Hello , Nice explanation !!, A quick question . The 5V DC Relay is controlled by a ESP32 3.3 V Pin voltage. Is this oK . Thanks

Controlled by 3.3V but powered by 5V DC adaptor. Thanks

in this project what about data ...everytime we turn it ON or OFF ...is there any place the data save

[@acefuzzball7969]

Hi Sir i have question how can i control relay manualy and using automation? for example, control relay to turn on/off fan using webserver and using TTP223 touch sensor, i tried and it doesnt work together i can only use 1 of that for control relay

Hello great video! But I am wondering, if it is possible to make real time charts showing actual values and alao historical data, also presented by charts and available online anywhere. Example project: weather station, electricity metter.

[@joedgoh]

Yes, there is a widget for that. However, for the free account, only 1 day data retention. You need to upgrade for historical data.

Great video thank you. I can’t get the arduino connect to see my ESP32. Any idea?

If i use 12 volt battery supply how much value of resistor that i have to use and also i use 12 v dc motor and 0.3 A

[@IrfanShaikh-g4v]

@joedgoh Its amazing video brother.. I need to know that if we wanna add soil moisture sensor along with the same project and set the specific range so the motor should start automatically. Is it possible to do? and how can we achieve this. If you add it in the same project then it will be a great help and I will really appreciate. Thank you

[@iam_muni_baa]

Great work sir thanks

[@marygamal9095]

can i use Arduino UNO and ESP8266 instead of ESP32 ?

[@ajinkyaudamale5800]

Can you please make video on Arduino cloud iot and x9c104 digital potentiometer

[@neerajgupta1251]

Hi Very good video. I was not very clear why you connected the ESP32 ground to the external 5 V supply gound. Please explain the logic. can the motor work with this ground connection. Thanks

[@joedgoh]

It is just so happen that my motor and my relay are both 5VDC, so I used the same external 5V supply. For the relay module to work, it requires 5V, but it must be of common ground to the rest of the circuit. If in case you have a motor that operates on a much higher voltage (ex. 12v, 24v, etc), use a seprate supply to it and DO NOT connect its ground to your circuit. It should be separated and only connect it to the output side of your relay.

[@jaikrish50]

5 volt dc is safe for esp32?

can I use esp8266 instead esp32 cam?

It depends on what purpose. ESP2 cam has a specialized purpose highlighting the integrated camera while esp 8266 doesn't have.

Hello sir, beginner here. I did all your steps right before uploading sketch. ufortunately, it can find any device associated with it. so it fails to upload the code. My model of esp32 is wroom-32. I selected that but it still dont work. Please help

[@joedgoh]

Did you select the same board I am using in my video? esp32 dev module?

[@jhunardchristianasayas7134]

Yes I did sir. Thank you for replying. I already figured out why. Why computer doesn't recognize the esp32 so I have to install the drivers to it. I just love this work, troubleshooting problems until you make it work is the best feeling. Ive met many more issues but fortunately, I found way out. Like when I added an i2c lcd to it to show the values of temp and humid. I also configured few of the codeds that make it automatic to turn on the fan whenever a threshold of temp is reached. Again thank you, and hopefully, I can accomplish my project using esp32. Keep doing a great job sir!!!

[@joedgoh]

That's great. Good to know! 🙂

[@jhunardchristianasayas7134]

@@joedgoh Hello sir, Can you actually automatically turn on the motor and LED switch if the temperature and humidity level reaches a threshold? for ex. if temp >= 32, the fan turns on, and turns off when it gets lower than that? thank you!

[@joedgoh]

Of course, a simple if condition in your Arduino code can do that.
