DIY Automatic Hand Sanitizer Dispenser without Arduino or MCU Circuit Diagram Practical Applications of an Automatic Dispenser. Here are some use cases where automatic dispensers are widely used: Hand Sanitizer Dispensers: Essential for hygiene in homes, offices, and public spaces. Soap Dispensers: Commonly used in restrooms for touchless operation. Food Dispensers: Ideal for dispensing pet food or grains. To design an automatic hand sanitizer dispenser, first, we will need a container to store soapy water. After that, we will need something that will pump soap water and this thing is a DC water pump. The DC water pump will pump out soapy water for us. The electronic hand sanitizer dispenser is based on IC 555. Our sensor-based automated hand sanitizer dispenser senses the ambient light intensity too. When the light emitted from LED on the LDR obstructed by the hands, the resistance of LDR is increased. The LDR along with sensing element 1M potentiometer is connected to 2 and 6 pair of IC 555.
An automatic hand sanitizer dispenser is automated and alcohol based the most important criteria is that it is touch-less machine, which will be used in hospitals, schools, work places and much more.
Automatic hand sanitizer dispenser Circuit Diagram
In this project I will show you how to build an automatic hand sanitizer dispenser. Since the use of hand sanitizers has increased enormously with the Covid 19 outbreak, I thought it would be a good idea to make a decent non-contact dispenser that also looks presentable. Design. There are already several designs available on the internet. In this project, we create a contactless hand sanitizer dispenser that can be used for any press-to-release hand sanitizer available in the market. The project uses an Arduino Uno, an HCSR04 Ultrasonic sensor, and a servo motor. The system is adjustable to accommodate most sanitizer bottles.
An automatic hand sanitizer dispensing machine was developed using microcontroller as the main brain behind of the system operation. Hand sanitizer dispenser can be used in many public places and Structure foreground. 2. Controller Design. As seen in Figures 4 and 5, the Automatic hand sanitizer device consists of a power supply, sensor, board, motor controller, and motor.The power supply provides voltage and current for the operation of the motor and board, and its power source is a battery.
