ESP32 Deep Sleep - Power latch, TPL5110, and more | Part 2

This project is sponsored by PCBWay, order your PCBs now for only $5: www.pcbway.com/orderonline.aspx
In my last video, I developed the first prototype of a smart door and window sensor, and over the past few weeks, I have done several tests to investigate a better solution for deep sleep, trying to reduce the device's power consumption as much as possible.

In the video I do not show how the attiny10 works, simply because I preferred to find a simpler solution to the problem. I preferred to develop a power latch(which I will show in the next video) instead of optimizing a dual microcontroller solution.

That's a really interesting topic... It can be extremely complicated when trying to achieve the most of a coin-cell or a battery. I will be tuned for new updates ;)

[@princebanini]

this is an incredibly nice project. i'd subscribe to learn more about this

[@roblatour3511]

This is great, after watching this video I watched an earlier video of your describing what you're doing overall. Fantastic. Regarding this video, its the type of solution I am looking for - but out of curiosity how do you tell the power latching device when to do the next wake-up. I know the Adafruit TPL5110 solution uses a potentiometer, but as you are having your power latching board connect to your esp32 board I was wondering if you had given thought to have the two boards share some sort of common memory chip through the interface such that the esp32 could write to it and the power latch module read from it to know how long to wait to turn the esp32 back on.

Thank you for your comment, developing a power latch with programmed awakening of ESP32 is more complex. The TPL5111 as you well said does not do that at all. There are other ICs that have similar functionality by giving the possibility to program them via I2C bus. I plan to develop solutions like these in the future.

That quick connector is really good, modular type design
What are that things called?

[@SalvatoreRaccardi]

Slimstack connector by hirose

Ive designed one with TPL and 18650 battery. I plan to use coin cells but unlike normal batteries, coin cells, especially single cell, won't be able to sustain if it needs to wake up 10 times per day, where each wake up is 5 to 10 seconds. From my prediction that is.

[@SalvatoreRaccardi]

I plan to use two batteries AAA, but not with TPL. I designed a custom power latch.

Great project. Only friendly suggestion to you is "please improve your audio recording (mic)", very difficult to understand, thx.

[@SalvatoreRaccardi]

Audio level? Or distortion?

[@robinjansen51]

I think that the sound is ok 👍

[@andhuruh]

can you do one with sim card capabilities instead of WiFi

[@SalvatoreRaccardi]

yeah great idea, thank you!
