I use the Seeeduino Lorawan board.
I want to use the NTC thermistor as a temperature sensor, for that I followed this guide:
the following problem occurs:
the NTC resistance value is displayed as temperature, the decimal point is not correct but it is the temperature. If I touch my NTC, the resistance value or the temperature changes primarily. The temperature value even goes down and becomes negative.
What am I doing wrong? Code was only copied.
I still add pictures of the measurement and construction;
