Blynk Controlled Fan Regulator without Humming | Fan Regulator working explained | IoT Projects

In this video we will be studying the circuit and working of a Fan Regulator and after that we will try to make our own Fan regulator that works over Internet using Blynk IoT platform.
In the previous version of my AC dimmer, there is one problem of humming if you connect that circuit with a fan. But with this Capacitive dimming method you won't face any humming sound issue.

Hey, Techie.. I have made the same project a year before... Your circuit is really good.. A great project👍

[@Zohaib.S.H.K]

? Codes circuit diagram

[@trego9584]

Great Job-like always I love all the work you do. There is one thing that you need to add that is a box to install the relays in and some type of shielded cable for all the mains voltage. None of the higher voltage terminals or wires can be exposed

[@sparshsinghg]

Finally😭😭 I was searching this for months, I tried leading, trailing edge dimmer but they cause humming noise. Thank you so much for this video

[@techiesms]

Happy making 😇😇😇 And do share the video on Instagram (@techiesms) once you make this project

[@jssahoo3205]

I am using ac dimmer for Controling fan speed and it working perfectly, no humming sound. I made the circuit from one of your tutorials and order it from jlc PCB. Thank you for all the simple and smart ideas.

[@techiesms]

Humming sound comes when your fan is running at slow speed

[@manu8482]

Your reverse engineering process and your explanation for that is amazing. 👍😀

[@pvs6044]

I am gonna implement all you home automation in my room by doing it by my self thank you sir !!🙏

[@its.r.r]

Thank you for a well made video with crystal clear explanation. Oh by the way a very neat handwriting on the circuit diagram makes it easy to follow as well. I too am into home automation and am looking to control the speed if a fan by voice through Alexa. You wouldn't have a video on that would you?

[@yuvarajs8657]

Great work in reverse engineering a fan dimmer, but it would be simpler to use a Triac for Dimming application and the circuit would be smaller and cost efficient aswell..

[@mohamedragab1201]

Very good project thank you

[@Versa_Sajid]

Awesome idea. This video was also very informative like your other videos. One drawback is this is bulky. My sugestions, the same thing can be achieved using 2 relays also. Fix it on a custom made PCB to make it smaller.

[@techiesms]

Ya with a custom pcb this will become compact

[@debarkamondal6406]

How to do it with 2 relay?

[@Arunkumar18]

Nice one 👍 My alternate idea is to attach a cheap servo (sg90)on top of the regulator. There by you don't disturb the existing connection.

Yes

Such a ginormous fan regulator. This looks like overkill. But it can be a nice Juggad thing for learners and hobbyists. There are many other ways to get hum reduced out of these fan regulator circuit using proper methods. Anyways your explanation presentation is good! keep it up.👍👍👍

[@Crestpak1]

I need some clarification, as you say that point 3 is connected to point 1 and point 2 it means all 3 points are shorted, in that case either we select point 1, 2 or 3 path of electricity will remain same as the electricity will flow from a common node to all paths

[@CATips]

[@earthpower1230]

Super video

[@LittLe_PunK]

great project sir. i am going subscribed.....but ,is it possible if we make a fuzzy logic to control an alternating current fan?

[@madhukeshnp]

You should have used "STEP WIDGET" instead of slider. That would have made sense as the regular fan regulator has steps to control the speed.

[@yogendrajamsariya1193]

Awesome

[@delrstudio.2252]

Best!

[@deepbhavani7391]

I think you also can use some kind of transistor(bd139) , MOSFET,triac(bt136) ,etc.kind of electronic switch to avoid sound of relays and to minimise the cost also.i hope you like my idea ,thxx for show your idea to use😀.

[@drelectronics13]

He did which gives humming sound so he made this video

[@KrupalDesai]

Hey Sachin, this is great explanation and very well presented. I have been running similar setup for more than a year except with D1 mini board and ESPHome firmware - it has been a rock solid. Like you presented, I did use the existing regulator board by removing the rotary switch and soldering wires which go to relay board. I'm facing hard time finding these capacitors. Do you know from where can we buy the capacitors separately? On a side note, I also tried to design custom PCB with two big capacitors and 3 relays to make it compact but didn't order as unable to find the capacitors. I shared PCB renders to you via email last week which includes this board. Do you happen to see that?

[@blaise4083]

hi......can you please tell me which fan regulator brand was it ? ..... since the regulator i brought from store has 6 terminals for the rotary switch (my regulator at speed 3 connects to 2 separate terminals instead of connecting to pin 3 and pin 2)

[@prakharsethi4910]

Hi. I liked your attempt. Can you indicate the fan speed against each relay module? Also it would be nice if you provided a proper schematic; it is hard to see from the wiring diagram which gpio is used.

can i use a triac , instead of a relay ? (i will use optocopler and triac for switch on/ off power )

[@muhammadabrar6230]

You need to find a way to put software speed control in this order, OFF>>High(4)>>Mid(3)>>MidLow(2)>>Low(1) or there's gonna be fan coil damage or something like that.. the regulator u tore apart should also be in this order.. Or Make sure Fan is at highest speed while turning on

I have used 5 buttons to operate this Button-1 :- Off Button-2 :- D8 pin will be on D9, D10 will be off Button-3 :- D9 pin will be on D8, D10 will be off Button-4 :- D8, D9 will be on D10 will be off Button-5 :- D10 will be on D8, D9 will be off I usedCapacitors and Resistors which is in domestic dimmer to drop the Voltage. We have to use more buttons in this project. But I want to use only 3 buttons in this project. I want to use button -1 as Fan start and stop By using button When the power is off, after coming the power the last function should be stored in eeprom
