Hi.
I don’t have a tutorial exactly like this, but I have tutorials for each of those modules that can help you build your project:
– RPi Pico and DS3231: https://randomnerdtutorials.com/raspberry-pi-pico-ds3231-rtc-micropython/
– RPi Pico and microSD Card: https://randomnerdtutorials.com/raspberry-pi-pico-microsd-card-micropython/
– RPi Pico and DHT sensor: https://randomnerdtutorials.com/raspberry-pi-pico-dht11-dht22-micropython/

I hope this helps.

Regards,
Sara

This tutorial is written in Arduino.
Do you plan to make this also available with Micropython for a Pi Pico (W),
DS3231 and SD card reader?

Can this be done without the RTC. By just taking out all the RTC code and setting the temp reading for every 500ms?

I have a question. How many bytes are needed to store each data series? (Date, Time, Temperature ºC, and humidity).

Yes. It should be possible.
Unfortunately, we don’t have any tutorials for deep sleep or sleep/powerdown mode with the Arduino.
Regards,
Sara

I am working on this sample project, thank you. I want to powered my arduino promini 5v with external 18650 battery so I need to build battery saver code.
Is it possible to use deep sleep mode? For example
1. Arduino wakes up.
2. Collecting data from DHT 11 and RTC Modüle.
3. Writes up the data on sd card.
4. Arduino goes to deep sleep for 2 hours.

What do you think?

Thank you for this tutorial. good job.

I put the code posted above, but the serial monitor continues to show only the temperature!

How do I code for the sensor to read and record temperature and humidity together? thank you
