Hand Sanitizer Dispenser Circuit Diagram

The complete circuit diagram for this covid19 tracker automatic hand sanitizer dispenser machine is given below.

Hand sanitizer dispenser circuit diagram. Then i tested everything is working by connecting the charger. Schematic diagram of the automatic hand sanitizer dispenser first design d2 indicates the proper power connection and r5 limits the led current. Keep your hands clean by filling it with liquid soap hand sanitizer or with rubbing alcohol. In this automatic sanitizer dispenser design the r1 c1 is calculated to produce an approximately 1 second output high in response to a low signal at pin2.

D1 is an ir transmitter diode and r1 limits the d1 current in other words it determines the sensor s sensitivity. 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. An ultrasonic sensor is used to check the presence of hands below the outlet of the sanitizer machin.

By reducing physical contact an automated dispenser keeps virus from spreading. There is an ultrasonic sensor in the machine which detects your presence there. This project will use arduino ultrasonic sensor water pump and hand sanitizer. Automatic homemade sanitizer can be used almost everywhere for example you can use it in dispenser and coffee machine etc.

In this project we will build an auto hand sanitizer dispenser. In the middle of the container cap and bring out the wire of the motor through the hole and soldered according to the circuit diagram. In this paragraph we will talk about how does the automatic hand sanitizer works. 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.

Diy automatic alcohol dispenser no arduino needed. When the pir detects a human hand it conducts and switches on the bc547 transistor which in turn triggers the pin2 of the ic. That is when the valve is turned on it will consume about 700ma to keep the valve turned on. No microcontroller is required.

The complete circuit diagram for arduino based water dispenser is shown below the solenoid valve used in this project is a 12v valve with a maximum current rating of 1 2a and a continuous current rating of 700ma. Note if you have given a to make this sanitizer share it s a picture in the comment section. Arduino based door lock system. Diy automatic hand sanitizer dispenser.

D1 is an ir transmitter diode and r1 limits the d1 current in other words it determines the sensor s sensitivity. We would love to see it thank you suggestion.
