the written instructions on hackster you have mentioned 10k ohm resistor. Which one will work good 1k ohm or 10k ohm, also I'm buying an led 12volts with 1amp is 1amp led sufficient, will it be bright enough and will it work with this circuit?

Which battery is used in this....???

[@nitin7193]

It works!! Thanks Grensom. 1. I'm thinking of adding LDR to this, any idea which one to use? 2. thinking of adding a blocking diode so I could connect 2 sensors on either side of the bed. any suggestions of which one to use? (odered all parts from your links, so entire circuit is identical). Thanks in advance

[@leon9357]

Can I use any N- channel MOSFET?

[@s9438679525]

Hi Grensom, Is there any alternative for Mosfet as I am not able to find the specified one. Is it okay if I use a 50A 60V ?Please reply

[@Grensom]

Hi, you just have to make sure you use Logic Level N-channel Mosfets. You can use these ones: www.amazon.com/WeiMeet-RFP30N06LE-N-Channel-Mosfet-Arduino/dp/B07CTF1JVD/ref=sr_1_3?ie=UTF8&qid=1550066124&sr=8-3&keywords=logic+level+n-channel+mosfets

[@ethicalhacker1]

I have the same question were you able to use the 50a 60v instead?

[@wflores9711]

What kind of N-Channel MOSFET are you using?

[@ethicalhacker1]

Does this turn off automatically after the person has left from in front of the sensor?

Grenson, is that a jumper you have connected to the blue LED? I'm to build on of this for my new bed.

[@LalGebi]

Awesome Bro.. can you design a LED circuit which turns on when motion detected and only on the night. It remains on until person is there in front of sensor range and shuts off after the specific amount of time when the person left

[@Grensom]

If you look where I explain the motion sensor circuitry there is a solder through-hole for a photo-resistor for doing just that.

[@snowchild5029]

@@Grensom but with photoresister, won't it be invalid when other house light bulbs are in, so I think some time sensor might be needed, something like that. Gr8 vid though

Hey Grensom, trying to make these for my wedding corn hole games. I’m really confused on the part where you soldered it to the perf board. Any chase you could describe that a little more for me or any way I can pay you to make me a few of these?

[@Grensom]

Hi, basically the perfboard was just me putting the circuit from 2:30 onto a consolidated board. Perf board is the easiest way to do this. As for using this for cornhole, you may want to use a different sensor for detecting a cornhole bag. Passive motion sensors pick up infrared signals put off by body heat, so inanimate objects are not well detected.

[@minabobina420]

Will this have enough range to be activated by the person sleeping on the other side of the bed too?

[@ethicalhacker1]

These pir sensors detect upto 7 metres and not more than that, so maybe you would have to add another sensor at the other end of the bed...

[@xXxDaRkOlImxXx]

Can I make it to turn on with google assistant too?

What are the wires you are using

[@Grensom]

26 Gauge Wires - solid strand

[@Mevangeli]

How long will AA power the LED Strip?

[@Grensom]

I guess it really depends on how many lights you are using, if you are using maybe 20 LEDs, at 20mA per LED, that is a total of 400mA. Now a normal AA battery has 2.8 Ampere Hours so -- 2.8/0.4 = 7 hours. So it looks like 7 hours continuously with AA batteries. I would suggest maybe using a 12V power supply instead though - less hassle. That's what I ended up doing.

[@DavidHansen92]

How would you incorporate a 12v power supply versus the AA batteries, assuming you have little to know experience in electrical wiring..asking for a friend lol XD Does the wiring schematic change or is it as easy as a simple swap?

[@Grensom]

Its a simple swap. If you use the Power Supply I did: www.amazon.com/gp/product/B019Q3U72M/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1 It comes with a connector so all you need to do is wire in the red wire to the (+) screw terminal and the black wire into the (-) screw terminal and you are all set to go!

[@DavidHansen92]

Sweet figured it'd be fairly simple..legend!

[@DavidHansen92]

last question.. how hard is it to figure out that perf board portion of the build. Glazed over that fairly quickly and I imagine it's also fairly simple. Want to use this as an entry level project to get into this kind of stuff. Anything weird with how those work or how you have to hook all the components up to it. Appreciate the feedback.

[@saniabearsky]

Hey Grensom! Was trying this build on my own, with some adjustments: - 12v, 8.3a power source - same PIR module and 10k om resistor - P30NF10 mosfet n-channel transistor - datasheetspdf.com/pdf-file/712795/STMicroelectronics/P30NF10/1 - SMD 5050 RGB led strip with control box and RC (12v, 14.4W) Though PIR and transistor are working ok, I ended up having significant voltage drop (down to ~5v) at the control box terminals. Any ideas, where I messed up? Thanks!

[@heidiwelu3690]
