This video really helps, thanks! I made this but whenever I try to put the battery, it automatically starts pumping; however after that it functions normally. Can you tell me what the problem is?
You made a mistake in connecting the pump to relay, you connected it to NC then pump stops only when we show our hands to ir sensor. I know you realized it and changed it to NO but why don't you mention it in the video?
Hi, Thank you for bringing this to our notice. There is a minor connection correction performed in the video. However the lable on screen at 6:05 indicates the correct connnections to be made which should be followed.
Hello, There might be some issue with the connection. The positive pin of motor or pump is connected with the NO pin of the Relay and the negative pin of the motor or pump is connected with the negative pin of the DC jack.
It depends on the solenoid pinout. If the solenoid can be triggered using a 5V signal, then the same circuit can be used and the relay can be replaced with solenoid
I am 3rd year b.tech student I selected this project as mini project But for me the relay is not triggering when hand is placed in front of ir sensor. Please tell me what will be the issue.
Hi, If you wish to use a switch as a master override to turn the dispenser off, you can add it between the VCC (red wire) from the adapter and the VCC junction that goes to the motor and sensor.
Sir Mera ir sensor ki red light glow ho rahi hai par jab me hat aage le ke ja raha hu tho work nahi ho raha hai red light hi hai. Mene ir sensor ke blue part ke up me gumaya plz hel
Friend my project is going just opposite, when objects comes in contact with sensor then motor stopes and when the object removed the motor start working
Hi Nitin, Please check the second last paragraoh in the video description. If the system is behaving differently, the steps given in the description may help you.
Hi, have you tuned the IR sensor, it has a small potentiometer on top that can be used for tuning , ensure that it turn on only when you get your hand close to it
Hi Prabhat, The adapter and relay used are 5 volts, hence a 9v battery cannot be used. You may howver use a voltage regulator to step down the 9v to 5v. A circuit built using the 7805 voltage regulator may help you.
Yes! As long as all your parts work with 9V safely (the motor, relay, IR module). You should be good to go. Otherwise you will need a way to step down 9V to 5V using buck modules
How do u get active high output on IR module? All Chinese modules have active low o/p. They give high when no obstacle and low when detected obstacle. Something is wrong or missing!
Hi, The sensor that ships with the kit is active high, hence it can be used in the configuration as shown. If you happen to have an active low sensor, you could work around this issue by connecting your pump to the NC pin of the relay.
To clarify the circuit once, this setup requires 4 sets of connections. These are as follow: 1. VCC from adapter -> VCC of relay module, VCC of proximity sensor and NO (normally open) pin of relay 2. GND from adapter -> GND of relay module, GND of proximity sensor and GND of pump motor 3. Output of proximity sensor -> input of relay module 4. Positive terminal of pump motor -> COM pin of relay module For more information refer our blog: www.robocraze.com/blog/post/automatic-sanitiser-dispenser
Hi, You can find the kit for this project here: www.robocraze.com/diy-automatic-sanitizer-dispenser-kit Using Arduino depends on your requirement and budget. This dispenser can be made without using Arduino as demonstrated in this video. However, if you wish to modify the system to include more sensors, LED's or any other peripheral which requires a microcontroller, then you could use an Arduino since its a low-cost microcontroller.
@@helalali6555 Since there is the addition of Arduino to the existing components in the kit, it will not be cheaper to use Arduino, however, if your application has additional requirements such as use of more sensors, LEDs, actuators etc. then it would be advisable to use an Arduino since it is easier to control those using a microcontroller
You can use ultrasonic sensor if you have a controller such as the Arduino. Without controller, it is not really possible as the a microcontroller is required to calculate the distance between pulses emitted by the sensor itself
If the sensor have a diode(LED) on the module then you can directly check its working just by giving power supply and checking if the LED status changes according to your requirements.
Sir you are going great but you must create a circuit diagram so that if someone didn't understand your language or connections in the video so he/she can refer the circuit diagram for their project Thank you ❤️

