Liquid Level Indicator Using ULN2003
PCBway: only $5 for 10 pcbs from www.pcbway.com/?from=CZcouple
A water level indicator detects and indicates the level of water in an overhead tank and relays the information back to a control panel to indicate whether the tank has a high or low water level.
In this tutorial, I am going to use the ULN2003 IC to create a simple, inexpensive water level indicator.
Using this circuit you can easily control the wastage of water and electricity.
Watch this video, for detailed step by step instructions on how to build this circuit and to know how this circuit works. Towards the end of the video I will also discuss whether its really worth building this circuit.
Thanks

Best ever tutorial seen recently.... no one can explain more clearer
This setup works very well. I'm using arduino pro micro and NRF24L01 power adapter and everything works as expected. Thank you very much! 😃
Good job can i use 10 meter wire for the sensors ?
Thanks
You are welcome
thank you!
Welcome!
instant follow. Great video
Cheers mate 👍
i need same kind of circuit but for 120V and 3A. Any suggestions on how to achieve it?
Excellent video packed with tons of good information!
Thanks 👍
I got lost a bit. What is the transistor for? If I understood correctly the transistor was only used to make the light blink on its own? I understand the importance of the diode. For my project I was thinking of connecting one side of the coil to 5vGND the other side the coil to a 3.3v pin (esp8266) with the diode in between. That way when pin goes high, it would power up the coil, when pin goes low it powers off the coil. What would my way of doing it not work, or be wrong? Edit: So I did see video again, and noticed relay goes on and off because of the code you put in. I've seen a couple of short videos, like this one czcams.com/video/19UNeUmvOW4/video.html that connect power straight to the coil pins.
So I think I figured it out, but would like someone to confirm. For the coil to work it needs 5v, the adruino and esp8266 (which I am using) only have 3.3v as output. That is why we use the transistor which acts like a relay. With 3.3v the transistor "connects", providing 5v to the relay coils when then power on the NO side of the relay. Do I understand it correctly now?
Yes, that is correct If you connect the relay directly to the arduino, you can end up damaging the pin. The transistor works at low voltage and allows 5v device to work seamlessly
For 5:34 what does "SS" refere to?
Pin D10 of arduino nano is SS or Slave Select Pin

Cheers thanks
How much m and km range this project have and we use ardiuno nano to make
I will not recommend making this Its complete waste of time
Salute for this video... I have one doubt If my transmitter is in 3rd floor and my received in ground floor in between some wall 🧱 then it will work? If not then what will be the solution for this...please tell me
You can create a mesh and use few as repeaters
This is an interesting application of electrical engineering. +1
Thanks 👍
@@CrazyCoupleDIY You are welcome sir. Do work!
Woow this is great
thanks
Nice and thanks for the suggestion
Thanks. Which Lib you are using for DHT11 / 22 ?
Just the standard one mate
DHT sensor library by Adafruit Arduino library for DHT11, DHT22, etc Temp & Humidity Sensors use this one its handy
Thanks.. which lib you are using for DHT11 / 22 ?
Just the generic one
DHT sensor library by Adafruit Arduino library for DHT11, DHT22, etc Temp & Humidity Sensors use this one.
Nice and helpful video, many thanks...keep doing for Pi Pico also.
I already have one on pico czcams.com/video/vO_2XWJDF70/video.html
I think the ULN is a good choice due to it being a darlington array since a darlington has a very high gain and thus requires a small amount of current to turn on. I wonder if it would work with distilled water.
I have never tested it, but it's a good point
Cute🎉🎉🎉🎉
Thanks 👍

i need something like this for my fuel cell in my drift car. got any ideas for gas/ethanol safe version of this type of sensor?
this guy only copy and paste from the PCF 8574 Library. nothing original. Do some thing from yourself
Thanks Your word means a lot to me
Yes but where is feeler/antenna (I don't know de name of this object in english) ?
Thanks bro Your works is amazing
It's my pleasure
Hello, I appreciate your video; it was very useful. I also have a question about the sensor's sensing angle. I read that this sensor doesn't have a blind spot, but I want to reduce the sensing angle. I don't need it to sense 360 degrees, just between 100 to 180 degrees. Is it possible to reduce the sensing angle of the RCWL-0516 sensor? Alternatively, can you suggest some common materials that absorb microwaves and don't affect the waves? thank you
I created a toy gun using the sensor (something similar to laser tagging) To limit its area I used few layers of aluminium foil
Good baby looking
is this project can power a 12v dc motor?
You better of using this just to change a battery with in turn can drive the motor
Absolute genius
Cheers thanks 😊
Excellent work
Many thanks
In my rcwl 0516 detect range only 3 centimeter, can you help
Please check the input voltage.
@@CrazyCoupleDIY input battery Voltage is 13V
ULN 2000 series was standard fayre in the early '80's , driving anything from displays to servo motors. generally simple to implement and reliable 👍
😊
hi, friend. I was experimenting with this sensor and came to the conclusion that it is not useful for alarms. It is very sensitive and is triggered by the slightest movement of a branch. Furthermore, it is impossible to direct the detection beam. Lightning cannot be channeled with either aluminum foil or 2 cm thick iron. Any comment from you would be very helpful. greetings.
I agree to your point The way I limit its area of detection is by putting aluminium foil
Very nice explained sir keep it up 👍
Thanks 👍
Its been a while I havent used this IC. Are you going to create some projects using these ICs
Can you make a PCB for the water level indicator?
Great interface devices. But beware, don't go overboard...the total emitter current for the entire package is 2.5 amps...(according to the spec sheet) or .35 A/driver; and the total package is thermal limited with a maximum Tj of 125C and 67 degC per watt Tja. So, the maximum package power dissipation is 1.5 watts, meaning each output can be loaded with a 175 ma continuous load. (Pdip in free air)
Creative video, thanks :)
Thank you too!
The world's best teacher thanks sir
Pleasure 🙏
Perfect for large 7 segment displays. I used a lot of them in my projects
This chip is easily the most underrated chip around people always bang on about the 555 but it is rubbish. As engineer I never ever used 555 for anything as there are so many other ways to do what a 555 does with less parts, however the uln2003 is just excellent drive straight out from a micro no need for anything extra, drive relay coils or higher voltages ...it is just a brilliant chip.
Nice
I see this IC on computer SMPS,
I am not sure about that mate But we can definitely use it to operate the 12 volt fans
These are great in my VFD tube displays. I laugh at the fact that 24 volts on the anode is considered "high voltage"! Thanks for the video.
Great mate mate
Great video information about display tm1637, with examples and Codes included. Thank you.
Thanks mate
Very well explained! Awesome video!

This was a common stepper motor drive chip used in small school cnc lathes and milling machines in the early 90's. Stepper motor drives have come a long way since then.
So true 👍
correct me if I'm wrong, but in your diagrams you don't show the GROUND connection (8), or am I missing something?
That is correct The simulator did not allow me to add pin 8 (GND) pin
