The document summarizes a smart tissue dispenser project. The smart tissue dispenser aims to address issues with typical dispensers like waste and exposure to germs. It can control the length of tissue dispensed between 40-50cm and produces a warning when tissues are low. Testing showed the length dispensed varies with weight and is proportional to the motor rotation time. The dispenser is low cost, long lasting, and user friendly but relies on batteries and can only use certain tissue types.

2.  The SMART TISSUE DISPENSER is a solution to fix the problems that
exist with typical tissue dispenser, while adding convenience with the
automated features.
 Smart Tissue Dispenser also can control the over use of tissue.
 It also have the warning mechanism to alert user when the tissue is
almost empty.
 It is a user friendly tissue holder that easy to apply.

3. • wasting tissue and broken because it dispose to water
that are done by user at certain area
• the toilet paper roll exposed to the air so that the toilet
paper can and will be touched by any previous user

4. • To controlled the length of the tissue to be rolled (40 cm to 50cm)
• Produce warning mechanism (Red LED ON) when user short of
tissue paper.

13. MOTOR FORWARD MOTOR REVERSE

14. • When the tissue forward (roll out), the length was different from the other
because the rolling of motor is no accurate.
• The more the weight of the object, the less of the speed it rolling.
• The length of the tissue is depending on the time taken to roll the motor.
• The sensor will detect only one time because using DIFD concept.

LOW COST NO BACKUP POWER
LONG LASTING CANNOT AUTOMATIC REPLACE
USER FRIENDLY ONLY CAN USE CERTAIN TYPE OF
TISSUE
WATER RESISTANCE

18. • The length of tissue paper is proportional to time of motor rotate
• Produce warning mechanism when short of tissue paper
• Rotate forward and reverse a heavy load
• Low cost
• User friendly and easy to apply
