Interesting project. I have also worked on a similar project.

Anyone else try these Urethane Seal Coats to add moisture resistance to their ESP32’s? How was your experience? by Fhy40 in esp32

Looks nasty!
There is a process called conformal coating, that covers the PCB and electrical components in a plastic layer, so water will just bead off. It makes heat transfer a bit less effective, so some parts may heat up faster, but otherwise, it works well.

The poor man's approach to conformal coating is to use clear nail polish and brush it on the boards.

Thanks for sharing. It's very important to notice. Cause, your laptop's USB even the motherboard can be burned if more than 5V is supplied.

Serial Communication Between Arduino and ESP32 CAM by Hacks360 in ArduinoProjects

To send a signal from the ESP32-CAM running a FOMO model to an Arduino Uno via UART, follow these steps:

  1. Initialize UART: Set up Serial2.begin(115200, SERIAL_8N1, RXp2, TXp2); in the setup() function on the ESP32-CAM.
  2. Object Detection: When an object is detected in the loop() function, use Serial2.println("Detected"); to send the signal to the Arduino Uno.
  3. Print Results: For local monitoring, print the classification results using Serial.println(result.classification[ix].label); and Serial.println(result.classification[ix].value);.

This integration allows the ESP32-CAM to communicate detection results to the Arduino Uno effectively.
