I am testing to get data from 3 FSR sensors that are connected on ADC1 pins, 34 ~ 39. But I can get data from one sensor that is connected on No. 34 pin.
Two FSR sensor that are connected on the other pins(35,36,37,38,39) are not work.
So I want to know ESP32 can be used just one ADC pin at same time.
Please reply me sooner

Hi.
I think you can use multiple ADC pins at the same time.
Try using a pin from ADC2 for one of the other sensors and see if that works…
How are you reading the sensors in the code?

I use your code “ESP32 Data Logging to firebase realtime database” you made. Instead of BME280 sensor, I connected 3 FSR sensors on ADC1 pin(34, 35, 36). But only no. 34 pin works, the other does not work exactly even if same circuit.
Due to I use wifi, so I can not use ADC2.

Ok.
But how are you defining the sensors on your code?
Each sensor object needs to have a different name.
Can you show me the lines of code where you define the sensors?
