Thermistor Module is a temperature sensor module which senses the temperature by the thermistor and converts it into a digital and analog output. The thermistor is the short form of thermal resistance and its resistance increases and decreases in the proportion of temperature. As this is an NTC, so its resistance decreases with increase in temperature. 

The module has on-board a variable resistor or potentiometer knob, that is used to change the sensitivity of thermistor by adjusting knob. This device has the precision up to 0.1 °C and time constant less than 10s.
