- In this video I show how to build devices which do not use any energy during "deep sleep" and so can be used for a long time. The only prerequisite: A mechanical activation through a button or a magnet.

This was an interesting concept. The ESP8266 really got me interested in programmable microcontrollers again. Having such easy wifi connectivity is awesome.
+Perspectologist You are right. It enables a whole new world of possibilities. Thats why I use it quite often
Brilliant idea to deploy mosfet/relay instead of deepsleep. Wonderful. Thank you so much!
You are welcome!
Can’t stop myself watching your channel this morning - it gives so much ideas! Thanks a lot for this.
You are welcome!
Thanks for all your videos, Andreas! They've been very helpful to help me understand what can be done with ESP8266 and Arduino in general.
You are welcome!
Hey Andreas, great job. Thank you for putting so much effort in making these videos!
You're welcome. Comments like yours help in continue the effort!
I really enjoy watching your channel. I think it has something to do with the way you explain things. Please keep the videos coming, as long as you enjoy making them. Cheers!
Thanks for your nice words. They help in going on the route
Thank you for your detailed and clear explanations. Your topics always seem to be interesting and relevant. Well done sir.
Thanks for your support!
this will help a lot of people. I really enjoy your low power techniques videos
I hope so. This is now the minimum power consumption, i think...
Perfect for an alarm for door left open on the old refrigerator in my garage. Thanks, and Happy Sechseläuten!
Cool idea! I live in Basel and we have to work during Zurich's Sechseläuten :-(
I live in the Puget Sound area of the US, and saw the holiday celebrated on a public television program. I will visit Switzerland someday if I can.
Drop me a note if you do so...
Excellent and informative channel. Always look forward to and enjoy each video. Thank you!
That is exactly as intended. Glad to read that!
This is one of my favorite youtube channels, although I'm a Spanish, I like your accent. Thanks you so much for you videos. I'm so glad to recommend your channel.
The newer videos have Spanish subtitles, if this helps.
@@AndreasSpiess no problem, I'm learning English and I understand you :) , the most at least. Anyway thank you so much for subtitles.
Hi Andreas, I love this channel! Thanks for all you do. ☺
+BEdmonson85 You are welcome!
Keep up the great videos. You've taught me so much as I venture into IOT.
Thanks!
Thanks for all the great videos. I learn lots and get inspired for new projects.
+Martin Milner Thanks for your support!
Andreas, your stuff is always good. Thank you.
Thank you. I appreciate that!
We have a side gate at our house that the kids are forever leaving open, for ages I've wanted to fit some kind of sensor to warn us when it's been left open, but without power I was stuck how to solve it. With the idea in this video to use a relay to let the processor control when it switches off is just what I need, Thanks Andreas.
You are welcome!
hello from Sydney. keep bringing the small projects in the esp8266. Ive only just stumble soon the esp8266 after watching the new wifi jammers using this board. then after a quick TH-cam search on the nodemcu I found your channel a diamond in the rough, great content. it's a pitty the smaller new channels don't get more exposure to new veiwers. awesome work :)
Thanks for your feedback. You can help the channel if you like the videos and write comments. That seems to help...
Will do, thanks for reply ;)
This is my comment to help your channel. Keep doing such a good stuff. Greetings from Poland!
+cbm80amiga Thanks for your support. If I remember right, you are one of my early subscribers.
Right!
Still have a old Amiga.
Im doing my Part!
I always learn something new when watching your videos. Nice idea about the long battery life. I need to look into IFTTT as I have not used this before. Hope the Pizza was nice.
Best wishes
Arthur
+Arthur Yarnell IFTTT is quite primitive. But they have a critical mass. And this extremely important in the internet.
Thank you so much Andreas for all these videos, your research and advice is so helpful. Its such a good idea to use a mechanical switch to keep the current consumption down. Hope one day we are able to crack the esp8266 ssl problem
+Chris Sheppard Actually it seems easier than I thought. I will show it in a later video
Thank you, I'm looking forward to it!
Greetings from Las Vegas Nevada. Thanks for excellent tutorials.

How did I not think of this? It's a brilliant method.
Thanks! We have a saying here: Somebody is always getting up earlier in the morning ;-)
Great idea Mr. Spiess
Thank you!
What a wonderful solution, thanks for the well thought out videos and explanations.
Thank you for your nice words!
I like your methods Herr Spiess. Enjoyed the video.
Thank you!
I've had an ESP8266 in my postal mailbox for sometime. It uses the same concept. When the mailman opens the box, it powers up the ESP8266 and keeps the power on until done sending a message. I've enjoyed your videos and they have inspired me to do more projects.
I have the same "mailbox" problem, but mine must be worse: The distance to my mailbox is too big for my WiFi net.So, I not only do not get a notification, I also have to walk far ;-)
This is, why I will try to use LoRa for this purpose. It should be able to go so far.
I had to use a homemade external antenna since the box is metal. It pokes out the bottom and is not very visible. I also had to put it into a styrofoam box to average out the temperature. It's too hot on summer Texas days for the processor.
The temperature part is not so important here. But I think, I also have to use the external antenna concept.
It is so small. Have you thought about fixing the processor to the underside of the mailbox so you only have to deal with ambient air temperature and not the temp in your solar oven...I mean mailbox?
Inspired! Been concerned with the irregularity of the mail service and this is the perfect idea! Also, allows me to do some statistics :)
Thank you for doing unusual things with the 8266. There are thousands of videos of people doing all the same thing. Good job doing something different.
Thank you for your feedback. Adding the same does not create value, only work ;-)

