B3950 Sensor 20mm – 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 the B3950 thermistor waterproof?
The probe’s stainless-steel sheath provides water resistance suitable for splashes and immersion in liquids. For prolonged submersion or high-pressure applications, verify compatibility with your enclosure.
How do I interface this sensor with a microcontroller?
Connect the XH2.54 plug into your board’s two-pin socket, form a resistor divider using a known reference resistor, then measure the voltage drop with an ADC input. Convert voltage to resistance and use the B3950 lookup table to derive temperature.
Can this thermistor read temperatures below 0 °C?
Yes. The measurement range covers –20 °C to 105 °C, making it suitable for sub-zero environments such as refrigeration chambers and outdoor monitoring.
