Re: Batterylife of D32 with Plantsensor and 700mAh Battery
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...

Re: Wakeup mode
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?

Re: Batterylife of D32 with Plantsensor and 700mAh Battery
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...

Re: Batterylife of D32 with Plantsensor and 700mAh Battery
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...

Re: ESP32 and Annoying Soil Moisture Sensor
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 ...

Batterylife of D32 with Plantsensor and 700mAh Battery
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...
