In this exciting tutorial, we'll show you how to build your own security camera using an ESP32-CAM and an AM312 PIR sensor to detect motion. Best of all, the photos will be saved directly to an SD card!

Throughout this video, we will guide you through the following steps:

Hardware Connection: We will show you how to connect the ESP32-CAM and the AM312 PIR sensor to your breadboard, ensuring proper power supply.

Arduino IDE Setup: You will learn how to set up the development environment in Arduino IDE to work with the ESP32-CAM and select the appropriate board.

Programming: We will provide you with the code needed to configure the ESP32-CAM and program it to capture images when motion is detected. We will also show you how to store the images on an SD card.

Real-Life Test: You will see our motion detection system in action. We will test it in a real-life environment so you can see how it works.

Tips & Customization: We'll share some helpful tips and show you how to customize and extend this project to your needs.

This project is perfect for creating an affordable and functional security camera for your home, office, or anywhere you want to monitor.

Description

FTDI Basic Program Downloader USB to TTL FT232RL 3.3V 5V DTR

This is a basic breakout board for the FTDI FT232RL USB to Serial IC. The pinout of this board matches the FTDI cable to work with official Arduino boards and cloned 5V Arduino boards. It can also be used for general serial applications. The main difference with this board is that it brings out the DTR pin instead of the RTS pin on the FTDI cable. The DTR pin allows an Arduino target to automatically reset when a new Sketch is downloaded. This is a really nice feature and allows a sketch to be downloaded without having to press the reset button. This board will automatically reset any Arduino board that has the reset pin on a 6 pin connector.

This board has TX and RX LEDs which make it a bit nicer to use over the FTDI cable. You can actually see the serial traffic on the LEDs to check if the board is working.

This board was designed to decrease the cost of Arduino development and increase ease of use (the auto reset feature is great!). Our Arduino Pro boards and LilyPads use this type of connector.

One of the nice features of this board is a jumper on the back of the board that allows the board to be configured to either 3.3V or 5V (both power output and I/O level). This board ships at 5V by default, but you can cut off the default trace and add a solder jumper if you need to switch to 3.3V.

Description

Esp32 Cam Camera Module Wifi Bt Arduino Ov2640 2mp Esp 32

ESP32 CAM WiFi Module with Bluetooth and OV2640 2MP Camera is a development board that integrates a small camera that can work independently.

The OV2640 2MP camera integrates a 1/4-inch UXGA (1632*1232) CMOS image sensor. The small sensor size and low operating voltage provide all the features of a single UXGA camera and image processor. Through SCCB bus control, it can output 8/10-bit image data of various resolutions such as full frame, subsampling, zoom, and windowing.

The UXGA image of this camera can reach up to 15 frames per second (up to 30 frames for SVGA and 60 frames for CIF). Users have complete control over image quality, data format, and transmission.

All image processing functions including gamma curve, white balance, contrast, chroma, etc. can be programmed through the SCCB interface.

Omni Vision image sensors use unique sensor technology to improve image quality and deliver sharp, stable color images by reducing or eliminating optical or electronic artifacts such as fixed pattern noise, smearing and floating.
