Youtube Video | mLink | NTC Temperature Sensor

Our latest video covers the mLink NTC temperature sensor. This is a serial I2C module that interfaces to a wired remote NTC sensor probe. The module continuously takes measurements and provides the results in centigrade via the I2C interface. The probe itself is on a 2 metre wire, so it’s quite a long one, making it extremely useful. It’s also waterproof.

This post explains how to install the library.

This sketch uses the mLink library to read the temperature (in oC) 
from the mLink NTC Temperature sensor module (SKU: HCMODU0186).

Please see Licence.txt in the library folder for terms of use.

#include "mLink.h"                          // Include the library

mLink mLink;                                // Create an instance of the library

#define I2C_ADD 0x54                        // Default I2C address

void setup() 
  mLink.init();                             // Initialise the library

void loop() 
  float temp = mLink.NTC_Temp(I2C_ADD);     // Get the temperature in oC
  Serial.print("Temperature: "); Serial.println(temp);
  delay(1000);                              // Wait a second before reading again
