ntcReadf() returns the temperature of an NTC 3950 10kΩ sensor as a floating-point value in ℃.

float ntcReadf(uint8_t ch)

void setup() {
  Serial.begin(115200);
}
 
void loop() {
  int temp10 = ntcRead(0);  // Return the NTC 3950 10kΩ sensor temperature as an integer in 0.1°C units.
  float tempC = ntcReadf(0);  // Return the NTC 3950 10kΩ sensor temperature as a floating-point value in °C.
 
  Serial.print("NTC = ");
  Serial.print(tempC, 1);
  Serial.println(" C");
  delay(500);
}

• ntcRead() is based on an NTC 3950, 10kΩ at 25 C sensor.
• ntcReadf() divides the ntcRead() result by 10.0F, so its resolution remains 0.1 C.
• Connecting a sensor with a different B value, reference resistance or wiring configuration causes temperature errors.
• On MPAINO, the temperature is incorrect unless the DIP switch is in NTC mode.
• On MPAINO, the first call internally initializes only the corresponding analog input module.
