Hello, I have found one OP-AMP based design of the texas instrument can i use it using some modifications to measure temp using PT100 with ESP32? There is one exl sheet (Attached here also) in which we can add parameters like desired temp measurement range , Desired output voltage range of Op-AMP an...

Hello,

Can you please reply me for my previous post queries?

Thanks,

1) OK but I have connected all pins to GND in Schematic like as attached. Will it work? 2) I need one more help from you please. I am planning to use PT100 sensor in my design and i do not know how to connect PT100 with ESP32 Mini ADC Pins because I think PT100's output voltage may be very less (mV)...

OK thank you so much for quick reply. Will take in design.

appreciate your prompt reply.

I do have tow more queries 1) if i do not use integrated RTC of ESP32-MINI-1-N4 then can i use both the pins Pin11 & pin12 as normal GPIOs? I will not connect 32.768KHz crystal in this case. 2) I have seen that in GPIO0 & EN pins play role to enter module in download mode so suppose if i have to use...

OK. THEN ALL OF THEM WILL CONNECT WITH GND.

THANKS,

Hello, I need one help please. In ESP32-MINI-1-N4 I see that there are additional 8 pins which are mentioned as GND but in schematic given in module datasheet they have connected pin55 only GND and not others so please suggest what to do of those all additional pins should connect all of them to GND...

OK thank you so much for quick reply and confirmation.
