What specific considerations should I take into account when selecting an STM32F4 variant?
Hey guys, I'm selecting hardware components for a project and have chosen an STM32F4 microcontroller based on the project requirements. I'm considering using an LM35 temperature sensor. What specific considerations should I take into account when selecting an STM32F4 variant, and are there alternative temperature sensors with similar characteristics that might be more suitable? Key factors include available ADC channels, processing power of the STM32F4 variant, and the voltage output ranges and operating temperatures of alternative sensors.

Hi,this doesn't really seem to be a good choice economically.The F4 has so many peripherals that you may not use and its also expensive.why do you need high processing power?
Okayy, @Dtynin Whenever you are choosing an STM32F4 variant for your project with the LM35 temperature sensor, ensure the microcontroller has sufficient ADC channels and at least 12-bit resolution for precise readings.
Also, You will need to consider digital temperature sensors like the DS18B20, which offer the same kind of accuracy and ease of integration without requiring an ADC. 🙂
@Edison_ngunjiri During my research it was recommended to use the STM32F4 to accommodate processing, but I'd like to know if you can suggest any cost effective variant that's also compatible.
This depends on the number of samples you want to read per sec,and when you say processing, what exactly do you mean?
Ooh okay, when I said processing I meant To operate/manage the lm35 temperature sensor
