NTC Thermistor Temperature Sensor Probe 10K Waterproof 1M 3950 18650 Li-ion Battery 3.7v A mercury switch is anIntroduction : NTC stands for Negative Temperature Coefficient. NTC thermistors are resistors with a negative temperature coefficient, which means that the resistance decreases with increasing temperature. They are primarily used as resistive temperature sensors and current limiting devices. Need to measure something damp? This metal head precision 1% 10K thermistor is an inexpensive way to measure temperature in weather or liquids. The resistance in
