Adopt the NTC thermistor sensor, sensitivity is good The comparator output, signal clean, good waveform, driving ability is strong, for more than 15 ma. With potentiometer to adjust the temperature detection threshold Working voltage: 3.3 V to 5 V Output form: digital switch output (0 and 1) It has a fixed bolt hole, convenient installation
NTC Thermistor temperature sensor module is low cost, small size module. It is very sensitive to ambient temperature. It is generally used to detect the temperature of the surrounding environment.
Detecting range: >120 degree Analog and digital outputs On-board potentiometer and indicators 1% resistors to make this module more reliable and precise Operating Voltage: 3.3V ?? 9V Board Diameter: 40 mm.
