In reply to Dusan.

We have this guide about the BME680 that might help: https://randomnerdtutorials.com/esp32-bme680-sensor-arduino/

Hello. Has anyone replaced the BME280 sensor with the BME680 sensor? Please let me know.

Hello, I purchased an ESP32CAM Ai Thinker board from DIYmore with a micro USB interface that also serves as a power supply. Everything works correctly. When I power the board with an external source, the board no longer turns on. I contacted DIYmore, and they told me that the ESP32CAM only works with micro USB. Is that true?
Thank you for your attention. Best regards.

Hallo ihr Beiden,
bin nach ein paar Jahren zurück.

Hello.
I’m sorry, but the main part of the text fell out. So a correction.
In the sketch section
camera_config_t config;
it is stated
config.pin_sscb_sda = SIOD_GPIO_NUM;
config.pin_sscb_scl = SIOC_GPIO_NUM;
In VS Code, PlatformIO lists the error as obsolete (deprecated) . Offers repair
config.pin_sccb_sda = SIOD_GPIO_NUM;
config.pin_sccb_scl = SIOC_GPIO_NUM;
Thanks,
Dusan.

Hello.
In the sketch section
camera_config_t config;
it is stated
config.pin_sscb_sda = SIOD_GPIO_NUM;
config.pin_sscb_scl = SIOC_GPIO_NUM;
V VS Code points out that this is outdated (deprecated) and needs to be changed to
config.pin_sccb_sda = SIOD_GPIO_NUM;
config.pin_sccb_scl = SIOC_GPIO_NUM;

Great project,

I didn’t see this in the comments, but anyway to code camera to rotate from portrait to landscape, 90 degree shift?

Thanks,

Tim

Hello,
I have to raise the flag and just can’t get any further.
I have invested a lot of time in getting the program to run with a Wrover board, but I keep getting the same error.

The following situation:
I upload the sketch to a Wrover board. Adjusted with the correct camera setting for the Wrover board. Adjusted with my wifi and telegram settings. So far so good.

However, when uploading and starting the board, a picture is automatically sent to Telegram every minute or so, even though there has been no movement.

I have uploaded a simple motion sketch and tested whether the motion detector is defective. but it is not. it works perfectly with the simple sketch.
I uploaded a simple sketch to upload photos to Telegram via /photo. it works perfectly.

However, when I use this sketch above images are sent to Telegram continuously, regardless of whether there is movement or not.
Does anyone have the same problem and possibly a solution?

I have used several boards and PIR sensors. I keep getting the error. I suspect that the camera setting influences the PIR or vice versa.
I have another board with AI-Thinker where the sketch works perfectly. However, I would like to use the Wrover board.

thanks in advance !!
BR

Greetings Sarah and Rui.
A project that I had been putting off for a long time and was now struggling a little. Well it works perfectly, great tutorial.
I don’t know if this will be advertising, but I bought a programmer from the Czech “laskakit.cz”, programming is simplified, everything is included in the board.
Thank you and I wish you a lot of strength in your work and a nice summer.
