Aim
The aim of the project is to Build an automatic hand sanitizer dispenser with a motion sensor for touchless use.
Problem statement
The system should be designed for easy integration into public spaces, ensuring efficient and touch-free hand hygiene. The goal is to provide a convenient and hygienic solution that encourages regular hand sanitization, particularly in high-traffic areas, contributing to the prevention of infectious diseases.
Material used
Input: IR Proximity Sensor
Brain: TinkerSpace Brain Board
Output: Water Pump
Battery: 5V Lithium-ion rechargeable battery
Component description
IR PRoximity Sensor

The function of the IR Proximity Sensor is to detect the hand
Transistor switch + Water Pump

Water pump is used to dispense the appropriate amount of sanitiser.
TinkerSpace Brain Board

TinkerSpace board acts as brain of this project, its function is to monitor water level sensor and control the water pump
Battery

5V Lithium-Ion battery is used to power-up this project
Working description
Case 1: When the hand is detected, IR Proximity sensor turns ON and sends the signal to the brain board. The brain board turns on the Water pump
Case 2: When no hand is detected, IR Proximity sensor turns OFF and sends the signal to the brain board. The brain board turns off the Water pump
Circuit Design (DesignSpace)
Step 1: Connect IR PROXIMITY SENSOR to input 1
Step 2: Connect TRANSISTOR SWITCH(with WATER PUMP) to output 1
Step 3: Connect supply and test project.
