Can i use this sensor for dc?

I'm going to use this with ESP8266 so I can show RPM value in webpage. Can I use 3.3v to supply power to this module? what output voltage from this module?

Sir, I want control the voltage using a 10K potentiometer, Vin=12V DC, and Vout= (between 0v-5v) from the potentiometer. So, I need a resistance R1, that will drop the voltage from 12v to 5v, in order to produce Vout = 0v to 5v from the potentiometer. But I am unable to calculate the R1 resistance value. Please help me in this.

can this Water Flow Sensor be installed directly in the pipe where tap water passes?

Pak, ini kartunya pake kartu sim card biasa spt telkom apakah bisa?

Any way to read 1mA resolution ?

Very good work, sir ! Is it possible to change the lux value of BH1750 sensor in W/m2 ? Thank you

I want to use 4 pzem004t sensors plz help sir in knowing the pins of arduino on which it is to be connected

Please someone list the components used in this circuit

This video really helped me a lot.....my sensor wasn't showing any readings then I realized the problem was with the source and ground connections. Thankyou❣

Boss how to write the rain sensor for uno using computer. Tq

just what I was looking for

i need your help how to contact you sir

I'll try using your video, as I have an ESP32 S3 board and an INA219 current sensor and using PlatformIO in VSCode and I can't see the current values. It only says `Talk is running`, which means it is reading, executing but the current values do not appear on the terminal. If you can give me a tip I would appreciate it! Or if I had a video from someone even better?

Hi, is it must to add an voltage divider in between the Rx of module and Tx of Arduino Uno?

Please my current sensor is 30A and after doing everything, my sensor is reading zero current when no load is present but it’s reading 2.5 voltage when no load is present as well

I tried same but with esp32 board and the heading is being displayed very wrong. It is stuck at 237.61. no matter how much I rotate the magnetometer horizontally, it remains the same.. I tried removing power of magnetometer. Amazingly, the reading was being updated the same even when the magnetometer was removed. I am stuck here and it doesn't seem to work. What do I do?

Gracias.. Can You tell me where can I Buy the SENSOR ...? Gracias

😅 gracias

hi bro, how to this with 2 wires ptd100?

AT+CCID ERROR The led is blinking once every second . what may be the issue??

hello, why mine is error?

Great and simple video

Is there's someone who have the same problem with me because the led light of my sim800l gsm module is not blinking but it stay on.

AT+CREG? +CREG: 0,3 how do i fix this? please help me

This library only works with specific backpacks

what is the unit of the current output? is it amps or milli amps

thank you so much. you're a life saver. I didn't connect the gnd of my power source to the GND of arduino earlier.

Please show how to let the sim send each second a signal to my phone oder to a webside. Or how I set a time lile 1/minute 1/sec ...

Can you make a amplier for mr

Hi

Ji

yes

can you do this without arduino? with c++

Can I use 100ohm resistor to limit the current to the gsm?

Does it work with Sonoff?

great how many volts is the coin operated. With 12 volts?

Hello, I would like to measure the power of a solar panel, but I do not know how to connect it as on your circuit. I have an INA219 sensor. Should I plug it in instead of the diode? And is it a problem if my solar panel is 1Watt and delivers a voltage of 5.5V?

hi can i get a gcash payment for that method sir? thanks

I would have watched the video but the music is very annoying

the library "ACS712" for the AC current is not showing up on github

so this can be connected to arduino without external power supply?

5v..? Not 3.3v..?

hey there, sorry to bother you! If you're calibrating this sensor using a measuring tool, how much water do you use for calibration? Also, after a few tries, how do you end up with a value like 2.663? Do you take an average? If yes, how do you figure out the average?

I still get Nan message when running the code and the sensor. But, there is something different between my voltage source. I use dimmer instead of Main AC, like shown in the diagram to control a heater. Could that be the cause? Thanks in advance

hey brother, can i ask what is the command to register to a network?

Hi, great tutorial. where did you get the RH_RF95 lib for arduino? Thanks
