Product Description
This sensor is a B3950 10K NTC waterproof high-precision thermistor that can measure temperature in various applications. It has a stainless-steel tip of 5 x 25mm with an XH2.54 connector and a 2-meter cable. Its negative thermal coefficient (NTC) means that its resistance decreases as the temperature increases. However, the relationship between resistance and temperature is not linear, so it is better to use a table of measurements than a linear formula. The table of measurements can be found in the datasheet that comes with the thermistor.

Frequently Asked Questions
Is this sensor fully waterproof for submerged use?
Yes, the stainless-steel sheath and sealed cable entry provide a waterproof rating suitable for immersion in liquids, making it ideal for aquarium and industrial tank applications.
What interface does the B3950 10K thermistor require?
It connects via an XH2.54 connector to any analog input. Use a standard 10 KΩ pull-up resistor to create a voltage divider, then read the voltage drop to calculate temperature.
Do I need to calibrate the sensor before use?
The thermistor is factory calibrated to ±1% tolerance. For maximum accuracy, you can perform a two-point calibration against a reference thermometer and adjust your software lookup table accordingly.
