Battery Voltage Level Monitoring Circuit When you have your ESP32 powered with batteries or solar powered as in this case, it can be very useful to monitor the battery level. One way to do that is reading the output voltage of the battery using an analog pin of the ESP32. However, the ...
I've searched the forums for any methods for esp32s3 chip input voltage (3.3v) monitoring and found nothing. I assume this would be a common issue for battery powered applications. So I have two questions : 1. Is there a API function specifically for monitoring the esp32s3 3.3v chip in...
Using a pair of nRF24L01 transceivers, have coded a way to switch a battery remotely, put the ESP32 to deep sleep and wake-up using external 0, RTC_GPIO. Coded a way to accomplish task of remotely switching a battery, switching is by Async web server request. Request determines on/off ...
The battery voltage is used for: Providing battery status to the LoRaWAN network server on request Battery deep-discharge protection and energy saving mode Monitoring battery status via uplink (e.g. for optimization of transmission interval) Caution The following section is meant as a general intro...
The LCD will display the IP address of the HTTP server Use a web browser to log in to the IP address: 192.168.4.1. Control the LCD of the ESP32-S3-GEEK through the buttons on the server. Press different buttons and observe the changes on the LCD. For more display functions of the ...

In this project, you’ll learn how to host an ESP32 web server and use ESP-NOW communication protocol at the same time. You can have several ESP32 boards sending sensor readings via ESP-NOW to one ESP32 receiver that displays all readings on a web server. The boards will be programmed...
pin-breakouts, this board can can also serve as a general-purpose ESP32/RFM95W development platform. So, instead of using it as a LoRaWAN gateway, you can turn it into aLoRa device, and use the powerful ESP32 microcontroller to monitor sensors, host a web server, run a display or more...
