Introduction
This project implements a smart camera system which can be used for wildlife photography. In forest, a camera person need not be present to wait for animals to come so that he can take pictures or video. Camera need not be on continuously. It should get on only when there is a detection of motion nearby. Also the camera should track the animal once an animal comes within the range of PIR sensor.
In this project, we have implemented a self contained camera system using STM32L Discovery board and Passive infrared sensor for motion detection. Also a stepper motor is used to rotate the camera and point towards the animal. A magnetometer is used to bring the camera position to null at power on. An accelerometer is used to detect the camera fall.
Hardware Platform
- 1. STM32L discovery Board (Main controller)
- 2. Magnetometer (For bringing Camera to null at power on)
- 3. Accelerometer (For camera fall detection)
- 4. Stepper motor (For Rotating camera towards detected animal)
- 5. Relay Circuit (For controlling power to Camera)
- 6. LDR based circuit (For night detection to switch on flash light)
- 7. Passive infrared sensor (PIR) for motion detection
Main Features
- – Automatic power on for camera once motion is detected
- – Automatic power off for camera when motion is not detected for 20 seconds( which can be programmed)
- – Bring Camera position to null at power on
- – Track the object once it is detected
