ntcRead()

ntcRead() returns the temperature of an NTC 3950 10kΩ sensor as an integer in 0.1℃ units.

int ntcRead(uint8_t ch)

Commands

Command	Arguments	Return Value	Operation
`ntcRead(ch)`	`uint8_t ch` — MPINO: analog pin number; MPAINO: overall analog input channel number	`int`	Returns the temperature of an NTC 3950 10kΩ sensor as an integer in 0.1℃ units.

Example

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);
}

Precautions

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.
