B3950 10K Copper Head NTC Thermistor Temperature Sensor 5*25mm with XH2.54 Connector with 0.5 Meter Cable
The B3950 10K Copper Head NTC Waterproof High Precision Thermistor Temperature Sensor, measuring 5 x 25mm, is versatile and suitable for various temperature measurement applications.
Featuring a copper tip of 5 x 25mm size and an XH2.54 connector with a 0.5-meter cable, this sensor offers convenience and ease of use. Its Negative Thermal Coefficient (NTC) means that its resistance decreases as temperature rises. However, in practical applications, the relationship between resistance and temperature may not be linear. Therefore, relying on an accurate table of measurements from the accompanying datasheet often proves more reliable than using a linear formula.

Frequently Asked Questions
What is the accuracy of this thermistor?
The B3950 sensor offers a resistance tolerance of ±1% at 25 °C, yielding high accuracy when used with the manufacturer’s resistance-to-temperature lookup table.
Is the copper head fully waterproof?
Yes, the copper probe and sealed junction provide water resistance suitable for immersion in non-aggressive liquids. Avoid prolonged high-pressure water exposure.
Can I use this with an Arduino?
Absolutely. Wire the XH2.54 connector to an analog input via a pull-up resistor (e.g., 10 KΩ), then calculate temperature using the B3950 characteristic curve in your Arduino sketch.
