Aim
The aim of the project is to Use sensors to detect if someone is at their desk and adjust office systems accordingly
Problem statement
The system should be capable of accurately detecting whether someone is present at the desk or has left, triggering actions such as turning off lights, locking the computer, or adjusting environmental settings. Consider factors like reliability, energy efficiency, and user privacy in creating a solution that enhances workplace efficiency and comfort.
Material used
Input: IR Proximity Sensor
Brain: TinkerSpace Brain Board
Output: Transistor switch (with DC motor) and LED Lamp
Battery: 5V Lithium-ion rechargeable battery
Component description
IR Proximity Sensor
The function of the IR Proximity Sensor is to detect the person
Transistor Switch + DC Motor
DC motor is used as fan here.
LED LAMP
LED lamp is used as desk lamp to read books.
TinkerSpace Brain Board
TinkerSpace board acts as brain of this project, its function is to monitor IR Proximity Sensor and control the LED Lamp and DC motor
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
Case 1: When the person is detected, IR Proximity sensor turns ON and sends the signal to brain board. The brain board sends the signal to turn on the DC Motor and LED lamp on 100%.
Case 2: When no person is detected, IR Proximity sensor turns OFF and sends the signal to brain board. The brain board sends the signal to turn off the DC Motor and LED lamp off 0%.
Circuit Design (DesignSpace)
Step 1: Connect IR PROXIMITY SENSOR to input 1
Step 2: Connect TRANSISTOR SWITCH(with DC MOTOR) to output 1 and LED Lamp to output 2
Step 3: Connect supply and test project.
