The temperature sensor module is based on the DS18B20 sensor IC. It requires a special software routine to download the measured temperature. If you want a simpler device for sensing temperature, you could use the thermistor module [23]. The advantage of the DS18B20 is that it is calibrated and supplies the temperature in degrees Celsius.  Whereas as the thermistor module only provides an uncalibrated analogue signal.
