Arduino - Connecting Multiple Sensors

[@djnarwhale1277]

I'm new to these kinds of things and I'm looking to connect multiple of the same sensor to one Arduino, how would I do that?

[@myinfo7114]

There is a new approach in science for reading an unlimited number of sensors in parallel. It is called "photon-pixel coupling". Maybe you can do it with an Arduino since it supports a cam.

[@186scott]

Can you run a water temp sensor, oil pressure and speed sensor and send it to a raspberry pi to display

[@BasementElectronics]

Certainly. Two important factors are making sure the ground is common for all your devices, and make sure your devices are powered directly from your power source (battery, power supply, etc.) and not from the 5v/3.3v lines of your Pi. The Pi tends to struggle providing enough amperage when you have more than two devices

[@186scott]

@@BasementElectronics thank you and I am sure I won't have a power supply issue as I'll be using power from the cars battery and stepping down from that to a stable 5v and making sure I do the same thing with the 12v sensors and I am aware it will be a headache doing the programming

[@BasementElectronics]

If you have your power sorted out, you should be alright. The rest is just keeping track of your data pins.

[@186scott]

@@BasementElectronics yh that will be easy and doesn't help it has been 15/16 years since I did coding but I am sure I will remember/relearn it all

[@BasementElectronics]

Arduino has a lot of good example code to guide you along. Don't be afraid of cut/paste 😉

sir how to connect pir motion sensor, pulse sensor, eye blink sensor and mems mpu -6050 sensor in one arduino uno board?? is this possible in one board?? can teach me how to connect it since some of the sensor share same port

[@parthajana3365]

Hallo sir , what will be the arduino code for connecting two ir sensor with a single arduino. Please help me with this

[@manojbaviskar9162]

How many sensor should we connect on ardiuno at a time?

[@BasementElectronics]

You can connect as many sensors as the Arduino pins will allow. This grows when you use I2C and SPI. What yo really have to watch is your power. I recommend powering your sensors separately from your Arduino (common ground wire, though). The power output from the voltage pins on an Arduino is very limited. Running too much will cause strange results because the sensors can't run (I speak from experience)

[@sushildamle3449]

To avoid erratic results, I have given external power supply to USS and Servo SG90 motors.

sir how to connect two different gas sensors(MQ2,MQ135) in single arduino with lcd sir

[@nurulsyahira2597]

hi sir.. i'm trying to connect retro-reflective photoelectric sensor, ultrasonic sensor and servo motor with arduino uno. is it possible?

[@angeldomantay]

Curtis Ireland hi sir i have the same problem. I wanted to connect retro reflective sensor with the stepper motor. Im having a hard time to combing both of them...

[@alexagordn]

hi, im trying to connect two gps modules NEO-7M to arduino uno r3. is it possible?

[@silvernemesis13]

Hello sir, i have a question. i have five different sensor modules and i will power each sensor 18650 3,7 v lipo (MT3608 3,7v up to 5v). I set MT3608 to 5v, then when the sensor module powers up, it drops from 5v to 4.40v. What is the wrong, i dont understand my mistake.

[@TJbuffs]

I have noticed my arduino will drop power sometimes. I have heard if it is a "knockoff" brand this happens more. I am no expert, just repeating what I have read and experienced. Capacitors may help, depending on the situation I guess. Again, no expert, just trying to help.

[@silvernemesis13]

@@TJbuffs Thank you, i will try to use capacitor :)

[@TJbuffs]

@@silvernemesis13 of course, you may look into that more though. Where to place it, what size of capacitor. etc. I think people use a 10, and place it from the 3.3v to GND. But research it, do not take my word for it. Hopefully that at least gets you started!

[@dominicgei8227]

not sure if you have put the project to work yet, but I'm very interested on a live update, and review of powering everything by solar and the working of the sensors (especially about the soil sensor). Thanks

[@abman1662]

Did you make the video on Raspberry pi ?

[@abman1662]

Yes i was talking about reading from Arduino via serial port. Understood. Thanks for the reply

[@DanielGarza0]

Why is the diagram small and your face full screen?

[@BasementElectronics]

I made this video over five years ago. I would hope my skills and techniques have improved since then. I do take comments like this seriously though so I can at least try to improve. Thank you for watching and commenting.

[@aquilinapaul9107]

can i have your email for some questions

[@muthuselvi8637]

i want coding for this project

[@parthajana3365]

Ir sensor for remote

[@tubeDude48]

Boring!