Thanks for your support!
Watched many of your videos and learned alot! Big thanks and keep making these videos! :)
You are welcome!
Wow 😲 loved the concept and execution
Execution was a little "breadbordy". But I did not (yet) have the time to make a nice box.
Brilliant, elegant simplicity. I have a sensor gizmo that uses an ESP8266 to take readings every 30 minutes. I use deep sleep (timing isn't critical), a LiPo battery and a solar panel. To move this out of the sunshine, I'm thinking I could use a clock with alarm function to trip the relay.
As long as you have a mechanical movement it will work... But with a solar panel, deep sleep should also be ok, I think. Unless your have sensors which cannot easily be switched off.
Great video. Very informative. Thanks Andreas.
:-)
Blessed to have ppl like you... Great Sharing (y)
:-)
Really cool stuff! I'm going to use this to make a mailbox notifier! 👍🏻🙂
Thanks! My mailbox unfortunately is out of range for the WiFi. So, I will try to use a "Sub GHz" system like LoRa
Excellent practical use for these esp chips
:-)
As usual, an excellent video, keep up the good work.
Thank you!
Nice work. Always an educational experience.
Thanks! :-)

Very cool idea with the relais!
The relay was only for explanation. In reality we use transistors.
The relay is a brilliant idea.
:-)

Hi Andreas. I am a new subscriber. What great tutorials!
Welcome to the channel! And Thank you.
Hi, very interesting how to put esp info "sleep". Thank you for your video.
You are welcome!
Very nice video, and I'm so glad that you did not go with the relay solution... waaaaay too much power required, even if only for the short time while the microcontroller runs. I was looking for a latching "soft power on" circuit that does not draw any power when off and haven't found one yet, but they must exist... at least I hope so. Cheers,
+jims408 I used the relay because it is easier to understand. As always, it has advantages and disadvantages. For a button used only very rarely (e. g. Emergency button, this could still be a good solution because it draws absolutely no current during off.
Some LDO regulators have CE, but I do not know how much current they need in the off state.
Thanks for doing this channel!👍👍
You are welcome!

I like your videos and pizza! More relevant to this video, a CMOS logic chip could operate at a very low power level until it wakes up with the press of a momentary button, then enable/supply power for a desired time, then sleep/deactivate your circuit. I used a 9V battery in such a CMOS logic circuit for 30 years and it still worked, although it was in stand by almost the entire time.
I think this is a good idea if you need some logic. And it is astonishing that it worked for so long (also because some batteries discharge themselves).
If you just need a mechanical switch you also can go with a simple MOSFET to switch the ESP on ( I used this principle in another video)
Great stuff!!! Thanks Andreas!
You are welcome!
so many great ideas. you rock!
:-)
I like your projects!
+Henrik Worg :-) thanks!
Great video! Keep them comming!
Thanks!
I have used a similar concept for my mailbox but instead of just a p-channel mosfet I also added an ATtiny85. It waits in deep sleep for an external interrupt (or two) and powers the ESP8266. When the ESP is done is signals the ATtiny to go into deep sleep. In deep sleep th ATtiny and mosfet together use less than 1uA. With the ATtiny you can have more than one interrupt like for on and off buttons. So the same circuit can be used to trigger two separate functions.
That is a very good idea if you need more than one input or if you want to include some logic.
This was interesting. Than you for producing it.
:-)

A comment to support this channel that helps me disposer the esp world. Thanks
Thanks for your support!
Very smart. I had very similar project back in 2007 and I used an external RC circuit to wake up the MCU via IRQ pin. When the Switch is pressed and the Cap is charged the MCU wakes up via the IRQ pin. When the Switch is released the Cap is discharged via R and the MCU is powered off. So you press the Switch and the Cap charges via the Resistor, it reaches the trigger level - when you release the switch the Cap begins to discharge until the MCU is shut down. It worked perfect - I didn't care about time precision for when the MCU should shut down. You may use an SCR device with low channel resistance (and a Darlington Transistor - if having weak signal coming from somewhere) as well.
The WiFi connection sometimes can take a long time. This is why I decided the CPU has to switch the power off only when the job is done.
BTW: I made a very similar device where I deep-sleep the device instead of switching it off. Similar to your example, I think.
@@AndreasSpiess That makes sense - thank you.
great channel! It feels like you are my personal professor :D
Thank you!
great work, awesome idea !!!
