That's awesome!
Thats a whole Kickstarter campaing that you just skipped and delivered a working product!
Call me impressed.

we can use a powerbank connected to the system in double use, i.e to charge battery and to power the esp32? Yes, if you use a Powerbank and connect it via USB to the ESP32, it will power the ESP32 and charge the LiPo Battery at the same time. At least on the Lolin D32. You can see that on the first...

3 Years later i have the exact same question.

My Buttons are default HIGH and i want to wake up the device if any of the 3 Buttons is pressed.
Using Pin 34, 35 and 39.
There is no way to inverse the pins in Deep Sleep is there?

This guy seems to have found a way around that.

Batterylife with 60 seconds and Offline Sensor: (update 1+2) Not sure how much i can trust these cheap Voltmeters from china, especially on extremely low currents (it does show 0.05A when nothing is connected at all....) But according to this the sensor draws 260mA at ALL times. https://i.imgur.com...

Update 1: Batterylife with 600 sec aka 10 Minute interval is only abysmal better than 60 seconds. This points to Issues with Standby and not Active time. Removed the 3.3V from the Sensor and plugged it in pin27. Now i have to turn on Pin27 whenever the ESP leaves Deepsleep. No more useless current d...

The start and end of ADC are not entirely accurate :( https://i0.wp.com/randomnerdtutorials.com/wp-content/uploads/2019/05/ADC-non-linear-ESP32.png?w=768&ssl=1 https://randomnerdtutorials.com/esp32-adc-analog-read-arduino-ide/ By the way, if someone is going to redesign the board to include a batter...

Mine works pretty fine with a Lolin D32 and this code: you can omit the UDP send part and activate Serial instead for debugging. #include "WiFi.h" #include "AsyncUDP.h" const char * ssid = "***"; const char * password = "***"; AsyncUDP udp; float asoilmoist=analogRead(32);//global variable to store ...

Introduction: Howdy, I've finished my Plantsensor with a Lolin D32 a Soil Moisture Sensore v2.0 and a 700mAh Battery . Now that it works i've wanted to share some results :) https://i.imgur.com/MQcwYbb.jpg (Yes... that Cable from vBat to GPIO33 doesn't exist anymore... first time with a ESP32 board...
