About this product
An MF52 negative temperature coefficient (NTC) thermistor with a nominal value of 20 kΩ. Its resistance decreases as temperature rises, which makes it a low-cost choice for temperature-sensing applications in student and hobby projects. It is typically read through a voltage divider connected to an analog input.

Frequently asked questions
How do I read temperature with this thermistor on an Arduino?
Build a voltage divider: connect the thermistor between 5 V and an analog pin, and a fixed resistor of similar value between the analog pin and GND. Convert the ADC reading to resistance, then to temperature using the thermistor's B-value or the Steinhart-Hart equation.
Which fixed resistor should I use with it?
Use a fixed resistor close to the thermistor's resistance at room temperature for the best sensitivity around that range. Confirm the B-value and exact characteristics in the datasheet for accurate conversion.
