Temperature Sensor NTC 10K B3435 Waterproof Probe Thermistor Accuracy Cold Storage Temp Control Sensor Probe 1M Cable

The NTC 10K Temperature Sensor is a negative temperature coefficient (NTC) thermistor, a passive electronic component whose resistance decreases exponentially as temperature rises. The “10K” denotes its nominal resistance of 10,000 Ω (10 kΩ) at 25°C, the industry-standard reference point. It converts temperature changes into measurable resistance variations, enabling precise temperature sensing, monitoring, and control across consumer, industrial, and automotive applications.
