 The aim of this project is to use the Arduino platform to allow the smart bird house to monitor bird activity remotely. This is done by capturing images when motion is detected. A small camera, combined with an ESP32 microcontroller, and a Passive Infra-Red (PIR) motion sensor which is compatible with an Arduino microcontroller can successfully carry out this task. All images captured are stored on a microSD card which can be easily accessed later. For this project to remain environmentally friendly, a solar panel is used to charge a Lithium Polymer (LiPo) charger which charges a battery. This is also connected to the microcontroller allowing it to be powered.

 The breadboard helps with easy electrical connections to multiple electronic components, like the ESP32 camera, PIR motion sensor and the Solar LiPo Charger, without needing to continuously solder the necessary parts. This also allows the connections to be temporary and easy to disassemble and reassemble. The jumper wires also aid significantly in these connections as seen in the photo below.

 ==ESP32 Camera==
 The ESP32 camera is a combination of an ESP32 microcontroller and an OV2640 2 Megapixels camera module. This combination is advantageous in this project because it is low cost, low power and easily adjustable. The camera is easily programmed using the Arduino IDE software to write and upload a set of instructions like capturing images and even videos. The microcontroller is equipped with Wi-Fi and Bluetooth potential which makes it easier for DIY or IoT projects. Even though the ESP32 camera had the ability to transmit images or videos to a secondary location using its Wi-Fi and Bluetooth features, it was not incorporated into this project. Since the camera module was equipped with a microSd card slot, which is featured on the ESP32 S chip, this was our preferred method of retrieving the data. Several GPIOs can also be found on the ESP32 camera to connect the sensors and peripherals.

 The Passive Infrared (PIR) motion sensor is a module used to detect changes in infrared radiation which is emitted by humans and animals. This sensor is called ‘passive’ because it simply detects the changes in infrared radiation and does not emit it themselves.  The digital output signal provided by the sensor is HIGH (1) when it detects motion and LOW (0) when no motion can be detected. The PIR motion sensor used at first has two noticeable potentiometers: one to adjust sensitivity and the other to adjust the delay time. The Seeedstudio mini PIR motion sensor produced a better output for this project. Its 20mm x 20mm x 12mm size made it easier and  more flexible to handle. The most optimal detection distance is 2m but this sensor has a range of up to 5m.

 In order to configure the ESP32 camera with Arduino, the UartSBee V5 was used. It is a device that establishes communication between the USB port of a computer and a serial (UART) interface of a component or system. This facilitates programming, debugging, monitoring and uploading of the necessary software for the interaction to occur. The UartSBee V5 configuration of the ESP32 camera with Arduino therefore allowed the code required to be saved and aided in the connection of the motion sensor.

 The Solar LiPo Charger charges the Lithium Polymer battery using a few different power sources like USB, DC power supply or solar panels. Keeping with an environmental theme for this project, a solar panel was used. This charging module is therefore charged by utilizing solar energy from the Sun and this makes it suitable for this outdoor birdhouse. These chargers also contain built-in protection systems to prevent overcharging or over-discharging of the battery.

 Solar panels, or photovoltaic panels, harness the sunlight in order to convert it into electricity. The solar panel consists of multiple solar cells which are all connected to increase the overall current and voltage output to be used to power electronic devices or even charging batteries, as is done for this project. This source of sustainable and renewable energy reduces and mitigates severe environmental impact.

 Deep sleep mode of the ESP32 reduces the amount of power consumed while in operation, but enough power is left to keep the processor and RTC peripherals running. When in deep sleep mode, the CPU, Wi-Fi and bluetooth are disabled. This power-saving feature is quite useful in extending the battery life. When the ESP32 camera is stimulated, in this case by the motion sensor, it will wake up and function as normal.

 In the end, the system worked harmoniously only when charged using the solar panel but overheated when charged with a computer. The figure above shows some photos that were taken when motion was detected. It was also clearly seen that the photo counter worked well as the images were labelled in its respective order. It was also noted that there was a delay with the sensor causing a delay in the photos taken even though movement was constant. There could have been an error due to faulty components or that the general setup had a wiring mishap. With more time and more discussions, the bird house can function without errors.

 =====Challenges and Improvements=====
-The ESP32 camera and PIR motion sensor was first configured using two separate microcontrollers, i.e. the Arduino Uno board, and then later put together using the breadboard. This was one of our biggest challenges because most of the pins of the microcontroller were used, and transferring it onto the breadboard required a different approach with a different code and a more complicated setup. Additionally, it was needed to program around 3 different brands of motion sensor because they were not working. In the end, it was still difficult to get the motion sensor to function continuously. It could also be that the components used were faulty.
