Need Help for an electronics project!

[BB12]

Hi,

I'm working on a project based on the black-pill(STM32f411ceu) board,similar to this(SunLeaf | Hackaday.io) .

I will be only interfacing 2 sensors(3 max) with the board using SPI,UART connections.

Its data will be uploaded to a thingspeak page via esp8266.

Can anyone please help me in this project? Or guide me to some helpful resources?
I dont know anything as to how to do it....
TIA

A Raspberry Pi would be easier as there will be a lot more documentation. What sensors are you using?

It is supposed to be a compact module...that's why I'm using the stm board...

Just a pH and temp & humidity sensor

What is the purpose of measuring this? Hydroponics?

Why can’t you just use an ESP directly then? Why do you need the STM ?
Just search for ESPHOME or any custom esp firmwares

Yes hydroponics

Do you mean the esp32?

Doesn’t really matter. You can use 32 or 8266.

check out the below guide. Hardware wise this is what you will need. To integrate with thingspeak you’ll have to do some protocol conversion -

Yes hydroponics

OK. Please let me know when you have successfully implemented.

Esp32 is cheaper at at around 350 /board...
I will chech the article out

Yes Done!

ESP32 consumes more power than 8266, for just data collection 8266 should be sufficient.
