ESP32 Internal RTC Timer control Relay without RTC module | Real-Time Clock with NTP Server
Вставка
- Опубліковано 4 жов 2024
- In this ESP32 project, I have shown how to make an ESP32 internal RTC timer control relay without any external RTC module. The ESP32 will get the time from NTP server initially, then it use the internal RTC to control the relay.

I have covered the following topics in this ESP32 RTC project tutorial:
02:38 Required components of ESP32 project.
03:16 Circuit of the ESP32 RTC control relay.
04:14 Source Code for the ESP32 internal Real Time Clock.
04:36 How to get the NTP server for your country.
07:28 Control the relay using ESP32 internal RTC Timer.
Required Components for the ESP32 internet of things project.
1. ESP32 Devkit V1.
2. 1-channel 5V SPDT Relay Module.
3. Switch

Important points:
1. You don't need any external RTC module like DS3231.
2. Initially ESP32 need WiFi, just to fetch the current time from NTP server.
3. You have to update the NTP server according to your country.
4. Mention the ON/OFF time in 24H format (as shown).
5. Please take proper safety precautions while working with high voltages.
During the ESP32 tutorial video, I explained all the steps to make this ESP32 home automation system, and how to fetch data from NTP server.
In this ESP32 project, you can control the relay using ESP32 internal RTC, so you don't need Wi-Fi connection all the time.
Here the switch is connected across the COM and NO terminals of the relay. In upcoming videos I will add more features to this ESP32 timer project.

Sukses selalu terimakasih videonya semoga ilmunya betkah Pa Guru. Salam dr Indonesia
awesome ideas and free projects that's great sir your projects help me very much thanks for uploading these type of projects.👍👍
This is really what I need... thanks Bro
That's exactly what I needed!!
Can i add multiple relay and if yes how?
You can change the on/off time with two buttons and save this in flash memory.
Many thanks! Helpful!!
Welcome
Why not giving eeprom update that's distarv the alarm time when tha light is gone
Why did you multiply 5.5 and not 5.30 ?
can you make a tutorial sir about fm transmitter monitoring can monitor wattage of output ang return power with relay
Timer multiple time use kar sakte hain
you have to create your own RTC and updated with NTP server incase you lost connection,
Sir Cadio Home automationwith fan dimer plz
Sir one home automation project with esp32 +ir remote+ alexa+manual with sinric plz plz
Can we do same with esp8266
круто, но в идеале должен быть веб интерфейс для перенастройки времени. спасибо.
Bro can k control 12 volts lights with it?
What does the daylightoffset_sec do?
set time through web base
can i use esp 8266???
What if there's power failure
Maybe the live n neutral cable is switched
can u work for me
How to donate ? you have paypal
Yes... link in description

Data stored in-side esp 32 rom .so it will remember relay State asper project he used preference library's or you can use eeprom.h library
