Hi Andreas! Very good video, again. Just one tiny remark: If you have no connection from GPIO16 to reset pin, the ESP does not stay in deep sleep. It (kind of) wakes up in a weird state and does not continue to run the code, but consumes about 15mA. So that's even worse than staying in deep sleep. ;-)

Thank you for the great videos, they seriously are very inspiring! With respect to battery runtime I am still trying to figure out which is the best minimal setup for a bare ESP12F module (using FTDI for programming). I understand that you need the following pins connected: CH_PD/EN => Pullup; GPIO0 => Pullup (for running; GND for programming); GPIO15 => Pulldown. And, for stability reasons: GPIO02 => Pullup; RST => Pullup; Electrolytic capacitor 1000uF between VCC and GND (as pointed out in one of your videos). What are the best values for the external resistors (sometimes I read 10k and sometimes “the smaller the better”) if I am looking for minimal energy consumption and/or stability? Some pins have internal pullup/-down resistors would they be a better choice than external ones? And does the maximum voltage level of a capacitor does have any influence on energy consumption? I know, a lot of questions, but maybe you can help shed some light?

Hi Andreas, I have managed to descrease esp 12F's Power consumption to 159uA by removing the LDO of Wemos d1 mini I Power it with my custom deep sleep wake shield. The shield is using 100nf in parallel with 100uF in paralel capacitors to HT7333 then HT7333 3.3v output is connected to 100nF polyester film capacitor for filtering purposes then I added 1000uA 3000 hour lifetime %5 capacitor to reduce peaks as you mentioned in the video. Then this Power circuit Powers my deep sleep wake part of the circuit and that circuit itself with Power components just draw 1uA😀 I also watched your PIR sensor videos and I have choosen HC-SR-501 and modified it by removing Diode cause it was lowering the voltage and removed LDO of it then I bridged VIN and VOut of LDO pins now it draws 36,38 uA when it is idle. When my sensor detects movement the wake circuit wakes esp12F from deep sleep and keeps it open until task is done then it goes to deep sleep again. With modified HC-SR-501 PIR sensor my sensors total current draw is 210uA in deep sleep with clone wemos d1 mini😀 with my calculations it will Last for 346 days with 2000mAh Lithium-Ion battery with 3.8 volts with single charge. Thanks for tips for lowering Power. I am also full time 12 years of experience C, C++ and C# programmer so lowering run times was easy. You can lower your connection time even more. My sensors connects the wifi gateway in 500,600ms if you specify mac address😉 I might remove the blue LED as you suggested for lowering consumption even more! Thanks!

+XerotoLabs I just learned from a viewer that LiPoFe4 batteries with a nominal voltage of 3.2 volts exist. These would be ideal for this purpose because their max voltage is 3.6 volt. So, I ordered some and will try. 9V batteries are a bit of an overkill because the regulator has to "kill" the extra volts. I wonder how much current it would use in deep sleep...

Hi Andreas, Hope you are keeping well.. Thank you for another great video, you just keep getting better and better. I m working with a small solar cell, 2 x 10F super capacitors and a TPS61200, just got the super capacitors today, so testing them now I have been running an ESP from a 4.2v - 3.7v Li ion 18650 through a MP1405 (TP4056 .with battery protection and load cut off) in deepSleep with 60sec cycle. Transmits DHT temp/hum and ADC_VCC to Thingspeak Surprisingly, it tolerates the voltage and has been running for 2 weeks without a glitch. The battery is also fully charged. I know this is naughty, but just wanted to see if it would work. Could it be the deepSleep and short awake time be a contributing factor to this? My ESP 4MB chips arrived today along with my hot air rework gun. Many thanks for making all this possible Andreas, your work and methodology make you a great teacher. Massive thumbs up, keep them coming

+Dean Greenhough I also tried my ESP module with voltages above 3.6 volts, but it was no more reliable. So, I think, you just got a different batch. I do not think, that the on-off time has an influence on this because the main work is the on- time. As I did not respond for a week, I think, you have already changed the RAMs with your new hotair gun ;-) I never worked with super capacitors, so I am interested in how long they are able to power an ESP module. My ESP with 2 AAA batteries on a 2 minute schedule still transmits data to Sparkfun. It is now 16 days since it started.

