In this Instructable, We will Implement Entry Controlled Parking Using Servo Motor and PIR with LinkIt One Board.
A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity and acceleration. It consists of a suitable motor coupled to a sensor for position feedback.
A passive infrared sensor (PIR sensor) is an electronic sensor that measures infrared (IR) light radiating from objects in its field of view.The term passive in this instance refers to the fact that PIR devices do not generate or radiate any energy for detection purposes. They work entirely by detecting the energy given off by other objects.PIR sensors don't detect or measure "heat"; instead they detect the infrared radiation emitted or reflected from an object.
Step 1: Requirements
2.Servo Motor(2-3 kgf-cm)
3. LinkIt One Board
4. 15cm Ruler Scale(for prototype presentation)
5.Double side tape
Step 2: Connections
PIR to LinkIt One Board:
5V - 3.3V(Since servo requires more current for performance)
GND - GND
OUT - D3
Servo to LinkIt One Board
After these connections, stick the ruler scale over the Servo motor and place the servo on the ground with the help of double tape so that it should remain firm.
