IOT PCB - ESP32 & Relay - Control Anything From Anywhere

⚠️WARNING: I've made a mistake with copper clearance. Don't worry, the PCB you will download is already fix but in the video is not. Check the website page to see all about it and how I've fixed it.

🔥A simple PCB for IoT control that I've named NOOBIX. Get or send data from an online database and control the SSR relay for 220V AC. Control anything from anywhere in the world with a mobile website.

I am strongly suggesting removing the gerber files and fix them immediately. Because the clearance between 230V AC and GND of the board is very small, potentially lethal for the people who only make this PCB. This PCB can kill someone.

[aardwolf]

Echoing others concerns, I'd actually take this down and use it as a learning opportunity, destroying all of those PCBs if possible (please), "creepage" "clearance" and "safety" are the terms you are looking for. You also need to consider distances between component legs on the PSU that may be at hazardous voltages and your PCB.

[arminth]

High voltage of the output is very close to the low voltage ESP-stuff. No isolation gap. This could be dangerous.

I know all the countless advantages you might point about a ssr but with a simple relay you can do 3 ways with the room lamp, and in case of failure of device you can still control via the switch on the wall.

Thanks! Do you think this could be done with an immersion heater in hot water storage tank. I have a hot water tank that has a sink and bath switch. I'd love to be able to switch on the element for each when I want remotely, and hopefully put it through home assistant.

clearance between 230V AC and GND is horrible

[AugurIliKur]

Please head the warnings to not use this circuit as designed. It will kill people long term. AC is not like DC. The AC current conducts along the surface of wires. That makes it very, very, very easy for a slightly humid room to bridge those tiny gaps you have. You have no EMF protection. So a circuit with inductive loads will throw thousands of volts into your board crawling all over the surface of the PCB looking for things that are ground attached like humans.

Great work as always. But i want to suggest you two things with your design to make it safer. First add milled air gap between 230V line and logic lines (12V, 5V, 3.3V). 1 mm could be enough. Second suggestion ist to add a fuse between output of relay and the load. It could be an SMD fuse soldered on PCB. If relay handle 5 amps try 6 or 7 amp fuse. This could prevent explosion in case of short at the output. Thank you for your work!

Good job as always. I recently made a similar project to control traffic lights. I used 3 SSR's and a Hi-Link 5V supply instead of those "exposed" step down boards like the one in your video. It was no more difficult making 3 channels than 1. I also put test buttons on each channel on the board so you can turn on the SSR without using the microcontroller.

[jenbob]

you can try home assistant to control the boards. i am using home assistant to control my esp32 and more smarthome stuff.

[the-matrix-has-you]

However for this Project ESP32 is a bit overkill ESP12F would function just as same if you just need a binary switch. But good Project I used same Hi-link 5V Power supply for my own switch as well but my switch is. A Wemos d1 mini shield

[carloscontreras]

Hello, I have a problem with a circuit that you uploaded to your channel, it would be great if you could answer me.

[nubletten]

This is awesome. Is there any reason you do not use the raspberry chip instead?

[ulfholt]

Nice project. What power supply are you using?

[ranganatennakoon]

The best ! Great explanation always ! one of the best froum ! thanks

[ork]

when are you ganna post another video about the diy 3d resin printer

[gauravraj]

idk what's going on
just now i was searching for some esp boards to buy

[mibrahim]

Beautiful as usual ...
can you make one with SMPS design instead of the transformer ?
can you make one with websocket control instead of On/Off ?

Please make part 2 on your last transmitter remote for drone
