I need to interface Lmt88dckt Temperature sensor with esp32- esp-idf. Is there any sample example on how should I interface it ? And what equation to be used to convert ADC readings to temperature?

Dear Sara -

the formula for converting the output voltage of the LMT88 to temperature (in C) , with a worked example first shows up on pages 7 and 8 of the LMT88 datasheet.

http://www.ti.com/lit/ds/symlink/lmt88.pdf

following that section is also a lookup table in case you want to implement that in your MCU code and use it and pages 10-12 cover even more on the same topic.

I would recommend you take a look here for ADC usage code examples for that MCU

https://docs.espressif.com/projects/esp-idf/en/latest/esp32/search.html?q=ADC&check_keywords=yes&area=default

if you want to move to TI based MCU which supports Wi-Fi, have a look at the CC3220S, CC3220SF and CC3235SF devices
