Aim
The aim of the project is to build a dust-bin which opens/closes its lid automatically.
Problem statement
Most of the dust bins are kept open which emit bad odour and leads to air-borne diseases. Even if it is closed, the lid of the bin will be dirty, and people refuse to open the lid with hand. In order to fix this issue, we introduce the smart dust bin which opens and closes by sensing the hand gesture.
Material used
Input: IR Proximity Sensor
Brain: TinkerSpace Brain Board
Output: Servo Motor
Battery: Lithium-ion rechargeable battery
Component description
IR PROXIMITY SENSOR
The function of IR proximity sensor is to detect person and send the signal to the Brain unit (TinkerSpace board).
SERVO MOTOR
The function of the servo motor is to open or close the dustbin.
TinkerSpace Sensor Board
TinkerSpace board acts as brain of this project, its function is to monitor Rain sensor and control servo motor.
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
Case – 1: When the hand is detected, the IR proximity sensor (input) turns ON and sends signal 1 to the TinkerSpace brain board (brain). The sensor board opens the lid of the dust-bin with the servo motor (output).
Case – 2: When no hand is detected, the IR proximity sensor turns OFF and sends signal 0 to the TinkerSpace brain board. The sensor board closes the lid of the dust-bin with the servo motor.
IR proximity sensor ON —> Angle 90°
IR proximity sensor OFF —> Angle 0°
Circuit Design (DesignSpace)
Step 1: Open TCode App -> Create New project -> Open DesignSpace
Step 2: Connect IR PROXIMITY Sensor to INPUT 1 of the Brain board.
Step 3: Connect Servo Motor to Output 1 of the Brain Board.
Step 4: Connect supply and test project.
Model ideas
Plan to build a dustbin or take a theme of bus stand or hospital
