This repository provides the code to operate an ESP32-CAM module to stream static images over Wi-Fi. Then a Raspberry Pi can process those images locally to detect people around it.
The source code is a modified version of this ESP32-CAM example sketch.
Apparently, there are variants of the ESP32-CAM module, and some of them are NOT 5V tolerant. However, the micro-USB programming board provides 5V, which can damage the ESP32-CAM module. We should be careful while buying the module-programmer pair and double-check whether those are 5V tolerant.
Additionally, we can program the 3.3V variants with an FTDI USB to Serial Converter. Make sure to switch the jumper to 3.3V first.
Although some tutorials suggest using the ESP32 Wrover Module board, I could NOT make it work with my ESP32-CAM. Then, I used the AI Thinker ESP32-CAM board, and it worked like a charm.
It is recommended to set a slower upload speed (115200 baud) to ensure stable serial communication between the module and the computer.
New patches and stability features will be added over time.
