Aim
The aim of the project is to Build a system to remind users to use hand sanitizer regularly.
Problem statement
The system should issue timely reminders to individuals, prompting them to use hand sanitizer for maintaining good hygiene practices. The objective is to create a user-friendly and unobtrusive solution that encourages regular hand sanitization, especially in environments where it is crucial for preventing the spread of infections.
Material used
Input: Ultrasonic Sensor
Brain: TinkerSpace Brain Board
Output: Buzzer and Red LED
Battery: 5V Lithium-ion rechargeable battery
Component description
Ultrasonic Sensor
The function of the ultrasonic Sensor is to detect the hand
Buzzer
Buzzer is used to make sound when ultrasonic sensor detects a person.
RED LED
Red LED is used to Glow when ultrasonic sensor detects a person.
TinkerSpace Brain Board
TinkerSpace board acts as brain of this project, its function is to monitor ultrasonic sensor and control the Buzzer and Red LED
Battery
5V Lithium-Ion battery is used to power-up this project
Working description
Case 1: When the person is detected, Ultrasonic sensor turns ON and sends the signal to the brain board. The brain board turns on the Buzzer to 100% and brightness of red LED to 100%
Case 2: When no person is detected, Ultrasonic sensor turns OFF and sends the signal to the brain board. The brain board turns on the Buzzer to 0% and brightness of red LED to 0%
Circuit Design (DesignSpace)
Step 1: Connect Ultrasonic Sencor to input 3
Step 2: Connect BUZZER to output 1 and RED LED to output 2
Step 3: Connect supply and test project.
