Thermistor

maker

A thermistor is a type of resistor whose resistance varies significantly with temperature.

expanded

A thermistor is a temperature-dependent resistor, widely used for temperature sensing and control applications. It is characterized by a high sensitivity to temperature changes, which makes it suitable for precise temperature measurement in devices and systems requiring thermal management, such as HVAC systems and consumer electronics.

examples

In a 3D printer, a thermistor measures the bed temperature to ensure accurate heating control.

Commonly used in FDM (Fused Deposition Modeling) 3D printers for maintaining bed and nozzle temperatures.

A thermistor-based probe is used in an HVAC system to control air conditioning efficiency.

Implemented in building HVAC systems to optimize cooling and heating cycles based on real-time temperature readings.
