Description

The Thermistor Temperature Sensor Module uses and NTC thermistor to measure temperature and provides an analog output.

Key Features of The Thermistor Temperature Sensor Module:
  • Uses NTC thermistor
  • Measurement range of -55 to +125°C
  • Provides analog output of the reading
  • 3.3 and 5V operation

This module utilizes an NTC thermistor for measuring temperature.  The output is normally input into an analog port on a uC where it can be read and the temperature calculated.

Thermistors are essentially resistors whose resistance value changes with temperature changes.  NTC stands for ‘Negative Temperature Coefficient which means that the sensor resistance will decrease as temperature increases.

The thermistor is in series with a 10K resistor which creates a voltage divider.  As the thermistor warms up, the resistance lowers and the analog output increases towards Vcc.

The sensor is capable of reading temperatures in the range of -55 to +125°C with an accuracy of +/- 0.5°C.

Module Connections

The module has a 3-pin header on the assembly for connections.  The ‘-‘ pin is connected to GND, the center pin is connected to Vcc and the ‘S’ pin is connected to an analog input pin on the uC.  If the output goes in the wrong direction i.e. resistance goes up as the temperature goes up, reverse the power and ground pins.
