Motion Sensing radar with automated lock system

The purpose of the project was to build a motion detection radar, using simple passiveinfra-red (PIR) sensors, microcontroller (UNO R3), H-bridge, servo motor and radar.Functionality of the project is to capture an image or click a picture of an object or ananimal in motion, sensed by the PIR sensors.The setup of the project contains, two PIR sensors that are placed in oppositedirections and are connected to the UNO R3. A radar is mounted on the servo motor. Theservo motor is connected to the UNO R3 with the help of H-bridge and the trigger of radar isconnected to the UNO R3 using a transistor. The complete circuit is powered using batterieswith the help of voltage regulators.Whenever a motion is detected by any of the PIR sensors, that sensor sends out asignal to UNO R3 indicating a motion has been detected. Now the UNO R3, first, rotates theservo motor in the direction of the motion sensed and second, after the motor rotation iscomplete, it triggers the radar and issues an alert. Assuming the instance that both thePIR sensors have detected motion at the sametime, then PIR-1 has been given as thepriority and the UNO R3 rotates the radar in the direction of PIR-1 and triggers lockmechanism
