Step-by-Step Construction
Time needed: 1 hour and 10 minutes
If you’re interested in making your automatic homemade sanitizer, here’s a step-by-step guide to help you get started:
- Buy a DC water pump.
The DC water pump is essential to the automatic homemade sanitizer device. Its function is to pump the sanitizer out of the bottle and onto your hands without manual pressing or touching. This is important because it helps to prevent the spread of germs, including the coronavirus.
DC water pumps are readily available in the market, and you can find them at electronic stores or online. When buying a DC water pump, you must ensure it’s compatible with the other components you’ll be using in your sanitizer device. If you need help deciding which pump to choose, you can follow the link to purchase a specific pump recommended for this project. - Medical Pipe
You will need to connect a pipe to the DC water pump. This pipe will transfer the sanitizer liquid from the bottle to your hands. You can use any tube, but the best option is to use a medical-grade pipe, as it will ensure the cleanliness and safety of the sanitizer.
You can easily find such pipes at a local medical store or online. However, if you have any other ideas, feel free to use them and share them with us in the comments section. - Proximity Sensor FC51
We must arrange a proximity sensor called FC51, essential for the automatic homemade sanitizer to work. This sensor is very cost-effective and can be easily found in the market or ordered online from websites like Amazon.
A proximity sensor works on the principle of detecting obstacles, and it can detect the presence of an object without physical contact. In this case, the sensor will detect when a hand is placed under the dispenser and activate the water pump to dispense the sanitizer without any physical contact.
If you need help finding the FC51 proximity sensor, you can buy it online. These sensors are usually sold in packs and cost only a few dollars. Once you have the sensor, you can proceed to the next step. - Transistor TLP 32C
Transistor TLP 32C is a type of optocoupler transistor that is used for switching power to the load. It is a critical component of the homemade automatic sanitizer device, and you should use the same type of transistor to avoid any issues with the circuit.
You can easily find this transistor in electronic markets or online stores like Amazon or eBay. Check the specifications and buy a genuine TLP 32C transistor to ensure the device’s proper functioning. - Arrange Resistor of 1k ohm
A resistor is an electronic component that restricts the flow of electric current through a circuit. In this step, you need to arrange a resistor of 1k ohm, which is commonly used in electronics projects.
If you don’t have a 1k ohm resistor, you can use a 1.5k ohm resistor instead. However, please do not use a resistor with a lower value than 1k ohm, as it can cause damage to the circuit. If you only have a 500-ohm resistor, you can connect two in series to get an equivalent resistance of 1k ohm. This will work fine for the project - Arrange the wires
In this step, you must arrange some suitable wires for the device. These wires will be used to connect all the components of the device.
You can easily find these wires in any electronics store, and they are not expensive, costing no more than 0.3$ for a bunch of cables. You must choose the appropriate length and color of the wires according to your convenience. It’s crucial to ensure the cables are correctly connected and secured to avoid loose connections or short circuits. - Arrange a data cable
For this step, you must arrange a data cable you no longer use or don’t mind cutting. Cut one end of the data cable and strip the wires, which will be used to connect the components of the sanitizer device.
It’s important to note that you can also use a battery to power the device, but it will be more expensive than a data cable. Using a data cable is more cost-effective and convenient as it can be easily plugged into a power source. - Select Container
You can use a small plastic bottle or any disposable container that can hold the sanitizer for the container. The container size depends on your preference and the amount of sanitizer you want to dispense at a time. Make sure to clean and dry the container before use to prevent any contamination. - Inserting pipe in the water pump
To proceed with step 9, take the pipe you acquired in step 2 and insert one end into the inlet of the DC water pump. Make sure to push the tube in so that it fits snugly. The other end of the pipe will dispense the sanitizer, so wait to cut it.
The DC water pump will ensure that the sanitizer is dispensed in the right amount and at the right time. Using the same pump mentioned in the previous steps or buying it from the given link is essential to ensure compatibility and better functioning. - Tighten the tube
After inserting the tube into the DC water pump, tighten it securely so it won’t come off. You can use any adhesive, like glue or tape, to hold it tightly. This will prevent leakage and ensure the sanitizer flows smoothly through the tube.
- Create a hole in the bottle cap
In this step, you must create a hole in the bottle cap for the water pipe to pass through. Use a drill machine or any sharp tool to make a small hole. Be careful while drilling; you don’t want to break the cap or hurt yourself.
- Drilling for the wires
To proceed with this step, you need to drill another hole in the bottle cap. This time, the hole is for the wires of the water pump.
The position of hole should be at a suitable place, which can easily connect the wires to the proximity sensor and transistor. Ensure the hole is manageable; otherwise, the cables will not fit correctly. - Drilled Two Holes
In this step, you need to ensure that the diameter of both holes is the same. This will ensure the pipe and wires fit tightly and do not come loose. You can use a drill or any other suitable tool to ensure the holes are the same size.
- drilling completed
In this step, you need to insert the pipe into the hole drilled in the previous step. It would be best if you made sure that the pipe fits perfectly into the hole and is tightly bound. Once the pipe is inserted, it should look like the image below. This will ensure that the sanitizer solution can flow through the pipe smoothly.
- Pipe
You need to take the pipe and push it through the hole drilled in Step 11. Make sure that the pipe is pulled through so that it comes out on the other side of the bottle. This will ensure the pipe is securely fixed in the bottle and won’t come out.
- drill a hole for wires
In this step Pull the wires of the water pump through the hole you drilled earlier in Step 12. Ensure the wires are correctly passed through the hole without any damage or cuts.
- After drilling and wiring
After pulling the wires of the water pump through the hole drilled in Step 12, the setup should look like the image below. The water pipe should go into the bottle, and the wires should come out of the other hole. Make sure that both the pipe and wires are securely attached and not loose.
- Glue it here
It’s time to assemble the components, so apply some glue to stick the parts together, as shown in the image below.
- Placing the proximity sensor
Now, place the Proximity sensor and attach it firmly to the bottle with the help of glue or any other adhesive. Ensure that it is not loosely attached and that you don’t face any difficulties while using it.