+Andreas Spiess changing the RAM was shall we say a little tricky. The soldering of the new chip was a little more of a challenge, but you showed us how to deal with that. I have changed 4 chips. I have noted that the ESP 01 black version has a 1mB chip, which is the same size as the 4mB chip, so no alteration to the legs required. I read somewhere that the ESP 01 is less power hungry. So would like to get this working with deep sleep the only issue I have found is attempting to solder such a small wire from RST -GPIO16 😂😂😂 it appears impossible. FYI after I changed the Ram, in all four cases, I could upload. But the program failed to run. After reworking each pin, all went well, so I was to blame. The TPS61200 Tiny Module is proving to be a tricky little module to work with. I have managed 29mins with a single solar cell and 2 X 10F caps. With ESP201 led removed, deep sleep 60s sending DHT22 and mV via ADC to things.

@deangreenhough3479

+Andreas Spiess The TPS61200 I have is factory set to 250mV so acts like a jewel thief, no good for rechargeable batteries. You can alter this, but requires a 0.1F SMD CAP and 2 X SMD resistors ( I have ordered from China) My initial test show that if I can get the UVLO set to disconnect the load at say 3v, disconnect the load, recharge and then run the ESP it should be able to transmit between 1-5 mins later with out any batteries. It all hinges on not depleting them down too far as charging from flat takes a lot of time. I like the fact this can almost be autonomous. In my case I have a known good light source for 12 hours, so whilst my system is running I get data transmitted for free. I would be interested and find it useful if you could possibly do a video with this module and super caps. I have a feeling you would like this module Thank you Andreas

@AndreasSpiess

8 жыл бұрын

+Dean Greenhough My thoughts concerning your comment: 1. What is the advantage to use a super cap with an ESP?. If I have no additional power source, I prefer a power source which has a high energy density. These are usually chemical batteries or at least rechargeable batteries if the device is quite power hungry. If solar power is used, again, a rechargeable battery seems for me the better choice because of its power density and low price. So, I do not see the advantage to use super caps for this purpose (only that they do not need an under-voltage protection) other than curiosity. But, maybe I am wrong. As I said, I do not know this technology. For the under-voltage protection I prefer the method described in the video: Send me an e-mail that I have to replace the battery. The under voltage protection just protects the battery. The mail protects the overall application and makes sure, that I do not "forget" to charge/change the batteries. But this, of course, only applies to connected devices... 2. What are the advantage to use power protectors or boost/buck converters for the same application? As you write, they "steel" valuable power without adding value. I see here the way to go either with a small linear regulator or better, no regulator at all, if battery voltage matches the range of the MCU. This is why I ordered some LIPOFE4 batteries which should fit exactly into the voltage range of our ESPs. From what I read, super caps seem to be quite good for extremely high currents. So, maybe it would be better to do something else with them?

Just found your video's and am really enjoying them. With 2 alkaline battery's what do you consider the minimum voltage before replacing them. You wouldn't even start out with 3.3 vdc and can't imagine that would work.

It is well below 3 volts. You might try it, I did not make exact measurements about this fact. And I am not at home to do the measurements again. As the overlay says, it worket for 19 days with my setup of sending a measurement every 2 minutes.

Hi Andreas, you use also the quite big white board to solder the ESP on it. Do have found in the meantime a smaller version that has the size (width) of the wemos shields? I see still only on aliexpress the white boards from the video. I really like the already included pullup resistors and the place to solder the voltage regulator. All great. Just a little big too big for my outdoor housings.

+Stefan Bode No, I never searched. Maybe you create your own. At Osh park they do not cost a lot...

