1 Project report By Rishi Gaurav Bhatnagar (1BI10TE039) Samarth N Shreyas C Under the guidance of (1BI10TE042) (1BI08TE049) Mrs. Rajeswari, Assistant Professor -Internal Guide Prathap R., Head R&D- Li2 Innovations- External Guide DEPARTMENT OF TELECOMMUNICATION ENGINEERING BANGALORE INSTITUTE OF TECHNOLOGY

2 The motivation behind the project was creating an autonomous system that and a scalable model developed around the idea of image capturing of a diversity of animals in the national parks and wildlife sanctuary. Motion sensitive camera traps offer a visual sensor to record the presence of a species at a location, recording their movement. A wildlife research tool combining low cost, ruggedness, low weight, long battery life, threat detection and sufficient picture quality for individual animal identification was designed for the same.

3 Camera traps Camera traps is a technology that facilitates the detection and capture of the movement of animals in wildlife. Camera trapping is a method for capturing wild animals on film when researchers are not present, and has been used in ecological research for decades. research applications include studies of nest ecology, detection of rare species, estimation of population size and species richness, as well as research on habitat use and occupation of human-built structures.

4 Advantages of using a Camera Trap Non-invasive: by only capturing photographs with invisible IR flashes, camera traps have no effect on animal behavior. Low labor: camera traps are easy to deploy and can function for weeks with no attention Robust data: photographs are analogous to museum specimens in being a permanent record of date, location, and species. Bonus material: In addition to recording the presence of a species camera traps can record animal behavior which can be important for scientific analysis.

5 Problem Statement : There is a need to provide a low cost solution to facilitate the survey of various animal species in the areas which are un-approachable by the humans. Shortcomings of prevailing solutions : They have low image storage capacity. Lack of transparency with respect to the equipment status. Lack of anti-theft measure.

6 Objectives : To provide a camera trap with better picture quality. To reduce the cost significantly and make it more affordable. To provide a communication link for the camera traps following the ideology of Internet Of Things To provide a safety mechanism.

8 The proof-of-concept prototype was designed around the following equipment : 1. Camera Nikon D Shutter Release for the camera MC-DC2. 3. Sensors used : Sonar Sensor (MaxBot EZ_1), Accelerometer ( ADXL335). 4. For communication : Bluetooth (HC-05). 5. Processor board for integration and implementation Arduino Uno-R3 6. Receiver- Android mobile with blueterm application.

9 The camera used for the proposed work is a Nikon D3100 with a 14.2 Mega Pixels. Standard 18-55mm lens kit is used. Lens kit at 18mm is used for carrying out the experiments. 18mm at f/3.5 gives the estimated settings of the camera we intend to use in the final product i.e wide-angle and low Depth Of Field. Images are stored in JPEG and/or RAW format.

10 The camera can be triggered in various ways. To externally trigger the camera, we use a camera trigger MC-DC2. The cable was hacked into to be controlled by arduino.

11 Sonar Sensor : Sonar sensor are useful ultrasonic rangefinders. They are capable of giving readings from 0 to 255 inches. It operates at 42KHz with pulse width of 147 micro seconds/inch.

12 It s an electromechanical device that measures acceleration forces. Accelerometer senses in all three directions( X Y Z)

13 Bluetooth device HC-05 It is designed for transparent wireless serial connection. It is a fully qualified Bluetooth with 3Mbps modulation, with complete 2.4 GHz radio transceiver and baseband. It uses Adaptive Frequency Hopping for transmission and has an in-built antenna and EDGE connector.

15 The entire code of the program has been written and executed using Arduino IDE. Why Arduino IDE : 1. Simplicity of the usage of libraries. 2. Serial communication simplified. 3. Open-source hardware and software. 4. Ease with which the PCBs can be designed around Atmega No fees for commercialization for the product.

16 The implementation and interfacing included the following steps : 1. Interfacing ADXL335 with arduino. 2. Interfacing Sonar Sensor with arduino 3. Interfacing HC-05 with arduino. 4. Integration of ADXL 335 with Sonar sensor and serial communication through HC-05.