Yes, a phone charger can be used as a power supply if it meets the required rating of 5V 1A. However, exercise extreme caution while making connections so as to not cause any damage to the phone charger.
But.... Sir in last u cut the video....? .... Bcaz there is fault in your connection.... Thus why....The relay Start in low signal.... Pls sir make a full live video without any editing.... Otherwise... Ur video explanation is very... Gud... But my Project is not working with this circuit....
Hi, The relay is to control the power to the pump. We need the pump to turn on and off based on the output of the proximity sensor. The output of the proximity sensor is connected to the input of the relay. The output of the proximity sensor in itself is insufficient to drive the pump.
Hi, Please try powering your pump motor directly to see if it is faulty or not. If the motor powers on when conected to supply directly, there may be a problem with your connections.
Hi, Please check the steps given in the description of this video to ensure your potentiometer settings and connections are correct. We have discussed these issues in the description.
Hi, To clarify the circuit once, this setup requires 4 sets of connections. These are as follow: 1. VCC from adapter -> VCC of relay module, VCC of proximity sensor and NO (normally open) pin of relay 2. GND from adapter -> GND of relay module, GND of proximity sensor and GND of pump motor 3.

How many volt is the adapter
Is it work with phone charger
Regualr 5V 1A adaptor will work. Yes, most phone chargers will work, but do note that you will need to cut the wires
@@Robocraze thank you ok
I tried using a 9v battery, why doesn't it work? do you really have to use 3.7v?
Sir please explain how the adaptor is connected in the end...my project is incomplete...help me out please
The adapter is connected to the jack splitter. GND is taken as common and the VCC is passed through the relay to control on/off.
Is it okay to use 6v adapter but the single jumper delay module is 5v?
It is not recommended to use a source voltage higher than the component's voltage rating as it might end up damaging the device
I'm getting a problem pls help mine relaymodules both light glows but light on ir sensor doesn't glows pls help
Hello,
You can try adjusting the potentiometer and then check it out.
Thank you
This video really helps, thanks! I made this but whenever I try to put the battery, it automatically starts pumping; however after that it functions normally. Can you tell me what the problem is?
Same problem
Hello, It could be happening because any obstacle is getting detected while you put the battery.

With out motor relay is working on and off but if connet motor close the sensor not off if remove hand why bro
Hello,
There might be some issue with the connection. The positive pin of motor or pump is connected with the NO pin of the Relay and the negative pin of the motor or pump is connected with the negative pin of the DC jack.
Can the IR sensor handel 12v 500ma voltage constant from an adaptor? I wonder because the load is low.
Hi,
The adapter being used in the video is a 5v 1A adapter. A 12v adapter will not work since the IR module requires 5v VCC.
Sir, how long will it take for the product to be delivered if we order the kit which is mentioned in the video description???
We ship all orders within 1 Working Day.
Sir mera ak project hai lakin humse ir sensor or realy se motar nahi chal raha hai please help me
Hello, please raise a ticket on support.robocraze.com with your detailed query and images, and our team will get back to you at the soonest!
How did u open up the middle of the wire?
You can use a wire stripper or wire cutter to strip out the insulation
Can I do this with a 12v relay ??
You can, but ensure all your other components are also rated for 12V
Sir mainay battery use kari iski light nay battery khatum kerdi led light was continuously on.
Hi,
The LEDs can be desoldered to reduce power consumption or can be supplied with power from an adapter.
When connect the motor always on..
If not connect motor relay working good why

What's the input power supply
Hi,
In the video, we have used a 5v 1A DC adapter.
Hi there, if I was to add a switch to the circuit to turn it on and off. Where would I add the cables?
Hi,
If you wish to use a switch as a master override to turn the dispenser off, you can add it between the VCC (red wire) from the adapter and the VCC junction that goes to the motor and sensor.
