Sanitizer dispenser circuit diagram. D1 is an ir transmitter diode and r1 limits the d1 current in other words it determines the sensor s sensitivity. There is an ultrasonic sensor in the machine which detects your presence there. My selected one is a glass horlicks container. The ultrasonic sensor has two.

In this video i ll be showing you the circuit diagram and code for my previous autonomous sanitizer dispenser video. Keep your hands clean by filling it with liquid soap hand sanitizer or with rubbing alcohol. Diy automatic hand sanitizer dispenser. This project will use arduino ultrasonic sensor water pump and hand sanitizer.

The circuit diagram shown below make sure to wire it up accurately. For powering the circuit and the motor a 14500 li ion cell is used and it is connected with a usb charging circuit. D1 is an ir transmitter diode and r1 limits the d1 current in other words it determines the sensor s sensitivity. Vcc and gnd pins of the relay are connected to vin and gnd pins of esp32 while the input pin of the relay is connected to the d19 pin of esp32.

In this paragraph we will talk about how does the automatic hand sanitizer works. Diy automatic alcohol dispenser no arduino needed. The complete circuit diagram for this covid19 tracker automatic hand sanitizer dispenser machine is given below. The water pump is connected to the esp32 through a relay module.

Schematic diagram of the automatic hand sanitizer dispenser first design d2 indicates the proper power connection and r5 limits the led current. How does it work. An ultrasonic sensor is used to check the presence of hands below the outlet of the sanitizer machin. This is the last step.

Otherwise this project won t work. In this project we will build an auto hand sanitizer dispenser. Figure 1 schematic diagram of the automatic hand sanitizer dispenser first design d2 indicates the proper power connection and r5 limits the led current. For example you can use it in dispenser and coffee machine etc.

Power on the automatic homemade sanitizer circuit using the usb cable. So you need to put your hand in front of the sanitizer machine only and the sanitizer machine will give you the sanitizer in your hand till your hand present at the same location. Schematic diagram of the automatic hand sanitizer dispenser first design d2 indicates the proper power connection and r5 limits the led current. For the sanitizer container you can select any similar glass or plastic container such as a plastic coffee storage container.
