NTC Digital Temperature Sensor 100°C

The precision of NTC thermistors can be up to 0.1℃ and the time constant can be less than 10s. They are applied to thermal detectors in stables, as well as temperature measurement in food storage, medicine and health, ocean, etc. The thermistor sensor module sensitively measures temperature, although it can only output analog signals.

This module uses an NTC thermistor to measure temperature. The output is normally input to an analog port on a uC where the temperature can be read and calculated. Thermistors are essentially resistors whose resistance value changes with changes in temperature. NTC stands for "negative temperature coefficient", which means that the resistance of the sensor will decrease as the temperature increases. The thermistor is in series with a 10K resistor creating a voltage divider. As the thermistor heats up, the resistance decreases and the analog output increases towards Vcc. The sensor is capable of reading temperature in the range of -55 to +125°C with an accuracy of +/- 0.5°C.
