ESP Home & NTC 8x


I would like to implement a project with ESPhome and thereby measure temperatures with NTCs 10KOhm

How can I implement this,

would it only be possible with the ESP or in conjunction with an MCP3008


Use the NTC component:

You may have to use a calibration filter as the ESP ADC inputs are non-linear at the extreme ends of their measurement range. See: Analog to Digital Converter (ADC) - ESP32 - — ESP-IDF Programming Guide v4.4.3 documentation

However if you are only using the middle of the ADC range this will be unnecessary.

hello tom_l

thank you for your answer, but what does that have to do with my question?

I would like to have multiple (8x) NTC queries

The ESP32 has 18 ADC input channels.

Ok, I’ve read that too, but how do I configure it?

By following the examples in the documentation that I linked to.