Thank you so much for your sharing. Your channel help me a lot while working with ESP. Just one question, I know that the regulator of ESP is optional for your White Adapter, and in case of you want to use regulator you need to desolder the short-circuit 0 ohm resistor in the middle, if not your input-voltage connect directly to 3:3V. But you didn't do it there, so I don't know how your ESP can still working ?

There are several versions of this PCB sold

Finally one last video topic suggestion on using the ESP8266, MQTT and security. While I have read on some forums that it is possible to run MQTT securely with TLS1.2 on the ESP using a native C Xtensa development toolchain, it would be really helpful to understand if you have ever explored doing this in an Arduino IDE environment for the ESP8266. Everything I have ever seen with the Arduino IDE is only using unsecured communications. Seems like something seriously holding back the IoT market. A two minute session with Wireshark exposes all hobbiest username/passwords with all of the newest MQTT services.

+Mark Troyer So far I did not try secure communication. I am not sure if it is easily possible ith the EXP8266. My opinion is, that the thigs I transfer are not really important nor are they valuable. So, the chance of a problem is rather small for me. For seure communications we probably have to wait for the ESP32.

great vid. thanks.

This is a great video , thank you for posting. The quiescent current appears to be very large. It would be great if we could power this device for a period of 1 year. any ideas ?

hi there, congrats, great video. What RTC ic you are thinking to use when operating with larger periods? How about make the RTC "wake" the module? Could decrease the 8min operation time? regards,

@AndreasSpiess

I do not want to use any RTC exept the ESP RTC. Then you avoid question #2. What do you mean with "Could decrease the 8min operation time?"

Those 6.3V 1000uF SMD Tantalum Capacitor had a leakage current of around 60uA too.

You are right. I had to learn that fact later on.

Much appreciate your great work. Unfortunately Phant of sparkfun is no longer in operation. I will try with adafruit service and Supercap, solar panel combination for power. Please make some video on energy harvesting for sensors. Danke ;)

I have a LM1117 that i use to provide 3.3v for breadboard projects. It uses 10mA all the time, so not good for battery use. The HT7333 sounds promising for my solar powered esp12.

Interesting video, thanks for sharing! Waiting impatiently for my NodeMcu Lua ESP8266 from ebay :) This will help my future project, want to run on battery for a long time.

Just one remark: NodeMCU boards are development boards and not suitable for low power applications because they use a 5V to 3.3V regulator and have a USB to serial adapter on board. Both devices use lots of power even if the ESP is in deep sleep.

Good to know, I'll look into using a ESP-12 instead of the NodeMCU for the final build then.

Do you think these would work as well (cheaper), or is 4V to low? www.ebay.com/itm/191697227371 Or possibly another capacitor type, space is not an issue for my application.

Looks like there a multiple versions of the ht7333 i discovered that the datasheets are different. Also in your video you are showing the data sheet of another version than the chip itself. Look for ht7333-1 and ht7333-a. Love your video's btw!

I was not aware of the versions. I a later video I tested my HT7333 and their quiescent current was ok. But I saw also two different data sheets. So, thanks for the tip!

No. I didn't. Can you give me a link? Also could you, please, give me advise: If I want to power my ESP8266 from LiPo18650 and will use HT7333 for stabilisation - it means that i will use only part of 18650 capacity, because HT7333 will stop work at 3,45 V (3.3+dropdown). But lower level of voltage on 18650 (fully discharged) is about 2.5 V. how to use it's capacity from 3.45v to 2.5v ?

No, I saw it. It's just what I heard because I was away from the monitor listening to the video. NOT criticizing you, I just thought it was funny. :-)

I was looking for something like the ST1L08 or the LDFM voltage regulator, but it's quite hard to find. I really liked the option to shut it down digitally...

I think, you find also other LDOs with that property, I just do not remember, which one

You have solved the conundrum of the LDO supply by using the ht7333 - ebay ordered already :D
