About the project
Blog electe. blogspot. compositions itself as a resource for electrical engineering. Judging by the structure and content, this is a personal or highly specialized project, where the author shares practical experience in the field of microelectronics and programming. The main theme is the use of available modules to create smart devices.
The site has been actively publishing articles since 2020, and in recent years (2024-2025) the publication of posts has become regular, approximately once a month. This suggests that the project is alive, supported and developing, and is not an abandoned archive.
Main directions
The blog content is focused on hardware and its software implementation. The author analyzes specific cases of using popular platforms. In particular, a lot of attention is paid to the ESP32-CAM modules.
- Automation of shooting:Describes the creation of video surveillance systems that are activated only when movement occurs. This is done using a combination of an ESP32 camera and a pyroelectric sensor (PIR).
- Saving resources:The author emphasizes the importance of saving SD card space and energy. The camera does not record video continuously, but takes pictures only when it captures warm objects - people or animals.
- Data storage options:Two ways are being considered: saving to a local memory card (convenient for remote places, for example, in the forest) and sending photos via Wi-Fi to a server or to Telegram (if there is Internet).
- Programming:The blog offers ready-made solutions. For example, you can take a standard sketch for a camera and modify it by connecting an external sensor without having to write code from scratch.
Features of the site
The site has a pragmatic approach. There is no complex theory here, only applied instructions. The author explains exactly how to connect the components: for example, the output of the PIR sensor transistor needs to be soldered to the button pin, which is connected to the Reset pin of the microcontroller, since there is often no separate Reset pin on the ESP32-CAM board.
An interesting detail is the presence of a calculator right on the page. It allows you to perform simple mathematical operations, which can be useful in calculating circuit parameters.
It is also worth noting that the project exists in a blog format with an archive by year and month. This is easy to navigate if you are looking for a specific article from a specific period. In 2025, an article about automatic shooting has already been published, which confirms the relevance of the materials.

This is typical for independent technical blogs, where the authors live off enthusiasts.
FAQ
How does automatic shooting work on the ESP32?
The system uses the ESP32-CAM module paired with a pyroelectric motion sensor (PIR). The camera goes into standby mode and takes a photo only when the sensor detects the movement of a warm object. This allows you to save battery power and memory card space.
Is it necessary to write new code for such a camera?
Not necessarily. You can take a ready-made sketch for a camera, which is already on the blog, and simply supplement the circuit with an external PIR sensor with a transistor inverter.
What to do if there is no Wi-Fi nearby?
If there is no Internet, for example, in the forest, the camera will save photos directly to the SD card. The data can be retrieved later by removing the card.
How to connect a motion sensor to the board?
The transistor output from the sensor must be soldered to the button pin on the board. This pin is connected to the Reset pin of the microcontroller, since there is usually no separate Reset pin on the standard ESP32-CAM board.
